    06 Seadoo GTX S/C won't reach top speed

    I can't get my ski to reach top speed. 56 mph when the top speed should be 61??? It isn't displaying any other issues and seems to be running well. Starts fine and shots right up onto plain. It only has 42 hrs. on it and was garage keep for the last 5 years. When I pulled it out, I had to replace the starter solenoid, fuel pump and reverse cable. I had a maintenance done, but am not sure what was covered.
    I was at the ramp today and a gentleman told me that my supercharger may not be working. Could that be the case? Again, it seems to be running fine. I've heard horror stories of S/C blowing and the cost associated with it. I also keep seeing posts that ceramic and/or metal washers are failing and should be replaced. Please help.

    06 Seadoo GTX 4-Tec S/C

    If your charger has never been rebuilt then pull it and send it to jerry on this site for a full rebuild. The ceramic washers were used on 04-08 skis and when they break they fall into the motor causing a world of hurt to your ski and your wallet.
    Don't run it again until you get a full rebuild on the s/c. Bearings and washers.
    If the ceramics do get in your motor its 2k+ in repairs.
