An attachment for a boat lift to facilitate its placement and/or removal from a dockside location. A boat lift for small pleasure boats generally comprises a stationary framework which supports a movable boat supporting member and a winch or equivalent mechanism for elevating and lowering the boat supporting member relative to the stationary framework. The present invention comprises a set of wheels which are mounted on the stationary frame and normally retracted when it is desired that the boat lift rest upon the lake bottom or on shore. When it is desired to reposition the boat lift itself, a coupling is established between the wheel assembly and the boat supporting member so that when the boat lift's own winch mechanism is operated, the wheels are extended causing the weight of the boat lift to be supported on the wheels rather than upon the ground.
