    Limited to 5600 rpm! Worked Fine before winter.

    Ski normally has a ton of power, 8000rpm and around 69 on the dash. This is my first time on the water this year. I just charged the battery, cleaned the contacts, and the ski starts instantly.

    Now, it will rev to about 5500 and ignore any throttle pull past that. It'll climb to around 42mph. Can barely pull 2 wake boarders up. Also, the ski seems to sound different, like it has this lower pitched throaty type thing.

    I just changed the oil with seadoo xps. Oil is a tiny bit high (top mark). Fuel pressure is great while riding. I removed the supercharger input and output hoses whole changing the oil so I could grab a wrench I dropped. I attached them very tightly, and then again when I suspected there was some sort of leak.


    In the garage on hose, I did a few quick revs and saw 7400rpm on dash. Thanks for any advice

    -Did not change plugs, did not use fogging spray. Used last year's gas 2 days ago, and used new gas yesterday (no change). I do get a MAINT message on bootup - I assume its just going on a timer. No stable or additives in gas.

    I would change the spark plugs. Old gas can foul plugs easily.
    I also see that you have a 07 s/c model. Did you change out the ceramic washers?
    I've seen the washers break and limit the ski to around 40 mph and 6k rpm.

    Pull Supercharger hose off and see if you can spin your charger by hand.. also check the hose to see if there is grey dust in it. if you notice any of these problems. Well you have a bigger problem.... If not re install make sure there aren't any boost leaks. and Install new Plugs.

    Sounds like the SC is not working check what Adam said.

    What's an easy way to check for boost Leaks?
    It is an 07 but has the 08 supercharger rebuild kit installed (metal washers).

    I tried to turn the charger wheel by hand, and could for about half a turn, and then it becomes incredibly difficult to budge it.

    Is the different sound a clue?
