    Noise in the motor??

    Hey guys...I was out on my ski yesterday and i was running about 50mph on pretty flat water and all of the sudden i noticed a sound. It sounded like a constant currrr sound if that explains it. When i put the throttle to the bar it also sound like a louder whisle sound aswell. And at idle i can for sure notice a louder motor. Does anyone know what this might be?

    Check the hose from the s charger. Also check all the hoses from the exhaust. One may have popped off. Are you down on power? Do you have metal washer in the charger? If not you need to pull the charger and have it inspected and replace the washers. Inspecting the charger is a good idea either way.

    I think the jet pump can make a whistle if the bearings are going... I could be wrong though, just what I heard.
