    Question 07 f12x rev problem

    A problem started with my stock 07 f12x it has 52 hours on it, when I apply full throttle from idle or slow speed the revs go up and down between 6000 and 6600 and continue unless I back off the throttle, and then it takes off and runs great other wise, opens up and hits 62 mph at 6000 rpm, starts, idles and runs good with no other problems. Any ideas?

    It's cavitating....

    Either the prop is worm or the pump stator housing is worn or both. Best to measure them. Or better yet, after measuring the housing replace the prop with a 17/29 Solas prop.
