The best boat trailer jack is the one that holds your trailer tongue steady at the ramp, cranks smoothly with one hand, and survives salt water without seizing up a season later. Most factory jacks are the weakest link on a small trailer, and most replacement jacks on the shelf today are variations on the same four bolts and one square tube.
We went through twelve tongue jacks in this roundup, from a 1000 lb single-wheel swivel to a 2000 lb dual-wheel unit with an adjustable drop leg. Every one of them bolts or welds to the same kind of tongue, so the differences come down to capacity, drive type, wheel size and coating. If you want a broader look at trailer hardware, we also track the best trailer jacks overall and the best trailer tongue jacks separately.
Before you buy anything, you need one number: your tongue weight. A boat trailer jack carries roughly 10 to 15 percent of your fully loaded trailer weight. On a 4,000 lb trailer ready to launch, that is 400 to 600 lb sitting on the jack, which puts a 1000 lb rating close to its comfortable ceiling. Anything heavier and you want to jump to 2000 lb.
Here is what matters before you spend money, and it is the same short list the shopping engines rank by. Size the jack to your loaded tongue weight, not to the GVWR sticker. Decide whether you need wheels or a fixed foot and drop leg. Pick a coating that matches your water, meaning galvanized or stainless if you launch in salt or brackish water. And check that the bracket swivels or folds up so it does not drag in transit. We answer each of those in the buying guide further down.

1. Jeremywell 2000lb Dual Wheel Jack – Best Overall Boat Trailer Jack
- Galvanized alloy steel resists corrosion
- 2000 lb capacity handles heavy boat and RV tongues
- Dual 6 inch wheels roll and steer over varied terrain
- Bolt-on swivel bracket
- 12 inch of smooth side-wind travel
- No printed instructions included
- Mixed SAE and metric hardware
- Clamp-style mount can slip on the frame
This is the jack we would put on a mid-size boat without hesitating. It carries a 2,000 lb lift rating, which puts it comfortably above the tongue weight of most single-axle and tandem-axle boats under about 5,000 lb loaded. The galvanized alloy steel construction is the kind of finish that survives a wet winter on a boat lift.
The dual 6 inch wheels are the feature that changes daily life. A single caster digs into gravel and wet sand at the launch ramp, and you end up fighting the trailer. Two wheels spread the load, and owners consistently say the difference is obvious the first time you push the trailer down a ramp alone.
Travel is 12 inches, with a retracted length of 26 inches and an extended length of 38 inches. That range covers most standard tongues between 3 and 5 inches tall and gives you room to match a truck hitch without cramping the inner tube.
Installation is the one weak spot. There are no printed instructions in the box, so you are working from the bracket itself. The hardware kit is complete, but a few owners report mixing SAE and metric fasteners, with the handle grip needing a 16mm socket. Budget an extra 20 minutes and check the bracket orientation against the tongue height before you tighten anything.
How the Jeremywell performs on gravel and sand
Dual wheels are the whole reason this unit is our top pick. On a soft boat ramp, the extra contact area keeps the jack from sinking and keeps the trailer from tipping as you crank. Reviewers who replaced bent or stripped factory jacks report the same thing: the tongue stops wobbling as soon as the load transfers to two wheels.
Who should skip this jack
If your trailer is a small PWC or jet ski rig under 1,000 lb, you are carrying more steel and more capacity than you need. A 1000 lb unit will do the same job at a lighter weight and is easier to install one-handed. The clamp-style mount also deserves a second look on a trailer with a thin or unusual tongue, because owners report it can creep once the frame is flexing.
For a boat you actually load with people, fuel and gear, the headroom here is worth carrying.
2. VEVOR 1000lb Swivel Jack – Best Value Boat Trailer Jack
- Sturdy alloy steel for the money
- All mounting parts and instructions included
- Swivels out of the way for clearance
- Smooth crank with a comfortable handle
- PP wheel resists salt and wet conditions
- Mounting holes must be aligned vertically
- 1000 lb rating is light for larger pontoon boats
- Some buyers added extra bolts for non-standard brackets
This is the jack we recommend for a small boat, a jet ski trailer or a light utility rig. It holds 1,000 lb, adjusts across a 12.8 to 23 inch range, and the inner and outer tube design feels solid when you put the crank handle on it. Reviewers describe it as sturdy and easy to install, and the 4.7 average across more than 650 ratings backs that up.
Two details set it apart from the other budget options. The box includes every mounting part plus assembly instructions, which sounds minor until you are kneeling in a driveway with a jack and no idea which way the bracket goes. And the wheel is a 360 degree PP caster that rolls in any direction without marking the ramp surface.
The swivel bracket is the feature to pay attention to. It folds the jack up and out of the way when you are towing, so you do not have to crank the leg all the way in to gain ground clearance. On a shallow ramp approach that alone can be the difference between loading the boat and dragging the tongue.
The one setup mistake owners keep making is mounting hole orientation. If the three holes are not lined up vertically, the jack sits crooked and the inner tube binds. Check it twice before the final bolt.
Where the VEVOR fits in the boat trailer lineup
It is a strong match for anything under roughly 1,000 lb of tongue weight, which covers a large share of pontoon-lite boats, fishing boats on single-axle trailers, and personal watercraft rigs. Owners also use it on utility trailers and small mobile rigs, where the 1,000 lb rating is not close to being tested.
