Sea Doo Swamped. Need help fast!

[getinmerry]

Hi to all!

I'm new to this forum. I don't actually own a PWC, but I fix and maintain one for a friend of mine that is laid up.

Anyway, he brought me his Sea Doo GTX (unsure of the model or motor size at the moment). It had been almost submerged for up to two weeks.

I drained the water, pumped out the cylinders and managed to get it running last night. Both cylinders were full, but with some TLC it did fire up and seems to run okay.

I need to know what else to do for it to help make any further damage minimal, and to find out what is letting the water into the boat. The water level was about even with the top of the motor from what I was told.

There was no storm or other reason for it to be flooded. The water is getting in some other way.

I am very adept at fixing the Sea Doo because I'm a snowmobiler, but there are some things I'm not used to on PWC's. Please let me know what I need to do here.

Thanks,
Chuck

A friend of mine is having the same problem with his 96' GTX, he had been working on it quite a bit, and replaced a bunch of parts to solve this problem, in fact he lost a lot of "play time" this season. The last time out, it was still cavitating, and taking on water, so he thinks it is a worn carbon seal around the impeller, and is in the process of replacing it now.

After a considerable amount of searching, I have come to the same conclusion. It appears the carbon ring may be to blame. I'm going to drop the Sea Doo into my neighbor's pond tonight and see if I can find out for sure.

I just spoke with the owner of it, and he told me that the speedo stopped working last time they used it (just before it swamped). Anyone know if this could be related in anyway?

Thanks,
Chuck

Re: Sea Doo Swamped. Need help fast!

The only way he is getting water in that ski is
Forgot the plug
Has a ceack in the hull
Has a leak at the driveshaft through hull fitting ( carbon seal) which is most likely the problem
Or has a leak in his water lines.
if its a 951 they are known for a leaking problem right where the exhaust manifold bolts to the pipe.

Here's the current poop:

I spent the evening working on the ski. I put it on a hill and flooded the inside again enough to cover the transom plate and submerge the drive shafy and carbon seal.

The results were suprising. I found a total of 5 leaks. Each of the two "bumpers" in the rear sides leak, two of 4 bolts on the impeller grate leaked, one of the drain plug flanges leaked, and no suprise here, but the carbon leaked...pretty bad.

I followed the preload instructions in the service manual to measure the boot preload and it was fine. The slide plate on the shaft was frozen...thus no sliding was occurring and it had elongated the carbon seal.

Now my question, how bad is it to pull the shaft and replace the carbon and boot? Are there other parts to replace while I'm at it?

Thanks in advance?
Chuck

That Much Water Can Only Be Casued Buy A Bad Driveshaft Seal. Put The Ski In The Water And Start It. Look Behind The Engine Where The Driveshaft Goes Threw The Hull And Out To The Pump, If You See Water Coming In. That Is Your Problem

I changed out the carbon ring, bushing, and end seal bearrings on my 1995 xp last year. Getting it out was not a problem, but putting it in took a little work......then again I did it by myself, but if you have someone to help you hold the boot in place, it should not be that big of a deal.
