New Impeller for Yamaha SJ/Blaster 144mm pump We call her the "Hooker" because she "hooks up" so well. Designed around maximizing pump efficiency and bottom end, this is a new radial edge design, large hub (75mm), and is set back 7mm (4mm further than we can go with a small hub impeller).

Pitch options are:
9/15 (for anything from a stock 701 to a strong limited set up) 10/16 (for the more healthy version of a limited with porting, big carbs, etc) 11/17 (for maximum hook up and added HP)
Designed with a nice steep root angle to load the pump well. Some might say they sound too low and may spin, or burn outta the hole, but the other geometric changes made to the Hooker reduce the chance of spinning.
They are designed for Freestyle, and Freeriding, although some of our riders are using them for closed course racing as well with great results. To give you an idea of the load on the engine, the 9/15 loads similar to the custom Solas 13/15 that we do. Further set-back increases the pump efficiency, along with the larger hub and blade length. Comes with an impeller tool and nose seal.
