Our boathouse lifts can be installed with one or two electric motors. Hoist load is dependent on the boathouse construction and the weight of the boat. Drive units are side mounted for easy maintenance and elimination of grease dropping on the boat, as with center mounted drives. Overhead beams mount on the top plate along side rafters or directly on top of pilings. Pulleys and drive shaft attachments are welded to overhead beams adding to the level of the quality of the boathouse boat lift.