The alloy steel tube resists corrosion, and the PP wheel tolerates wet and salty ground better than a steel wheel that pits and sticks. Neither part is marine grade in the way a stainless or Dacromet-treated jack is, so rinse it after a saltwater launch.
When you need more than this jack
The ceiling here is real. Once you are pushing a pontoon, a cabin boat or anything with dual axles over about 3,000 lb loaded, tongue weight climbs fast and a 1,000 lb jack is working at or past its limit. Move up to a 2000 lb model rather than stretching this one. If your tongue is thicker than the supplied bolts reach, plan on longer fasteners.
3. YOMILINK 2000lb Dual Wheel Jack – Best for Heavy Tongues
YOMILINK 2000 lbs Trailer Jack with Dual Wheel, Heavy Duty Swivel Boat Jack
- Genuinely heavy duty construction
- Dual wheels roll noticeably better
- Bolt-on or weld-on mounting
- Powder coat over galvanized tubes
- One year manufacturer warranty
- Outer tube can bow under heavy load
- 20 lb of steel to lift into place
- Galvanized finish still shows surface rust in coastal use
This is the one to look at if you are replacing a factory jack on a trailer that has been outside for 20 or 30 years. The 2,000 lb rating and the heavy carbon steel body are what owners notice first, and the overwhelming theme in reviews is that the lifting power feels completely different from what came before it.
Height adjustment runs from 25.5 to 37.8 inches, which fits trailer tongues between 3 and 5 inches. That range is taller than most jacks in this group, and it matters if you need to match a tall hitch or lift the tongue clear of a high kerb.
Dual PP tires are specified to resist sinking into mud, gravel and sharp rocks, and that is not marketing filler. The expanded contact area is why owners report rolling noticeably better than a single-wheel jack. If your launch site is a shallow sand ramp, this is worth more to you than any coating choice.
The coating is galvanized inner and outer tubes with a powder finish on top. That is a solid marine-oriented stack, but coastal owners still report surface rust appearing over time. Rinse it with fresh water after every trip in salt water.
Why dual wheels matter more than capacity here
With a 2,000 lb rating and 20 lb of steel, the loaded tongue sits close to this jack’s working range. Two wheels distribute that load so the frame and the tube see less point force. Reviewers who upgraded from a single-wheel jack say dual-wheel stability is the single reason they would never go back.
There is one design tradeoff worth knowing. Some owners report the outer tube bowing outward slightly when supporting heavier trailers. It has not stopped anyone from using the jack, but it is the reason we rate this one as best for heavy tongues rather than best overall.
Who should consider the alternatives instead
If your tongue weight sits under 800 lb, this jack is more steel than you need and heavier to wrestle into place. A 1000 lb unit will lift the same tongue with less effort.
If you tow on rough ground every single trip and rust is your main worry, the Dacromet-treated hardware on the TOWKING jack later in this roundup resists corrosion far better than a powder coat over galvanized steel.
4. Torin 1000lb Swivel Jack – Best Budget Boat Trailer Jack
Torin Trailer Jack with Wheel, 1000 lbs Heavy Duty Swivel Boat Trailer Jack
- Low-cost bolt-on replacement for a failed factory jack
- Largest review base in the group at about 2200 ratings
- Bolts on quickly
- Side-wind crank raises smoothly
- Swings up for storage
- Swivel locking pin is short and moves loosely
- Thin alloy steel that feels cheap under load
- Handle can strike the ground
- Overloading destroys the wheel and gears
With more than 2,200 ratings, this is the most-reviewed trailer jack in the group, and that cuts both ways. The 4.2 average tells you the story: plenty of owners are happy, plenty are not. We include it because for a light trailer it is a functional, low-cost swap, not because it is flawless.
The design is simple. A zinc-painted alloy steel body, a 6 inch wheel, an adjustable range of 10.5 to 20.5 inches for tongues between 3 and 5 inches, and a side-wind handle. The swing-back bolt-on bracket lets the jack fold up for storage.
The defect that shows up most often is the swivel locking pin. It is short and moves loosely in the bracket, which makes it awkward to align and easy to dislodge. One detailed owner account describes the jack collapsing under a boat when the pin pulled out of the mounting frame. If you buy this one, check the pin with a flashlight and drive a retainer through it if the hole allows.
Overloading is the failure mode to respect. Reviewers repeatedly warn that exceeding the 1,000 lb rating snaps wheels and damages the internal gear assembly. Stay under it and it will do its job for a light boat trailer.
Where a budget jack makes sense
A small fishing boat on a single-axle trailer, a jet ski rig or a light utility trailer that lives on a flat driveway. In those conditions tongue weight is modest and the jack is lifting the trailer off its coupler a few times a week at most.
The zinc coating is the minimum acceptable finish for marine use. It will not last forever in salt water and it is not a substitute for annual maintenance, but on a freshwater lake trailer that gets rinsed down in the spring, it is fine.
When to spend more instead
If your trailer is heavy, if you launch in salt water, or if the jack is your only support while you work on a tire, the loose locking pin is not a small issue. It is the difference between an inconvenience and a trailer on its side.
