Specs At A Glance

Good To Know

Q: Should the wear ring be replaced with this housing? A: Checking the wear ring any time the pump is removed is advised, because a worn ring cuts thrust and can wear a new housing bore prematurely.

Q: Is this an original Yamaha part? A: No, this is an aftermarket replacement jet pump housing made for Yamaha applications and is not an original brand product.

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