    Prop Selection Help RXP!!!

    Ok guys I need to know what prop everyone is running with my combo!!! I have 2 customers RXP watercraft set up the same! both are 2005 Sea Doo RXP's, Riva Stage 3 complete, Riva water box, Skat Trak 15/19 3 blade prop, Sea Doo X-charger, Riva X-charger housing and impeller, Riva rear air intake!!! The ski's both run 75.5 on GPS and they are all over the Rev limiter!!! they hit 75 in no time, take off is great!! but not top end. If someone could help with prop selection, would be great!!! Thanks!!! I know it is not often I as for help, but the holiday weekend is here and I dont have time to try prop after prop!!!

    I was doing 63 on the limiter with a rude 1 with my stock ECU RXP. It means nothing. Now I'm at 80.3 MPH with the correct pitch.

    I agree with the 15/22 though. Start with that and if you can't do your own tweak to get around 8500 RPMs then I would send it to Speedfreeks Racing for prop work.

    The ski was running 84.3 before the Riva SC upgrade, Waterbox, and Riva adjustable nozzel, I will try the 15/22, but I think I will need more prop!!

    The only way to know is to measure AFR and RPMs..A custom tweaked 15/22 will most likely yield better results than just slapping the prop in the pump and riding. Speedfreeks does good prop work.