The VEVOR in the same capacity class ships with a full hardware kit and instructions, and the CURT 28112 carries a limited lifetime warranty on the body. Both are stronger picks when the budget allows.
5. CURT 28112 Marine Jack – Best Premium Marine Boat Trailer Jack
CURT 28112 Marine Boat Trailer Jack with 6-Inch Wheel, 1,200 lbs., 11 Inches Vertical Travel
- Well-built zinc plating holds up in salt water
- Several owners report four years of seasonal service
- Heavy-duty pull pin locks the swivel securely
- Bolt holes align with many OEM mounts
- Limited lifetime warranty on the body
- No mounting instructions included
- Mounting rails bow if installed vertically
- Bracket groove misaligns on thick tongues
- Not made in the USA
This is the marine-grade jack we trust in coastal water. CURT rates it at 1,200 lb for both lift and support, which is unusually honest specification, and the zinc plating is specified to resist water, dirt and road salt. Owners running coastal and freshwater boats report it still working after four years of seasonal use.
It is also the easiest of the higher-capacity jacks to fit in place of an existing mount. The included 3/8-16 x 4 inch bolt-on hardware fits frames from 2×2 up to 3×5 inches, and several owners report the bolt holes line up with OEM mounts, which turns the swap into a ten-minute job.
Travel is 11 inches through the side-wind handle, from 12.5 inches retracted to 23.5 inches extended. The 6 inch wheel makes coupling and positioning easy, and the swivel bracket with a heavy-duty pull pin locks into place for towing clearance.
The mounting caveat is worth repeating because owners hit it repeatedly. On tongues thicker than about 2.5 inches, the bracket groove needs to run vertically or the long mounting rails bow under load. Get it wrong and the plate flexes every time you crank.
Why the warranty matters on a marine jack
CURT backs this one with a limited lifetime warranty on the jack body, plus one year on finish and parts. Forum owners repeatedly name that warranty as the reason they chose CURT over a budget replacement they would replace again in two seasons. When your jack lives in salt spray and gets hosed down once a year, a structural warranty is worth real money.
It is also worth pairing with the trailer stabilizer jacks we recommend if your boat sits on a sloped driveway, since the tongue jack handles height and the stabilizers handle side load.
When the 28112 is not enough
At 1,200 lb, this sits between the small-trailer class and the heavy class. A dual-axle boat over about 3,500 lb loaded will push tongue weight toward 500 lb, which still fits, but leaves little margin if you tow with a full fuel tank and several people aboard.
If your jack has to hold a tongue for a full day while you work, go up a size rather than up a brand. The 2000 lb dual-wheel units give you far more margin for the same money as a premium 1000 lb jack.
6. Ultimate Trailer Jack 2000lb Top Wind – Best for Ground Clearance
The Ultimate Trailer Jack – USA-Owned – Fastest Jack on The Market – 2000lb No-Crank Tongue Jack for Boat, RV & Utility Trailers
- Top-wind layout keeps the handle clear of the frame
- Drop leg plus fine crank gives a wide adjustment range
- Retracts flush with the frame
- Internal roller bearings reduce cranking effort
- Zinc-coated steel exterior
- Mounting hardware not included
- Top-wind handle is awkward to reach when fully lowered
- 12 lb of steel to lift onto a high tongue
The defining feature here is the top-wind drive. The crank handle turns over the top of the jack instead of sticking out sideways, so there is no handle swinging into the trailer frame and nothing hanging down to strike the ground. That is a real problem on side-crank jacks, and it is the reason this design exists.
The adjustment range is genuinely wide. You drop the outer tube for up to 12 inches, then use the 15.5 inches of fine top-wind travel to dial in the exact height. Rated at 2,000 lb lift and 3,000 lb support, it retracts flush with the trailer frame when you are done.
Internal roller bearings are the detail owners mention most. They cut cranking effort noticeably on a jack this size, which matters if you are raising and lowering a loaded tongue several times a day at a busy ramp.
Plan on buying mounting hardware separately. The jack installs bolt-on and the kit is not included, which is the single most common note in reviews. Check your tongue dimensions and pick the plate and bolt size before you start.
The zinc-coated exterior is adequate marine protection, not marine-grade stainless. Rinse it after salt water launches and keep it out of standing water on the ramp.
Where top-wind earns its place
Low-clearance routes. If your trailer has to cross a boat ramp approach with the tongue close to the deck, or you store it in a garage with a low lintel, a flush-retracting top-wind jack solves a problem that side-crank jacks create. Nothing hangs out to clip a curb or a dock edge.
Where it frustrates people
The handle sits on top, which means when the trailer is fully lowered and you are crouched beside the tongue, you are cranking up and over your shoulder. It is awkward in a way a side crank never is. Owners who like the design learn to work it standing rather than kneeling.
At 12 lb it is not a light lift into a high tongue either. And without included hardware, first-time installers face an extra trip to the parts counter.
