Ringing noise normal? Bearings bad?

[jhicks]

Hey guys,

I am new here. I bought a 1995 Seadoo Gtx 2 years ago. Within 1 hr of running the rotary valve went bad. 2 dealerships/marinas ripped us off and cost us a lot of money for doing nothing. So I ended up changing the rotary valve myself. after done putting it all back together it would really struggle to turn over. Then it turned out that the drive shaft was binding. So that got put on wait, and now we got that fixed. Its now running with no problem. We were running it and had to adjust the idle speen no problem. Then after we did that hit the gas (all with water running in it) and we heard a ringing sound coming from the back by the impeller. I thought it was normal. The friend of mine couldnt remember if his used to ring like that.

He suggested to anyways take out the back bearing to check for shavings, and oil in the system sense that needs done anyways.

1.) how do i take the whole back end out of the ski to get to the bearings? pics please.

2.) is the ringing sound normal? Should I worry?

3.) are my all 3 bearings bad? or all ok?

4.) any suggestions?

Thanks guys!
Jamie

Jamie, the rattling noise is for the most part normal. It is possible that in a 95 seadoo that the pump oil might need changing. If you look into the nozzle in the rear of the ski you will see a cone with 3 screws and an oil filler allen screw.

To change it,
1) Take off 4 13 MM bolts holding nozzle and 10 MM bolt holding steering.

2) Get something to catch the old oil in, drain pan or margarine cup etc.... (don’t forget the nose plugs, the oil stinks to high heaven)

3) Remove the 3 8 mm bolts holding the cone on.

4) Pull the cone and drain the oil out. Prop the front of the trailer up as high as you can to get most of it out.

5) Inspect the rubber “o” ring and if it is good apply silicon and reinstall the cone. Make sure the allen fill plug is on top.

6) Lower the front of the ski and add oil** to the cone. When it is full, take a brake and have a drink. There is air in the cone and when you go back you will see that it is low. Top it off and take another brake... do this until the fluid does not lower again. I often start the ski for a few seconds to make sure oil is all the way worked into the bearings and all the air is out.

7) Wipe silicon on the set screw and screw it in (be sure not to run it all the way into the cone. just deeper than flush is fine. Let it sit 24 hours to cure the silicon and put the nozzle back on.

**NOTE: Use Sea Doo 75w90 GL5 Synthetic Polyolester Oil
I hope this helps out.
