Skat-Trak Yamaha WR/WJ 500 Impeller

The WR/WJ 500 impeller is a stainless steel 3-Blade impeller, and is much more efficient than the stock aluminum impellers that come with the 500 and 650 LX model WaveRunners.

This design is very effective at reducing cavitation, provides a top speed gain while increasing bottom end acceleration as well. It’s simply one of the most noticeable increases you can do to these PWC for the least amount of money spent.

The WR/WJ 500 impeller fits into the mixed flow pump used specifically in the Waverunner 500, and 650 LX models only.

We recommend also buying a Driveshaft holding tool as well, for ease of installation.

We will custom pitch your impeller to meet your needs, are you riding at elevation or with a tune, any modifications? Let us know and we’ll pitch it so you’re getting top performance!