7. CURT 28115 Marine Jack – Best Big-Wheel Rolling
- 1500 lb lift and support rating
- 8 inch wheel rolls easily over docks and uneven ground
- Zinc-plated steel for salt water and road salt
- Swivels up clear of the trailer
- Limited lifetime warranty on the body
- 18 lb of steel to lift onto a high tongue
- Costs more than the 1200 lb CURT for a similar design
- Mounting rails can bow if installed vertically
This is the CURT to buy if you push your trailer by hand. The 8 inch wheel is substantially larger than the 6 inch wheel on the 28112 and rolls noticeably better over docks, sand and uneven ground. Owners upgrading from a smaller-capacity jack specifically call out the rolling difference as the reason to spend more.
Capacity is 1,500 lb for both lift and support, and the same 3/8-16 x 4 inch hardware fits 2×2 through 3×5 inch frames. Travel is 11 inches, from 13 inches retracted to 24 inches extended through the side-wind handle. The swivel bracket with a heavy-duty pull pin clears the trailer for towing.
The zinc-plated finish is specified against water, dirt and road salt, and the limited lifetime warranty on the body is the feature owners cite when they decide between this and a cheaper import. Combined, those two things make it a sensible long-term purchase rather than a consumable.
Wheel diameter changes how a jack behaves on soft ground more than people expect. A larger wheel bridges ruts and low spots that stop a small caster dead, and it does not sink as quickly into wet sand at the top of a ramp.
Is 1500 lb the right middle ground?
For most dual-axle boat trailers this is the sweet spot. Tongue weight on a 4,000 lb loaded trailer sits around 400 to 600 lb, so a 1,500 lb rating gives you two to three times the load you actually place on the jack. That margin is what lets you crank a half-loaded boat without wondering whether the gear teeth are coping.
Going above 2,000 lb mostly adds weight you tow around for no benefit. Going below 1,000 lb leaves very little room if the boat is heavier than you estimate.
The tradeoffs to accept
At 18 lb it is heavier than the 1,200 lb model in this pair, and the extra steel is not free when you are lifting it onto a high tongue. It also costs more than that smaller CURT for a very similar design, which makes the wheel the deciding factor rather than anything else.
Install it the same way as the 28112, with the bracket groove vertical on thick tongues, to keep the mounting rails from bowing.
8. BIG RED 1000lb Swivel Jack – Best for Light Trailers
BIG RED Boat Trailer Jack with Wheel, 1000 lbs Swivel Boat Trailer Jack
- PP tire resists punctures and sinking on rough ground
- Swivels up parallel to the tongue
- Bolt-on or weld-on mounting
- Includes all parts and a user manual
- Detachable handle for manual cranking
- 1000 lb rating only
- Same locking-pin design complaints as the Torin jack
- One year limited warranty
- Some owners report faster surface rust
This shares its underlying single-wheel design with the 1,000 lb Torin jack, and the reviews read the same way. It is a solid budget replacement for light trailers, and the recurring compliments are about the wheel and the packaging rather than the steel.
The PP tire is specified with a large contact area that resists sinking in mud, gravel and sharp rocks, which makes it better on rough ground than a small hard caster. It bolts on or welds on, and the swivel function lets it fold up parallel to the tongue.
Two things put it slightly ahead of the equivalent budget jack. Assembly instructions come in the box, and the crank handle is detachable, so it stows flat and you are not carrying a bent handle to the ramp as a spare.
Coating is galvanized inner and outer tubes with a powder finish, carbon steel construction. Some owners in coastal areas report the finish rusting sooner than they hoped. Annual rinsing matters here.
Where a 1000 lb rating is genuinely right
Personal watercraft trailers, small aluminium fishing boats and lightweight utility trailers all fall well under the rating. Tongue weight on those is usually in the low hundreds of pounds, so the jack lifts easily and the gear never sees anything close to its limit.
The warranty is one year limited, which is the shortest commitment on this list. Treat it as a consumable part and budget for a replacement every few seasons if you are in salt water.
When you should move up a size
The locking-pin design draws the same complaints as the Torin, including looseness in the swivel bracket. If your trailer is light, that is tolerable. If it is heavy, the pin is the part that decides whether the jack stays put.
Any dual-axle boat over about 3,000 lb loaded deserves a 2000 lb jack, and a 2000 lb jack with dual wheels makes pushing the trailer uphill dramatically easier.
9. TOWKING 2000lb Oversized Wheel Jack – Best for Gravel and Sand Ramps
TOWKING 2000 lbs Boat Trailer Jack, 8″ Widened Trailer Jack Wheel, 13″ Lift
- Oversized 8 x 4 inch wheel for stability on rough ground
- Dacromet anti-corrosion process on crank and bolts
- Handle strap keeps the crank off the ground
- 2000 lb capacity suits mid-size boats and pontoons
- Black powder coat over zinc-plated steel
- Costs more than the other 2000 lb jacks in this group
- 13 inch travel is less than most 2000 lb jacks
- Heavy unit makes installation a two-person job
The wheel is the reason this one exists. At 8 x 4 inches it is wider than a standard 6 inch jack wheel, and owners say it rolls reliably over gravel, sand and soft dirt where smaller casters dig in and stop. If your launch site is ungraded gravel or a beach ramp, this is the jack to shortlist.
Capacity is 2,000 lb, which covers mid-sized boats and pontoon trailers on frames up to 3 x 5 inches. Vertical travel is 13 inches, from 13 inches retracted to 26 inches extended.
