Good To Know

Q: Does this housing come with the impeller or wear ring? A: No, this listing covers the jet pump housing only, so the impeller, wear ring, and bearings are ordered separately. Reuse your existing internal parts if they are still within spec.

Q: Will this fit every GP 1200? A: It is listed for the 1997 through 1999 Yamaha GP 1200, but pump setups can vary by serial number. Compare your original part number against 65A-R1312-00-00 before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
