    Vibration in Drive shaft

    I was starting to winterize today, and was flushing the ski. While it was flushing it started to make a very loud vibration sound. After messing around I figured it was coming from the pump area. I pulled the pump off so just the shaft was exposed. After some troubleshooting this is what I found. If you start the ski with the pump removed the noise is gone, but if you move the driveshaft a little it will start again (while running). I'm new to Seadoo, not to skis. If you look down the shaft you can see where it enters the hull, when you move the driveshaft while it is running something will start vibrating and won't stop. If you shut it off and wiggle the drive shaft, then start it up again it will stop. But it will eventually start doing it again. It is an 07 GTI. Still under warranty, but I don't like taking it to the dealer. It has never done this before. The vibration is ridiculous loud, engine runs fine, normal idle etc...

    When looking at the parts break down for an 06 it seems to be part 36-38 I'm guessing. Or the noise is coming from that area. Link to parts diagram:

    Defintely in the drive shaft. Any ideas what it is?

    Question, how do you start the engine up with the pump removed? Did you take out the drive shaft as well? (I hope) If you didn't I would think the drive shaft would flail around in the pump show area.

    All late model seadoos sound horrible on the trailer, and sound like the pump is going to blow up at any moment. There is a resonance when the pump is not loaded.

    No, the noise is definitely different. It hadn't ever done it before. I guess I will just take it to the dealer since it is under warranty still.

    So I put the pump back on to take it up to the dealer and the noise is gone. Very weird.

    So it did the noise again while flushing the ski. Took it to the dealer, told me the carbon seal heats up and sticks to the driveshaft and causes the vibration. I though it was something along those lines. Nothing was actually wrong.

    if you start it out of the water spray some water on the carbon seal to lubricate it and you won't have a problem.

    That is one of the more rediculous things I have ever heard a dealer say.
