The New Impros Hooker 144mm impeller for the Yamaha is a 3 blade largehub diameter, radial edge design polished stainless steel impellerdesigned and intended for Bottom end and "Hook up" for freestyle andfreeriders on a Superjet, Blaster, or similar ski that utilizes the144mm pump and want maximum AIR for tricks. 
We gave it this name because it "Hooks Up" so well.
Designed around maximizing pump efficiency and bottom end, this is anew radial edge design, large hub (75mm), and is set back 7mm (4mmfurther than we can go with a small hub impeller). It is a highlypolished Yamaha impeller that we will have available for the 144mmstock pump, and 144/142/140mm Magnum pump. Designed with a steep rootangle to load the pump well. 
Material is a 17-4 stainless steel cast. Dynamically balanced, andcomes mirror polished, with an impeller tool and rubber nose seal.

We have it available in a variety of pitches for different engine setups. The pitches available are 9/15, 10/16 and 11/17. These numbers aremuch different from other impeller pitches you have heard of. Whilethey are very low, and directed at bottom end "Hit", the root angle,blade length and other geometric differences set the Hooker apart fromthe others. We also produce "more aggressive" custom pitch Hookers forengines that require it, for an additional charge.

To give you an idea of the load on the engine, the 9/15 loads similarto the custom Solas 13/15 that we do. Further set-back increases thepump efficiency, along with the larger hub and blade length. We'reexcited about how this impeller works compared to the other popularrepitched impeller versions that have become so popular. Please don'tmisunderstand, they work very well, this one just works better, andgives the ski more "pop".

As stated above, they fit in the stock 144mm Yamaha pump, Skat Trak Magnum pumps (with a shim), and TBM Super Pump Cones.

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