HOOKER IMPELLER FOR YAMAHA 144MM
The New Impros Hooker 144mm impeller for the Yamaha is a 3 blade large hub diameter, radial edge design polished stainless steel impeller designed and intended for Bottom end and "Hook up" for freestyle and freeriders on a Superjet, Blaster, or similar ski that utilizes the 144mm 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 a new radial edge design, large hub (75mm), and is set back 7mm (4mm further than we can go with a small hub impeller).
It is a highly polished Yamaha impeller that we will have available for the 144mm stock pump, and 144/142/140mm Magnum pump. Designed with a steep root angle to load the pump well. Material is a 17-4 stainless steel cast. Dynamically balanced, and comes mirror polished, with an impeller tool and rubber nose seal. We have it available in a variety of pitches for different engine set ups. The pitches available are 9/15, 10/16 and 11/17. These numbers are much different from other impeller pitches you have heard of. While they are very low, and directed at bottom end "Hit", the root angle, blade length and other geometric differences set the Hooker apart from the others. We also produce "more aggressive" custom pitch Hookers for engines that require it, for an additional charge. 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. We're excited about how this impeller works compared to the other popular repitched impeller versions that have become so popular. Please don't misunderstand, they work very well, this one just works better, and gives the ski more "pop". As stated above, they fit in the stock 144mm Yamaha pump, Solas 12 vane 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. Want peace of mind with your purchase?
