Golden Boat Lifts® has the finest drive unit ever introduced for a boat lift system. The “SEA-Drive” is an Aluminum Die-Cast Enclosure, Housing Dual Worm Gear Reducers. This configuration assures that the gear box will never back drive. We do not use electric brakes, as even the best electric brakes fail in a harsh waterfront environment. Our system connects the Sea-Drive directly to the boat lift drive shaft with an over sized 5/8″ hardened drive pin. This is needed due to the high output torque the Sea-Drive produces.
