ABSTRACT:
A three-phase drive motor is utilized to operate a boat lift. In one example, a drive motor arrangement for replacing manual drives on an existing boat lift winch shaft comprises a worm gear box with a worm driven by an integrally mounted motor on the worm gear box. A worm gear is mounted on a tubular cross shaft extending outwardly on opposite ends of the gear box. The bore of the cross shaft is of size to slide over an existing winch drive shaft. The tubular shaft has a drive connection that mates with the existing drive connection on the winch box shaft. As shown a disc that effects drives to a mating disc on the winch box shaft. After removing the manual ratchet and wheel on an existing winch shaft, the tubular shaft of the worm gear box can be put into place and a suitable fastener is used to hold the drive connection on the tubular shaft in engagement with the drive member on the winch shaft.
