The Impros 160mm impeller for 2-stroke Yamaha application. The impeller is 160mm outer diameter, 75mm hub size, 20mm threads. Intended for a Super Jet, Wave Blaster, or any other model that has a shaft with 20mm thread and the pump is 160mm in diameter.
Includes impeller tool and rubber nose seal. Highly recommend adding a driveshaft holding tool (WR004H) as well, for ease of installation.
We have listed common pitches that we sell, such as 9/15, 9/17, 10/16, 11/17, 11/19, 12/18, and 12/20. LONG BLADE, THIN BLADE, and CUT BACK option is very good for freestyle skis. 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 A STANDARD PITCH. 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 is a 3-blade large hub diameter, radial edge design stainless steel impeller. Material is a 17-4 stainless steel cast with recreation polish. Will fit into many aftermarket 160mm pumps like Skat-Trak, Torrent, BUN, Pitch, Freedom, etc.
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.
