    Default clanking noise!!!!!

    Ok guys im new to the whole pwc thing. i just recieved a 95 slt 750. The engine had been freshly rebuilt this past spring. But i have not used it since i recieved it. My problem is that when i got to turn the motor over theres a claning sound comming from the jet drive. teh previouls owner told me that it was because of salt build up in the housing. But iv also been told that the bearings need to be preplaced an if not ill end up blowing my enigne. AN i have no idea were i can get a bearing rebuuild kit. PLEASE HELP!!!!!

    My best opinion would be to purchase a Clymer manual and go to www.partsland.com for the illustrated parts breakdown. I don't believe there is a kit available. Purchase seperate parts.They are a reliable company and shipping is fast.

    The Clymer manual has pics. Be sure to buy the special tool from them if your model requires it.

    And use Ultra Blue Permatex RTV sealer to seal the pump to the ski.(avail at Wal Mart)

    You will also need new seals between the pump and the ski and new rubber bumpers for the drive shaft and also 2 new seals (P/N 3610040) for the center bearing support($12.00). or purchase the entire unit($95.00).
    Hope this helps.

    Cheers !!

    It might be normal these thing's sound like a box of rocks out of the water with no load. But you should check the bearings in the pump housing. Remove Item # 26 to remove the pump from the hull.Then check for bearing drag or tightness.

    Is the clanking noise while running on a trailer or in the water?

    I had a customer come in with a suspected failed jet pump on his Seadoo GTX 4tec S/C. I put the impeller housing on our stand and removed the cone and then used an electric drill to turn it over no noise other than from the drill. The bearings still had grease in them. We replaced the pump and it still had a “tinny ringing sound”. I have heard that this is because they are not submerged in water to act as a cushion. We checked the impeller clearances and it was within spec.

    usually just a tiny high spot on an impeller blade tapping the wear ring makes a ringing sound.
