Wsm Yamaha Pump Housing Waverunner, Venture, & Gp'S

Now available an alternative to the OEM impeller housings that are known to warp and dimple. The original Yamaha impeller housing is constructed of cast aluminum with a thin stainless steel wear ring liner that is pressed into place. Corrosion quickly develops between the dissimilar metals swelling the thin liner until it closes down and jams against your impeller. These replacement impeller housings offer a replaceable plastic wear ring (003-521) similar to those found on the Sea Doo watercraft. If the liner becomes damaged you simply remove the old liner and replace it with a new one at a fraction of the cost of a new housing.
