Question about prop pitch.
Hey everyone, I am trying to an idea on a correct prop pitch for a stock ECU'd RXT-X.
It will have a 4" air intake, Riva Pro supercharger upgrade. I will be running a Solas 15/22R prop. I also have a Riva intake grate installed if that makes a difference.
Conditions are 80's for air temp, high 60's for water temp with lower humidity on average.
Thanks for any help! -Mat-

My RXT-X is set up much like yours with the Riva grate being the exception, I run the R&D Aquavein and sometimes a modified stocker. The best results for my conditions and style of riding were to add 2.5mm to the trailing edge of the 15/22R. The RPM's are consistently 8000-8040 in 95 deg. weather and 80 deg. water temp. The holeshot is good, mid range is strong and top end is acceptable (72 mph). I rarely run in flat water, preferring to search out rough wind blown choppy conditions. If it matters I will be sending my 15/22r to Speedfreeksracing.com for the pitching, truing and setback mod.

Is Erik around>??? I heard he was MIA. If he is around I may just bring the whole ski to him. I would like to get everything in and some what close before that though.
