    low power and grinding ratteling noise from sc area

    hey guys, my buddy has an 06 rxp with metal clutch washers, was out with him earlier and he said it started wistleing louder then normal but seemed to run fine (i did notice this too from my ski) then he gave it some gas and it started making a rattleing noise, i heard it too sounded like the pump area. towed him back in started ski on trailer and noticed the noise in the area of the s/c i can still hear the whistle from the blower. hes had a slight vibration for while now too and i noticed on take off it has some cavitation (i was on it earlier) rpms went up but felt like the ski was not accelerating quick enough (kinda like a slipping clutch on a car) its going to the dealer tommorow but he is out of warrenty and i have a feeling i may be working on it if its major$$$. ski has 144 hrs thanks guys in advance

    Pull the pump off the ski. Remove the nose cone where the grease goes. Is there water inside the cone mixed with the grease?

    If you find water in the grease, your pump will need to be rebuilt. Mine has 111 hours and I found water inside. I was noticing a grinding noise at 4500 rpm from the bottom of the ski. Pulled the pump with Jim (OU812) and found water in the grease and the bearing shot.

    The bearing spins at whatever speed the motor is turning. The water cools the pump bearing. The pump gets very hot at riding speeds.

    Let's hope you find water in the pump nose cone. A lot cheaper than a motor issue.

    sounds like you need a new wear ring.

    You may have sucked up a rock?? It will sit in front of your prop and rattle pretty good...

    My ski had similar symptoms a few weeks ago, started as a small vibration, rubbing sound that gradually got worse. I thought for sure it was the pump bearing going bad, turns out it was a supercharger bearing. 145 hrs on ski at the time, fixed under warranty.
