    Fx ho question

    I have an 06 Yamaha fx ho and when I give it full throttle from a dead stop it tachs up to 10200 and hits the rev limiter. After a second or two once I am out of the water it settles back down to 10000 and no longer bounces on the rev limiter. When I am riding along and pin the throttle it hooks up and accelerates just fine without hitting the rev limiter. The more weight that I have on the ski the longer it bounces on the rev limiter before getting out of the water. Also, I only see about 51 mph top end irregardless of the amount of weight I have on the ski. Any ideas? I called R&D and asked if an intake grate would solve the problem and they said that it sounds like cavitation and the grate should fix the problem. But if the problem is cavitation then why am I only getting 51 mph top end when everyone else is stating they reach 58 mph give or take one or two? Any input would be greatly appreciated.

    it would be more likely from a worn prop
    that may be why your ski is also slower
    how are you checking the speed

    I am checking my speed via the speedometer which I understand is prone to inaccuracy, but most people say they see 56-58 on the stock speedo. Here's a picture of my prop. What do you think?Click image for larger version.
