Good To Know

Q: How do I know this housing fits my craft? A: It is built for the Yamaha GP-R 1300 from 2003 through 2008. Confirming your model year and pump layout before ordering is recommended.

Q: Can I reuse my existing pump internals? A: In many cases the impeller and wear components can be moved over if they are still within spec. Inspect them for wear while the pump is apart.

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