Impros Yamaha Superjet SJ 1050 Hooker Impeller IMY4SJ144

The *ORIGINAL* Impros Hooker impeller for the new Yamaha Super Jet SJ1050 TR1!
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- Yamaha Superjet – it is a 3-blade large hub diameter, radial edge design stainless steel impeller designed to improve the overall performance of your ski.
Impros gave it this name because it “hooks up” so well.

Dynamically balanced, comes with Impros special recreation polish, and a heavy duty rubber nose seal.

Impros have variety of pitches for different engine set ups – These numbers are much different from other impeller pitches.
The 11/17 pitch for stock skis, 10/16 for tuned TR1 engines and the low pitched 9/15 for certain tunes, and for higher elevation riding.
