    Keep the repitch 14/19 or go with a 15/20

    I repitched my solas 14/19 myself and I am running 72.7-72.9 on GPS @ 8350-8400 RPM on the Stock Class ECU. How whould my ski spin the 15/20????? I have the air intake, Power pipe, stock SC ect the basic stuff and no IC.

    which way did you repitch the 14/19?

    if you added more pitch to it (ie bending the trailing edge down) then move up to the 15/20 and see how that goes. alot of people have had great luck with the 15/20 being a faster prop. What ECU do you have? this prop seems to be hit and miss with RR ECUs, but works well with the new flash 2006 ECUs

    His 14/19 was depitched on the trailing edge to enable it to turn up to 8400.

    Wilmer, no you will lose performance by going to the 15/20 without an external intercooler.

    Yes, an intercooler is your next step. I will tell you first hand that the Riva intercooler outperforms the Rotax Racing intercooler. The "other guy" won't tell you that.

    I sell both and make a better commission of the rotax item but will still tell you the Riva is better.

    Hows that for an unbiased opinion?

    Nobody has tested the new Rotax SC impeller as they have not arrived yet.

    Its up to you Austin. You seem to be getting some good results with your RR IC. I hope you can come to Mudbug so you can Ride Carey's ski and note the difference.

    Cudos to what Jerry say, i gain 50 rpms and more throttle response with my stage II RXT when i ditched my R/R ext. int and put the Riva power cooler, this is very simple, if you want be in front of the pack you need the Riva power cooler.
