The Impros Hooker 140mm impeller for 2-stroke Kawasaki application. The impeller is 140mm outer diameter, 75mm hub size. Ditch you stock impeller that creates so much cavitation. You'll be amazed at the performance gain with this impeller upgrade.
In a world where it seems most people engine and pump swap their Kawi's, it is CRUCIAL that you know if your Kawasaki is running a 750/800 model 140mm pump OR a 650cc model 140mm pump, Although both are 140mm diameter - they require a slightly different machined impeller.
Includes rubber nose seal. Highly recommend adding an impeller tool (WR001) as well, for ease of installation.
The pitches available are 9/15, 10/16, 11/17 and 12/18. These numbers are much different from other impeller pitches you have heard of. These numbers are much different from other impeller pitches you have heard of. While they are very low, the root angle, blade length and other geometric differences set the Hooker apart from the others. THIS IS NOT A STOCKED PART, 2-3 DAY ARRIVAL TO HSI ONCE YOU ORDER. If you need a custom pitch for your application, we can special order it - depending on time of year ETA will be 2-4 weeks.
The hooker impeller features a proprietary 3-blade radial-edge design with a large 75mm hub, the Hooker is engineered to maximize pump efficiency and keep the pump loaded during aggressive riding. Includes radial edge design stainless steel impeller. Material is a 17-4 stainless steel cast with recreation polish. Will fit into many aftermarket pumps like Solas, Skat-Trak, Freedom, and SBT.
Description of LEADING vs TRAILING edge pitch: The leading edge is the blade that is first in contact with the water entering the pump tunnel before it gets pushed through the pump. This is your right-off-throttle "bottom end" hit. The trailing edge is what will carry you through the power band and allow the engine to get the full amount of power to the water. People often don't realize it, but impeller tuning is just as important, if not more, than carburetor tuning.
