    Angry 2011 RXT 260 IS RPM fluctuation?

    I took my ski out yesterday for a few hours and all of the sudden the ski would only max out at 40mph when I went from idling in a no wake zone. When it maxes out at 40mph, the RPM's are going up and down by a few hundred non-stop. Whats wrong? First thing I checked was to see if the supercharger whine was still present and it was as loud as it has been since day one with the engine cover off. This is my first ski and this one has given me nothing but trouble over the past year and a half. Seriously considering selling it before more problems arise. The ski is at 71 hours. My boats are so much more reliable. What the hell is wrong now?

    What's your max rpms?

    Have you rebuilt the charger yet?

    Any recent work done to the ski?

    I didn't check the RPM's because I was in a hurry to get it out of the water because the heavens were about to open up on me with lightning all over. I can't imagine the S/C needs to be rebuilt at 71 hours. I don't abuse the ski. Wouldn't it be covered under warranty if the washers need to be replaced 30 hours before they say the S/C needs to be rebuilt?

    First thing I would do is change the spark plugs and make sure you have fresh fuel.

    +1 on changing the spark plugs and fresh fuel.

    No the charger rebuild isn't a warranty item.

    Also run some fuel Injector cleaner thru it.

    It really could be something as simple as the spark plugs? This is my first ski and these things seem like they have way too many issues.

    March 2012 after the dealer flushed the ski due to a broken carbon seal and the engine compartment flooding.

    Plugs should be changed Atleast 1 time each year.
    Usually at the beginning of the season.
