    Congrats on the new ski. Your ski isn't going any faster until you reflash the ECU to remove the speed limiter. With the MaptunerX, you can reflash it with the bone stock tune which removes the...

    I charge $50 to change the washers, but if that supercharger still has ceramic washers in it then it’s going to need a full rebuild. It’s waaaaaay overdue as these things need to be rebuilt every 100...

    well, you didn’t exactly dodge a bullet. The ceramic clutch washers have failed and with that much run time your oil pumps will be shot. You will need to pull the engine and replace the front and...

    If you do ever upgrade to a stage 2 tune then you will want the Solas impeller, not the Skat Trak.

    Most likely a boost leak. Have him check the hose where it connects to the throttle body. It's the most common spot for a boost leak.

    This is not a common issue. I see it happen when people mount the motor too far rearward and don’t leave a gap in the coupler. This causes the crankshaft to thrust forward which wipes out the thrust...

    yes my mistake. The 120,000 rpm figure is what the 300 supercharger bearings are rated at.
    a 300 Engine spinning 8800 rpm has a supercharger spinning 51,500 RPM
    at 9000 RPM the supercharger is...

    this vibration people refer to is actually compressor surge. Balancing the wheel to the shaft doesn’t rectify this. Using a good BOV reduces the amount of compressor surge (flutter)

    if you look closely at the clutch end of the 300 supercharger you will see the supercharger has grind marks they use to balance it. You won’t see such marks on the 185/215/255/260 superchargers.

    These superchargers are called “maintenance free” by Seadoo so Sea Doo doesn’t offer rebuild parts for them. Fortunately our friends at Rotax Racing provides a kit and that kit is available right...

    Stock valvetrain is safe to 8700 RPM.
