Just bought me a 96 speedster! Lots of fun! I Love the thing! Everything runs well, however, I am getting cavitation when jumping out of the hole. Not too bad with two in the boat, but I'm worried about having more than that or when I pull a skier. I'm not sure if it is the wear ring because it does leak just a little bit, which leads me to think it is the carbon ring. But I don't really know. I had a 95 XP, but the through the hull area was completely different. If it is the pressure between the carbon ring and stainless ring, how do I tighten them up? Please help, I got to get on the water!

By the way, this forum has been very helpful. Please keep writing in with questions, I'm learning a lot.

Thanks much,

Welcome to the group man!
I imagine your '95 XP probably had the bearing carrier seal, like the '95 boats. It had seals and a bearing instead of the carbon/ss setup. If you want to put a little more pressure on the ss ring, loosen the rear clamp on the bellows hose, and slide it forward a little. You might want to visually check the sealing surfaces first, and make sure the carbon is flat and not pitted or 'wallowed' out. the ss ring should look flat too. If they are OK, then slide the bellows just a little forward, and tighten the clamp back up. Take it out and test it, man! You can leave the gray plastic guards off long enough to see whats going on.
Get a flashlight and shine it in the pumps, from the rear and from underneath. You may be able to see the wear ring well enough to see it is has any 'chunks' or well worn areas. It will look scuffed, thats normal. Make sure there are no ski rope 'remnants' or fishing line or anything behind or before the impellers. Post back and let us know how yer carbon rings look. Happy DOO'ing!

tiggerman, you are the sea doo guru, thanks a lot.

You are right about the 95 XP. It may be more maintenance but I know how they work.

I just looked at the impellars and wear rings and they look brand new. It must be the carbon rings. I will attempt to "adjust" them tomorrow. thanks again.

No problem, man! Remember, if you can't get the carbon rings to seal to your satisfaction, you CAN retrofit to the '95 setup. Good luck!

Trying to slide that hose forward is a lot easier said than done. I did get it though. It helped some, but it still cavitates. Is the boat supposed to be able to get on plane with just one engine. Mine won't. I cavitates too much. Is there anything else that could make it cavitate other than the carbon ring and wear rings? I can't figure it out. Thanks a lot.

Any 'air' leak in the driveline. I think on your '96, there was a neoprene gasket that sealed the pump to the pump shoe. If that's messed up, it can 'suck air'. Sometimes, the pump shoe or the rideplate aren't sealed properly to the hull and can leak as well. I just took my starboard rideplate and pump shoe off to look, and I should have left it alone! I almost never got them off!! They are held on by screws and bolts, but they are also sealed with heavy body silicone sealer. I guarantee mine weren't leaking. I would leave those alone. Could you pull the carbon rings back and see the sealing surface?
Some guys say their twins can plane on one engine, but that's after they did the carrier retro. We'll see!
