Moving a small boat, jet ski, or utility trailer around the driveway or garage doesn’t have to be a strain. The etrailer Boat Trailer Jack w/ Wheel has a 6" caster that swivels a full 360°, letting you steer and position the trailer by hand with ease. The sidewind handle gives you smooth control, and the entire jack swings up and locks in place when it’s time to tow. It’s a simple design that’s heavy-duty where it counts so you can roll your setup exactly where you want it.
Saltwater, rain, and road spray can destroy an unprotected jack in no time, but this one has a clear zinc finish that keeps corrosion in check. It’s made for the realities of boat and recreational trailer use—resisting rust even when stored outdoors. The tough outer tube measures 2" in diameter, with a 1-3/4" inner tube that’s strong and stable under load. It’s the kind of protection that keeps the crank turning smoothly season after season.
Installation doesn’t require welding or modifications. The included clamp-style bracket and mounting hardware bolt right around trailer frames from 2" to 4" tall. Once installed, just pull the spring-loaded pin to swing the jack up for travel or drop it down to lift. With a retracted bracket height of 13-1/2" and an extended height of 23-1/2", you get a 10" of lift to easily level or hitch your trailer.
This manual sidewind jack supports up to 1,000 lbs, giving you solid lifting power for small boat, jet ski, or light utility trailers. The 7" handle radius provides steady cranking leverage, and the smooth-turning bearings make operation easy even under load. Whether you’re swapping out a worn-out factory jack or adding one to a custom setup, this unit delivers dependable performance without the bulk or complication.

My MJ-1206B trailer jack continues to function properly after a year of use and makes moving my trailer easy.

The above fix installation of spacer washers on axle worked. After one year since purchase, the tongue jack has been performing well, without problems. The use has been only occasional since the trailered boat has just now been completed. Tongue weight is light, at about 75 lbs.

Trailer jack wwheel has worked excellent for the last year. I plan to get another one for our cargo trailer which has a post jack that doesnt retract or swivel and drags on low egress or speed bumps. Another one of these swivel wheel jacks will work just perfect. Thanks etrailer
