    New Impros Hooker Impeller

    New Impros Hooker Impeller for Yamaha 144mm pump.

    We've been working on a new impeller for our Freestyle riders on a Yamaha SuperJet and Blaster and came up with this one.

    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)

    Here's a couple amateur shots by me of the new Hooker...

    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. I'm really happy with how this impeller works compared to the other popular repitched versions that have become so popular. Don't get me wrong, they work excellent, this one just works better, and gives the ski more "pop".

    Retail price is $249.99, and comes with an impeller tool and nose seal.

    I bet we start to see some large impellers for us in the near future because of the SHO. I have a feeling those skis are going to start to crank out some huge power.... and with that a huge impeller is needed.

    The problem with this is, the SHO driveshaft is larger diameter than the GPR