The hardware is where this separates from the other 2000 lb jacks. The crank, springs and bolts use the Dacromet anti-corrosion process, which the manufacturer describes as dozens of times better than traditional zinc plating. That is the coating to look for if you launch in salt water regularly and do not want to think about the jack for a few years.
A handle strap keeps the crank from contacting the ground while the jack is laid horizontal, and the unit is manufactured to SAE International standards, which matters more than it sounds if you ever need a replacement part with the same geometry.
Is the wide wheel worth the extra weight?
On gravel, sand and soft ground, yes. On a paved, flat driveway, you are carrying roughly 23 lb of steel and polypropylene for a benefit you will never feel.
Buyers who have used it rate it solidly, with the oversized wheel credited almost every time. The complaints cluster on cost and on the fact that 13 inches of travel is modest for a 2000 lb jack in this bracket. That combination of a wide wheel and a shorter throw is why we do not rank it first overall, despite the strongest coating here.
Before you commit
Check who is doing the install. At this weight, some owners describe it as a two-person job on a high tongue. If you are fitting it alone, budget the time and a set of jack stands for support.
Pairing the Dacromet hardware with our boat trailer tire picks makes sense if the whole rig is going into salt water, since tires are usually the first thing to fail there.
10. Bastion 1000lb Stainless Swivel Jack – Best for Jet Ski Trailers
- Smooth 1:1 side-wind gearing makes cranking predictable
- Stainless steel resists outdoor corrosion
- Swivel mount folds away for storage and towing
- Adjusts across a 10 inch range
- Roughly 14 lb is easy to lift onto a low tongue
- Smallest review base in this roundup with 123 ratings
- Only a 6 month manufacturer warranty
- 1000 lb rating is limited for larger boats
- Mixed plastic and stainless construction
This is a purpose-built marine jack rather than a general utility jack, and the listing names jet ski, boat and marine trailers explicitly. At 1,000 lb capacity with stainless steel construction and a 6 inch wheel, it is sized for personal watercraft and small boat trailers, not for heavy displacement hulls.
The gearing is the detail that stands out. The side-wind crank runs a 1:1 gear ratio, which produces a smooth, predictable feel with a predictable amount of turn per inch of travel. Reviewers comment on how easy it is to crank, and that matters when you are raising and lowering a small trailer several times a day.
Height adjusts from 10.5 to 20.5 inches, which covers tongues between 3 and 5 inches. The swivel mount folds the jack away for storage and transport, and stainless steel handles outdoor exposure better than painted or basic zinc finishes.
At about 14 lb, it is one of the lighter 1000 lb options, which makes it easier to fit onto a low tongue without a second pair of hands.
Is stainless the right coating for you?
Stainless is the low-maintenance end of the coating spectrum. You do not need to baby it the way you do a zinc-plated jack, and it holds up better to salt spray and standing water. The tradeoff is that this listing mixes heavy-duty plastic components with the stainless body, so the wheel and internal parts still age faster than the frame.
If your boat lives in salt water and you would rather not think about the jack, this construction suits you. If you want the whole assembly in one material, look at the zinc-plated CURT models instead.
What the smaller numbers mean
With 123 ratings, there is less long-term feedback here than anywhere else in this roundup, and the warranty runs six months. Both are reasons to buy from a seller with a straightforward return process if you are unsure.
For anything larger than a small boat or a jet ski rig, step up to a 1200 lb or 1500 lb model rather than pushing this one.
11. TOWKING 2000lb 10 Inch Lift Jack – Best for Maintenance-First Owners
TOWKING 2000 lbs Upgraded Boat Trailer Jack, 10″ Lift, Utility Trailer Jack
- Upgraded PP wheel with a reinforced spoke axle
- Powder-coated finish holds up outdoors
- Grease fitting lets you service the moving parts
- Handle strap secures the crank in transit
- Hardware and manual included for 3 x 5 inch frames
- Only 10 inch of vertical travel
- 18 lb to lift into place on a high tongue
- One year manufacturer warranty
This is the jack we would pick if we intended to keep it for a decade and service it as we went. A grease fitting on the moving parts is a small addition, but it is the one most budget jacks leave out, and it is exactly what keeps a side-wind gearbox moving smoothly after a few salt seasons.
Capacity is 2,000 lb for medium to large boats, and the movement range is 10 inches, from 12 inches retracted to 22 inches extended. The construction is high-strength steel with a powder-coated finish, manufactured to SAE International standards.
The wheel is the upgrade worth noting. It uses a reinforced spoke axle, which is the specific fix for the failure owners report on earlier versions, where the wheel deformed or cracked under a loaded tongue. Reviewers treat the reinforced axle as the meaningful step up.
Mounting hardware and a user manual are included for 3 x 5 inch frames, so unlike some top-wind designs you are not ordering fasteners separately before you can start.
A handle strap keeps the crank from touching the ground while towing, which stops the bent-handle problem that plagues cheaper side-wind jacks.
What a grease fitting actually buys you
Salt water and sand do the same thing to a jack gearbox: they get into the threads and the bushing, dry out, and then the crank starts grinding. A grease fitting lets you pump fresh grease into the moving parts once or twice a season, which costs a minute and a grease gun and keeps the threads clean.
