ABSTRACT:
A housing for at least partially housing a boat lift pulley of a boat lift includes a main wall having a substantially vertically disposed wall portion defining an inwardly opening generally concave chamber adapted to at least partially receive therein a boat lift pulley. The main wall includes vertical and horizontal planes disposed substantially normal to each other with the concave chamber being offset to one side of the vertical plane. First and second wall portions of the main wall located at opposite sides of the horizontal plane are adapted for selective removal whereby a gear driven shaft can project therethrough to adapt a housing for selective utilization in either of two positions of installation oriented 180.degree. relative to each other. A peripheral edge portion of the main wall preferably includes symmetrically located fasteners for securing the housing to a companion housing in each of the two positions of 180.degree. oriented installation.
