    Possible carbon seal leak. Does the 08 GTI have a siphon /bilge pump?

    My 08 GTI has developed a bit of a leak.

    I put it in the water recently and let it sit for 30 minutes....no leaks.

    I then ran it for 15 minutes and stopped to check. There was water, but not enough to end the ride.

    About 3 hours later (1 hour riding, 2 sitting), there was approx. 3 inches.

    When I got home, I filled it about 1\5 with water and there were no leaks.

    I suspect the carbon seal is leaking.


    #1. Is this a DIY project?

    #2. Does the 08 GTI have a siphon / bilge pump? Is it safe to ride with the leak until it's fixed? (85 this weekend)

    Yes, the GTI has a stock siphon. In fact, take a look there first and make sure the clear hoses are still connected to the yellow elbows near the pump tunnel.

    I just did the carbon seal on my 08 GTI. It's a DIY project if you're familiar with these skis. Look around there are a few threads on this topic.

    Don't ride if you have a leak....

    Did you cover the carbon seal with water to see if it is leaking out??

    Is the water you find in the hull hot or just regular temp???

    Also make sure your siphon tubes are in place in the steering nozzle as well!! If they are missing, it will fill the ski and not bail the ski!!!

    Hi,

    I did not test the temp of the water, so not sure about that. I'll get it in the river this weekend to check. When I partially filled it with water in the driveway to check for leaks, I made sure there was enough water in the hull to cover the seal. No leaks were detected sitting in the driveway.

    I had never noticed siphon tubes before, but after a closer inspection, I did find 2 in the rear.

    I had to remove the coolant tank to see them. They go from the bottom left and bottom right portion of the rear hull to the pump.

    Are there supposed to be others?

    So, I assume, if water settles in the back/bottom, while running, the pump should siphon out the water?

    I plan on backing it into the water this weekend, and while still on the trailer, start it up and see if the seal leaks.

    Yes, there are 2 little tubes that stick out into the steering nozzle. That is what makes the siphon bilge work.