Combined with the powder coat, this is the maintenance story of the roundup. If you are the type to hose the tongue down after every launch, this jack rewards it. If you are not, pick a stainless construction instead and let the material do the work.
Where it falls short
Ten inches of travel is short for a 2000 lb jack. If your tongue is tall or you need a wide range to match different hitch heights, look at a design with 12 to 13 inches of adjustment instead.
At 18 lb it is heavier than the smaller TOWKING unit, and the warranty is one year. The greasable design is what makes up for that.
12. TOWKING 1500lb Spoke Wheel Jack – Best Mid-Capacity Pick
TOWKING Upgraded Spoke Wheel Trailer Jack, 10″ Vertical Movement, 1500 lbs, for RV, Boat, Trailer and More, Black, Silver
- 1500 lb capacity is a useful middle ground
- Spoke wheel steers flexibly
- Mounting hardware included for 3 x 5 inch frames
- Zinc-plated steel with silver powder coat
- Handle strap keeps the crank off the ground
- Some owners report the spoke wheel not turning freely
- Handle strap reported loose or missing in some units
- Heaviest-feeling unit in the mid-capacity group
- One year warranty only
This fills the gap between the 1000 lb budget class and the 2000 lb heavy class. At 1,500 lb capacity with a spoke wheel, it suits mid-size boats where you want more headroom than a 1000 lb jack but do not need to carry 20 lb of steel.
The spoke wheel is the visual and handling upgrade over a plain caster. Reviewers find it steers flexibly and looks sturdier, and it carries a zinc-plated steel body under a silver powder coating for corrosion resistance. Mounting hardware for 3 x 5 inch frames is included.
Movement is 10 inches, from 13 inches retracted to 23 inches extended, and the handle strap is meant to keep the crank off the ground when the jack is laid horizontally.
Two complaints come up consistently. Several owners report the spoke wheel not turning freely, including one detailed account of a wheel that would not roll on a 500 lb trailer. If the wheel binds, check that the axle nut is fully tightened before returning anything, because that is the first thing that causes it.
The handle strap is the other recurring issue, with owners finding it too loose or missing in the box. It is a minor convenience item, but if your crank drags on the ground it is worth knowing before you buy.
When 1500 lb is the right number
A dual-axle trailer running 3,000 to 4,500 lb loaded produces tongue weight in the 400 to 600 lb range. A 1,500 lb rating leaves two to three times margin, which is what you want if you also use the jack to level the trailer on a sloped driveway or hold it steady while you change a tire.
Going to 2000 lb adds capacity you will probably never use and more steel to lift. Going down to 1000 lb removes the margin. For most mid-size boats, 1500 lb is the correct middle.
What to check before you commit
Spin the wheel by hand before you install it. If it binds, tighten the axle hardware. Confirm the strap is in the box, and keep the one year warranty in mind if you are installing it yourself for the first time.
Weigh it against the CURT 28115 if you push your trailer a long way by hand, because the 8 inch wheel on the CURT rolls over uneven ground more easily than this spoke design.
How to Size a Boat Trailer Jack by Tongue Weight?
Tongue weight is the share of your loaded trailer weight that sits over the coupler, and for a typical boat trailer it falls between 10 and 15 percent of the fully loaded weight. The jack carries that load every time you hitch, launch or level the trailer.
Worked example. A tandem-axle boat trailer with a 2,200 lb dry weight plus a 1,800 lb boat comes out around 4,000 lb loaded. Multiply by 10 percent and you get 400 lb; multiply by 15 percent and you get 600 lb. A 1,000 lb jack covers that, but only just at the top of the range, which is why most owners of loaded boats move up to 1,200 or 1,500 lb.
Here is how to get your own number instead of guessing. Find your trailer’s GVWR on the VIN plate or the frame rail, subtract what the boat itself weighs, and you have the loaded trailer weight. Then multiply by 0.15 for a safe planning figure. If you tow with full fuel tanks and several passengers every trip, plan at the higher end.
Do not size by lift capacity alone. Lift capacity is how much the jack can raise; support capacity is how much it can hold once it is under load. They are different numbers and they are not always the same, so look for a jack that states both. The CURT models here publish 1,200 lb and 1,500 lb for both lift and support, and the top-wind jack publishes 2,000 lb lift against 3,000 lb support.
If you want to weigh the tongue directly rather than calculate it, a tongue weight scale or a bathroom scale under the coupler gives you the real number in a minute. That measurement is worth repeating after you have a full tank and passengers aboard, since that is when the jack actually works hardest.
Sidewind vs Topwind Drive Explained
Sidewind means the crank handle is mounted on the side of the jack and turns horizontally, like a faucet handle. Topwind means the handle sits on top and turns vertically, like a jack stand. Most budget jacks are sidewind, and the top-wind layout is the reason one design in this roundup costs more.
A sidewind crank is comfortable when the tongue is low, because your hand sweeps horizontally at floor level. The tradeoff is that the handle sticks out beside the trailer, where it can catch a curb, a dock edge or the trailer frame itself when the jack is folded up.
