ABSTRACT:
A boat lift assembly wherein the use of a conventional cable system has been replaced with a screw drive assembly. The screw drive assembly eliminates all the safety hazards which accompany a cable operated system. Additionally, the use of aluminum components is extensive throughout to keep corrosion to a minimum. Further, Teflon and Lexan wear strips are used to eliminate friction problems between the relatively moving members.
