    Pump Noise !!!

    Well i started up my RXP today to change the oil and all that good stuff. I noticed that the usual pump noises have gotten louder. I know that it is normal to have some noise. What is the cause of the noise? And what can i do to limit this?

    Advise Appreciated!!!

    Hello Brad,

    The noise you are hearing when the ski is running out of the water is probably just the impeller rattling on the splines of the drive shaft.

    If it really bothers you, you can take out the pump and grease up the splines of the drive shaft and also coat the internal splines of the impeller. It will definately quiet it down but eventually the noise will return. The water gets in there at high speed and washes away the grease to leave metal on metal contact, thus the noise you hear...

    What kind of water do you ride in? If still hear noise i would check pump bearing as water gets in destroys bearing. when the pump is off try to shake the impeller in the pump if it does check the pump grease in the cone.