A topwind crank keeps everything above the tube and parallel to the trailer, so nothing protrudes. That is why top-wind jacks retract flush and give better ground clearance in transit. You pay for that with a slightly awkward cranking position when the trailer is fully lowered.
Either drive type will lift the same load. Choose sidewind for everyday cranking comfort on low trailers, and topwind for clearance on routes with tight approaches.
Bolt-On vs Weld-On Mounting and the Sandwich Plate
A bolt-on jack uses a bracket that clamps to the tongue and is held with bolts through the frame, usually 3/8-16 hardware. It is the right choice for a trailer you own and want to service in a driveway with hand tools, and most of the jacks in this roundup are bolt-on.
A weld-on jack mounts permanently and is the right choice for a new trailer build or a boat you rebuild every few seasons. Two of the units here accept either method, which is useful if you might move the jack to a second trailer later.
If your tongue is thin steel, add a sandwich plate, sometimes called a doubler plate. It is a second plate bolted or welded on the inside of the tongue to spread the load across a wider area so the bracket does not crush or tear the metal. On a 2 inch tongue carrying a loaded boat, this is the difference between a mount that stays square and one that pinches closed.
Two mounting mistakes cause most of the complaints we saw. First, bracket orientation on a thick tongue, where the groove must run vertically or the mounting rails bow. Second, mixing up hole positions on a bracket that looks symmetric but is not. Check the hole pattern against your tongue before the final bolt.
Galvanized, Clear Zinc, Stainless and Saltwater Survival
Galvanized steel has a zinc coating that protects the base metal and also looks like part of the finish. It is the common marine choice and it works well if you rinse the jack with fresh water after every trip in salt water.
Clear zinc and zinc plating are thinner coatings with a brighter finish. They handle road salt and freshwater exposure adequately, and several owners of zinc-plated jacks report multi-year service when maintenance is done. They are the first thing to bloom with surface rust if you leave the jack wet.
Stainless steel needs the least attention of the three. It resists corrosion without painting or coating, which makes it the sensible pick for a boat that sits in a brackish estuary or gets launched weekly in salt water.
Dacromet is a heavier treatment applied to hardware pieces, and it outlasts ordinary zinc plating by a wide margin on bolts, springs and cranks. It is the detail that separates the best-coated jack in this roundup from the rest.
Powder coating sits on top of zinc plating and adds a barrier layer plus a finished look. It works well but can be chipped at mounting points, and once a chip opens, rust starts under it.
Whichever you pick, the maintenance routine is the same. Rinse the whole jack with fresh water after a salt launch, dry the threads, and grease the gearbox if the jack has a fitting. For those without a fitting, a light coat of marine grease on the screw threads twice a year keeps the nut from welding itself to the tube.
Wheels, Drop Legs and Stability on Soft Ground
A wheeled jack lets you roll the trailer into position by hand, which is what you want at a ramp when you are alone. A single small caster digs into gravel and wet sand, so dual wheels or a larger wheel diameter makes a real difference on rough ground.
A fixed foot is more stable than a wheel under load because the base does not roll. A drop leg goes further, giving you a second ground contact point that stops the tongue bouncing while the trailer is parked. The top-wind jack in this roundup has a 12 inch drop leg that you pull out before you fine-tune height with the crank.
The tradeoff is manoeuvrability. A drop leg has to be retracted before you move the trailer, and a fixed foot means you cannot roll it at all. For a boat that lives on a trailer in a marina, the extra stability is worth it. For a trailer you move every weekend, wheels are simpler.
Ground clearance in transit is a separate question from stability while parked. Check that the jack retracts fully and, if it does not fold up, check that the retracted height clears your lowest ramp approach. A jack that cannot fully retract is one of the most common complaints forum owners raise.
Never work under a trailer that is supported only by the tongue jack. Use wheel chocks on the drive wheels and place rated jack stands under the frame before you go underneath.
Electric vs Manual Jacks for Boats
A manual crank jack has no power source, nothing to wire and nothing to fail. It works on any trailer, including one stored far from the truck, and a new owner can service it with basic tools. For most boat trailers, manual remains the sensible default.
An electric jack runs off trailer battery power through the 7-way connector and raises the tongue with a button. It is genuinely worth it on a heavy tandem-axle boat, where cranking a loaded tongue takes real effort every time. We have written up the best electric trailer jacks separately if you want the wiring detail.
The tradeoffs are real. Electric jacks need a healthy battery and a sound 7-way connector, they cost more, and a dead battery at a ramp is a bad morning. Look for a model with a manual backup crank, because the ones without it have a way of stranding you.
Salt water is harder on electric units than on manual ones because the motor housing, the switch and the wiring are all extra places for water to sit. If you launch in salt and want electric, plan on rinsing the unit down as carefully as you rinse the rest of the tongue.
For a PWC trailer or a small fishing boat, the manual crank on the top picks will be faster than waiting for a battery to charge. For a 5,000 lb tandem-axle boat, electric earns its place.
How to Free Up a Stuck or Frozen Trailer Jack
A jack that will not move is usually one of three things: a seized gearbox, a rusted or cross-threaded screw, or a bracket that is loaded with the weight of the trailer. Start by taking the weight off it before you touch the crank.
