Product Details

The TotalBoat Trailer-Mounted Boat Lift is a safe, stress-free way to raise a boat weighing up to 10,000 pounds up to 12" above the bunks or rollers, by yourself. Do routine maintenance with your boat still securely attached to the trailer.

This simple but ingenious system uses four lifts attached to your trailer and positioned under the four strongest areas of the boat: hull chines, stringers, and transom. While raising the boat, it's easy to keep the load balanced by turning the adjustable rod on each lift one half turn at a time. As your boat lifts up off of the trailer, it remains stable and secure because the lifts are attached firmly to the trailer itself.

Sturdy, adjustable lifts are available in two sizes and are extremely easy to configure to accommodate a wide range of boat shapes and sizes. No more hoists or dangerous improvised solutions! See the Tech Specs tab and the Info & Guides tab for dimensions and fit information that will help you select the right lift for your boat and trailer.

Info & Guides
Important Fit Requirements

The Trailer-Mounted Boat Lift System requires minimum clearance heights where each lift is mounted:

Make sure there is a minimum of 12" clearance from the ground to the bottom of your trailer frame. Additionally, the distance from the top of the trailer frame to the chines must be no less than 10".

Boats with very low trailers and or low rise from the trailer to the boat may lack sufficient clearance.

This innovative lift is available in two sizes: The Trailer Boat Lift System (TB-BLT4) is designed for use on trailer beams 2" to 3" wide and 4.5" to 5.75" tall. The XL Trailer Boat Lift System (TB-BLT4XL) is for trailer beams that are 3" to 4.625" wide and up to 10" high.

Please inquire if you have any questions.

By Bob Bradley from Middletown Delaware.

I'm a believer if you want something done do it yourself. The trailer lifts worked great minimal modification my trailer frame depth was only 4" installed 1/2" metal spacers under bottom plate then washer & nut, easy assembling. Bottom painted on Saturday morning boat in water Monday morning.

Bottom Line Yes, I would recommend to a friend

Worked for me
By Power engineer from Indiana

This worked well for my retracting keel sailboat. I sent pictures to Brownell first as a safety check. Just to be sure, I also made some captive anti-slip, plywood and rubber covers with greater surface area. Very happy with the results.

Bottom Line Yes, I would recommend to a friend

I would use different jacks for the transom
By Gary from Occidental Ca.

Verified Purchase

I have a 21foot Whaler. The size of boat on a older trailer did not work well. I had to remove the bunks to paint.

Works well with some modification.
By Rob from NY/CT

I didn't read the specs carefully that states "the lift is designed for use on trailer beams 2" to 3" wide and 4.5" to 5.75" tall." Most small trailer frames are 3x4 as was mine. The supplied 9" bolts were too long so I ended up getting new bolts that were 8". Then the manufacturing process was sloppy, the holes in the plates were a little less than 3" apart and would not fit around my 3" frame. I called and they quickly sent me new plates that were drilled properly. Once these issues were addressed they worked well, my GW 180 is about a foot off the bunks for painting and bunk replacement. And everyone else is correct about the paint on the lifts, it was flaking off from shipping.

Bottom Line Yes, I would recommend to a friend

Great product
By 21' Regulator from Boston, MA

Bought this for use on my 21' Regulator. Worked well for bottom painting and would definitely recommend it. Pros: - Got the boat up in air - Worked in tight space (boat doesn't have much overhang outside of trailer) where traditional stands would not fit in - Easy to use / install (though an impact wrench helps with the install on the hex nuts) Couple of quick "product" comments: - Would be nice if it were available galvanized - The trailer attachments were wrong size for my trailer, so I had to add a 2x4 as buffer to get the whole setup in place - It's definitely a workout to get the boat lifted up in the air with this Other: - Make sure that you can slide under your trailer! You still need to be able to reach all those tough spots - this will create some clearance but your boat is not going to be way, way up in the air...it's still relatively close to the ground and you're going to be working on your back to get the job done Definitely would recommend. Nice, innovative system that could probably use some improvements on the plating system (how it attaches to the trailer).

Bottom Line Yes, I would recommend to a friend

Working great for my bottom paint job
By Mysticmako from Palm Beach FL.

Verified Purchase

The trailer lift system is allowing me to prep, prime and paint the entire bottom of my 20' center console boat. Based on another reviewer with a similar EZ Loader trailer I decided to buy the lift system. As the other reviewer mentioned I bought a box of 50 washers so I could add 4 washers to each bolt so the nut didn't reach the end of the by thread. The beams on my trailer are about 2.5" high so it almost worked without the washers. Fortunately the width of the trailer beams (3.5") allowed for a good (but tight) fit so I didn't have to modify or replace the included brackets as some have mentioned. Also, the space between the top of the trailer and the boat transom is about 8" so that made for a very tight fit for the aft jacks. After maxing out the jacks at the bow I ended up with about 8" of space between the bottom of the hull and bunks which is enough room to use my orbital sander on all areas of the hull. Working around the trailer structure isn't always easy but I was able to reach everything one way or another.

Bottom Line Yes, I would recommend to a friend

Could use improvement
By VeeJay from New Jersey

This would be an awesome product if the plates were an inch longer to fit many of the trailers that have 3 1/2" beams. The cost to modify the plates for a work around starts to make it not worth it. Seems to me it would be only a slight change in the manufacturing that would have minimal additional cost and make it appeal to many more buyers.

Bottom Line Yes, I would recommend to a friend

Works as advertised
By Paul from East Moriches, NY

Verified Purchase

Does what it decribes. Paint is a little thin, but that's no what you buy them for. They lift he boat safely and allow you to work under it while still on the trailer. Trailer will still be under the boat and you'll have to work around it, but everything is accessible.

Bottom Line Yes, I would recommend to a friend
