The wiper motor fits and works. It is made by Marinco as part number 34000. Installation requires no modification to the vehicle, but the wiper arm is different. Use Marinco part number 33010A. So, the motor cost $139 and the arm was $31. $170 is a whole lot less than the $440 at the dealer. It is interesting just how many GEM parts are actually Marinco parts used on boats.