Unload the jack. Raise the tongue slightly with the hitch or a floor jack so the trailer weight comes off the jack foot, and chock the wheels. Cranking against a loaded tongue is the most common reason a jack seems seized.
Back the crank off. If it went up but will not come down, turn the handle a quarter turn past the point where it stopped and apply steady pressure. Cross-threaded screws usually release this way.
Free the screw threads. Spray a penetrating oil into the threads where the inner tube meets the outer tube, wait several minutes, and try again. Repeat the cycle two or three times. Do not use a pipe wrench on the tube.
Work the gearbox gently. With the foot unloaded, rock the crank back and forth in small increments. If it moves a fraction of a turn and then binds again, the gear teeth or the thrust bearing are the problem.
Break the corrosion bond. For a jack that has sat in salt water through winter, a penetrating oil worked into the base of the inner tube and around the pin usually frees it overnight.
Strip and clean. If the crank turns freely but the tube will not move, remove the inner tube, clean both the male and female threads with a wire brush, grease them heavily and reassemble.
Check the swivel pin. If the whole bracket moves loosely or the jack leans, the locking pin is worn or partly pulled. Replace the pin before the next launch rather than discovering the problem at a ramp.
If the gearbox is genuinely stripped, replacement is usually cheaper than repair. That is the practical argument for buying a jack with a documented warranty and a stated capacity, which is why the CURT models rank where they do in this roundup.
Frequently Asked Questions
Are Harbor Freight trailer jacks any good?
Budget-brand trailer jacks including Harbor Freight models tend to use thin steel and a basic zinc finish, so they work fine on a small freshwater trailer that stays reasonably dry. Owners in salt water report replacing them roughly annually because corrosion seizes the gearbox and threads. For coastal use, a zinc-plated or stainless jack with a stated warranty lasts much longer. If you buy the budget option, rinse it with fresh water after every launch and grease the threads twice a year.
What is a good heavy duty trailer jack?
A good heavy duty boat trailer jack is rated at 2,000 lb or more, built from steel tube rather than thin stamped plate, and coated for marine exposure. Look for dual wheels or a wheel at least 8 inches across if you push the trailer by hand, a swivel or drop-leg design for stability, and published lift and support ratings. The units here with 2,000 lb ratings and zinc, powder or Dacromet coatings cover tandem-axle boats up to about 5,000 lb loaded.
Are electric trailer jacks any good?
Electric trailer jacks are worth it on heavy tandem-axle boats where cranking a loaded tongue takes real effort every time. They run off trailer battery power through the 7-way connector, so they need a healthy battery and sound wiring. Choose a model with a manual backup crank, because the ones without it can strand you at a ramp with a flat battery. For small boats and PWC trailers, a manual crank is faster and has nothing to fail.
What are the best trailer jack blocks?
Trailer jack blocks are wooden or plastic chocks that hold a parked trailer securely, and they are not a substitute for a tongue jack. The best blocks are wedge-shaped, sized to your trailer tires, and stored on the tongue so they are always with the trailer. Use them alongside the jack, never in place of wheel chocks when you are working under a trailer. For stability on soft or sloped ground, a drop-leg jack serves the same purpose far more effectively.
What are the best boat trailer jacks?
The best boat trailer jacks depend on tongue weight and water exposure. The Jeremywell 2000lb dual wheel jack is the strongest all-round pick for most boats. The VEVOR 1000lb swivel jack suits small boats and jet ski trailers. The CURT 28112 is the marine-grade choice for coastal water, and the TOWKING 2000lb with an 8 by 4 inch wheel handles gravel and sand ramps best. Size any of them above your loaded tongue weight, which runs 10 to 15 percent of loaded trailer weight.
Why won’t my trailer jack go up or down?
The most common reason is simply that the trailer weight is still on the jack. Raise the tongue slightly with the hitch or a floor jack and chock the wheels before you crank. If the crank turns but the tube will not move, the threads are likely rusted or cross-threaded, and penetrating oil worked into the threads will usually release them after a few cycles. If the crank will not turn at all with the load removed, the gearbox or thrust bearing has failed.
How to free up a stuck trailer jack?
Take the weight off the jack first by raising the tongue and chocking the wheels. Then spray penetrating oil into the threads where the inner tube meets the outer tube and wait several minutes before trying again. Work the crank in small increments rather than forcing it. If it still binds, remove the inner tube and clean both sets of threads with a wire brush, then grease them heavily before reassembly. A jack that is stripped inside usually costs more to fix than to replace.
The Best Boat Trailer Jack for 2026
The best boat trailer jack for most people is the Jeremywell 2000lb dual wheel unit. It has the headroom for a loaded boat, the dual wheels that make a ramp launch manageable alone, and enough review history to trust the number on the label. If your boat is small or your trailer is light, the VEVOR 1000lb swivel jack does the same job with less steel and a full hardware kit in the box.
For coastal water, the CURT 28112 and 28115 are the picks, with zinc plating and a limited lifetime warranty on the body. For gravel and sand ramps, the TOWKING 2000lb with the 8 by 4 inch wheel and Dacromet hardware holds up best. Whichever you choose in 2026, size it above your calculated tongue weight, check the bracket orientation before the final bolt, and rinse it with fresh water after every salt launch.
