    Unhappy 07 RXT won't go above 5600 rpms....need help

    Ski won't rev above 5600 rpms or so.

    Took the ski out last year and it ran great.

    Took it out for the first time this year and it won't pull above 5600 rpms or so.

    Flushed the oil about 8 times because it looked milky like it had water in it. Checked the spark plugs, no excessive fouling. Treated a fresh tank of fuel.

    It doesn't lurch or ramp up and down, which makes me believe it's not fuel.

    If it were the supercharger bearings or washers, wouldn't they foul up the motor?

    It seems like the the motor isn't getting any help from the blower. If the blower went bad, why would it be between outings?

    Could it be a fuel injector?

    Need help from the gurus.

    Thanks

    Pull off the intake on the front of your SC and see if the impeller spins by hand bro. report your findings back.

    My bet is on your washers have failed.
    Have you changed the ceramics to the metals?
    How many hours on the ski?

    Dont run the ski anymore until you do this. This just happened to me and I got extremely lucky and ended up with only some minor damage to my SC.
