    2004 RXP Top Speed loss

    So over the past two weeks I've been killing my brain trying to figure out what's been causing my RPMS to drop. I had changed the oil, wear ring, plugs 3 times, checked SC slip, OPAL block offs, Piggy back harness, everything even close to having an effect on speed or RPMs. My ordeal is im dealing with is I'm stuck at 7500 rpms. The ski idles perfect. Has good holeshot. Runs 63 on GPS with a Stage 1.5 kit other than intercooler. I had seen it at 73.8 before I bought it. Well when I bought it the P.O. who is the original owner had the full SC service at 100 hours. Well he just now calls me and says I just remembered. I had my solas prop replaced with another. He said they didn't have to order one when he had it done so that makes me believe they threw whatever pitch prop on it they had lying around. I know before this it had a 14/19. What pitch prop could they have installed to drop the RPMS from 8100 to 7500-7550??

    Sounds prop related. Pull pump and check. Might just need to be pitched to 8100.

    I'm gonna have to just order a 14/19 prop. I don't have impeller tools and I refuse to pull the pump 4-5 times for a prop shop to fine tune a prop. I'll just go the route with ordering a new one that I know will be closer to what it should be running

    Prop tool is a great investment. And pitching your own prop is quite simple.
