    2011 RXT 260 IS lost 440 rpm's

    This has been happening for a while ever since the ski sunk over a year ago. That same day I took it to the dealer to have the whole ski flushed and all liquids changed. They said there was no damage done and everything was fine. It sunk from a carbon seal leak. I took it into the dealer again and they checked it out and said everything is great. They tested it and maxed out at 7600 and 66 mph. They ran it against another RXT 260 and they were running neck to neck. Not sure about the rpm's though. Why is it doing this? They checked the inter cooler and it was fine so that's out.

    The ski only has 55 hours on it so I would imagine the SC is fine. They said they checked everything out and it was all good. The plugs are a year and 3 months old. Would they really cause a loss of 440 rpm's?

    8040 top end.

    Your ski is telling you it is not right being down 440 rpm from 8040.
    I would check all hoses and clamps for boost leaks, SC slip is probably too low, it should be removed and closely inspected, and check IC to TB for water due to possible IC leaking. The comment from the dealer about running next to another ski is BS.
    You should be revving to 8100 and the ECU pulls back to 8040, and it should hold near that all day long. You should change plugs and oil prior to every season.
    Something is definitely off!

    I took it out today and it was at 66 mph. The dealer inspected the ski and said everything was great. I'm not a motorhead so there isn't much else I can do. Could the plugs be the reason? The inter cooler is perfectly fine. I meant to say 440 rpm's not 4040 rpm's.

    Take the ski out and run it down to the warning fuel light and pretty flat water trim in neutral position or a little above and see what your RPM's are. I have seen those skis struggle with a full tank of fuel to turn up 8000 rpm's especially when you are stock. If you are still under warranty take it back to the dealership if you do not get somewhere around 8000 rpm's with the low fuel. Don't care what they say there is an issue!!

    Where are you located? You need to find someone other than your current dealer to look at your ski. I agree with jpt7779, something is wrong.

    Thats a good idea. I pretty much run it on full most of the time because the gauge can be pretty inaccurate for me. Could a high oil level cause this too? What about running it on the highest trim setting? I mostly run on the highest trim setting for fuel efficiency.

    Too much oil can cause a loss of rpms..
    Warm up your ski with a 15+ min ride then check it after idling in for 30+ seconds. If its around 1/2 way between the marks your ok.
    If its higher then suck some oil out.
    I'd change spark plugs also and run some Lucas fuel Injector cleaner thru it.
    My 2011 rxt-x had similar rpm loss and I had a bad intercooler..
    If its under warranty bring it to a differnt dealership.
