Jet ski filled up with water.

Question

I am new to the jet ski world and have had this particular model for about a month, kawasaki 1100ZXI, and today we were on the lake and the ski filled up with water. Put it back on the trailer and drained water, replaced plug and put back into lake and here comes more water. Started ski while in water and couldn't find anything leaking from any hoses or anything. Drained water again did this 3 or 4 times couldn't find any leaks. Brought ski home filled up with water hose and watched for leaks and nothing, from the inside out. Anybody have any ideas what could be causing this? When you run the ski across the lake water is pumped out by bilge pumps, then when you stop and float is when it starts to fill up.

Answer 1

I had this problem with my Sea-Doo, check the mounting of the bilge lines. They are normaly mounted above the pump. If they came loose and fell into the bilge itself, the water will siphon back into the ski when stopped. Hope this helps.
