    2009 260x exhaust issue

    I had my 260x in for the first time today this season. I did some maintenance over the winter. Jet pump upgrade, supercharger fluid, intercooler clean out, new exhaust hose. (Original hose got hard and started leaking).
    Ski ran good for about 10 mins and then started to loose power .... Tons of white smoke out the rear.
    Got the ski back to the doc and popped the seats. Salt water all over everything. Also about 2 inches of water in the bottom of the ski.

    Hooked up the hose and started the ski .... Water started shooting out from the back of the ski by the inter cooler. Reached back by the exhaust and felt a 1/2 hole in the brand new exhaust hose.

    I am not sure if the hose was defective or there is another issue which would cause that hose to blow within 10 mins of riding? I did get any codes the entire time. Checked the oil and it look perfect. Any help would be appreciated.

    A picture of the hose would help determine how it failed.

    I won't have it torn down until the weekend. The hole is closer to the waterbox. It's big enough to fit your index finger in. I did not think there was any pressure in that line. Is there a flap similar to what boats have that stop water from entering the exhaust that might be locked up.

    In the down pipe on the exh there are 4 small holes that allow water to enter the water box and cool it, if they block up u will burn up the black plastic piping.... just a thing to check......happens after long storage and is caused by poor flushing and the corrosion bl8cks them at next 1st ride.

    I just had the exhaust apart and installed new gaskets. I will double check it when I tear it back down. Thanks for the info

    What does that value on the front of the water box do ? I did notice that when I had it apart. Could that cause the hose to blow if not functioning properly?

    The valve allows water to drain from the cylinder block. They block when you use your ski as a dredge.
