I'm looking for suggestions on a new impeller. I have the stock but it almost feels like it is blowing it out. It just seems like it should have more. I'm being told a 12/17. Isn't stock 13/18. I would have thought with the mods the pitches would go up. Like 14/19. Scattrack shows 14/19 Here is what I have.

800sxr
Vforce reeds
Tau cetti air filters
Scoop grate
Pump shoe
Ada head running 93 octane psi should be 180+
Factory wet pipe
Tdr waterbox
Dual exhaust out.

General freeride and surf. Let me know what you think would be a good impeller upgrade from stock.

 

The stock prop is a good impeller. If you are wanting to change Look into the Skat 9/17 Swirl .I have this on one of our lites boats It is a little faster than the stock prop and has more bottom hit. Solas 13/21 is a good option also, I have this one on a 850 lites boat Little more top speed than the Skat and not quite so abrupt on the throttle response.
