Impros Yamaha NEW SJ Hooker Impeller (SKU: IMY4SJ144)

Description

The *ORIGINAL* Impros Hooker impeller for the newer Yamaha Super Jet models! Set back, and a large hub design that works with the newly designed stock 144mm pump that comes on the 2021 Superjet.

The Impros Hooker impeller was made specifically for the 2021-2023 Yamaha Super Jets is a 3-blade large hub diameter, radial edge design stainless steel impeller designed to improve the overall performance of your ski. We gave it this name because it “hooks up” so well.

Dynamically balanced, comes with our recreation polish, and a rubber nose seal.

We have it available in a variety of pitches for different engine set ups. These numbers are much different from other impeller pitches. We offer the 11/17 pitch for stock skis, and if you have a tune, we suggest the 10/16 pitch. We even offer our low pitched 9/15 for certain tunes, and for higher elevation riding. To produce “more aggressive” choose a custom pitch for engines that require it, for an additional charge.

We recommend also buying a WR001 impeller tool as well, for ease of installation.
