Boat lift floats are large air tanks that can be filled with water to submerge them and then re-floated by evacuating the water with air pressure. All Boat lift floats come with a wall thickness of .375”. Our boat lift floats were designed initially for manufacturers of boat lifts, as a mechanism to raise and lower a lift platform. However, many individuals have used these floats to build their own boat lifts.

Boat Lift Design
Our boat lift floats come in eight different sizes with round and square bottom designs. All come with threaded inserts ready for commercial fittings and a large molded-in hole in the bottom for water intake and exhaust. Molded in mounting slots in the top of each float and molded in grooves make attachment to a boat lift frame easy.
