Flat-Plate Hoist Motors are wired electric motors with short control cables. Flat-plate motors are designed specifically for flat-plate boat lifts. In addition to an in-line GFCI and drum switch, these motors can be wired either 110v or 220v. A flat-plate hoist motor is a 56-frame motor. It only works with the flat-plate hoists. The motor mounts directly to the gear plate.
