It is the gear plates that form the foundation of a flat-plate boat hoist. At the top of the plate, where the drive pipe is installed, there is a 96-tooth worm gear. Below is a smaller worm gear with a stem for the hoist pulley. Mounting holes on the gear plate allow an electric motor with a 56-frame to be mounted. Install a pulley on both the motor and the stem of the smaller worm gear and then install a belt to turn the gears. A 96-tooth worm gear is turned by this movement, which then turns the boat lift's drive pipe.
