Good To Know

Q: Will this housing fit my Wave Runner III 700? A: It is listed for 1994, 1995, and 1997 model years, but you should confirm the part number 6R8-51312-03-94 matches your machine before ordering.

Q: Do I need any additional parts when replacing the housing? A: A wear ring, seals, and hardware are typically replaced at the same time, so inspect those components while the pump is apart.
