There are 2 basic water pump kits for the V-4 and V-6 JOHNNY-RUDES. They both use the same impeller, but they use 2 different housings. Your 150 should use the later style water pump. They run about $60-$65 for the complete kit at a dealer, or you can pick up an impeller for around $20. You can find them on E-bay or at a dealer. Aftermarket is available as well for the impeller, but I don't think they offer an aftermarket housing for the late model ones.
