2006 Yamaha 1100 filling w/ water @ WOT

[scott07]

The ski works great and runs gret except at WOT and only WOT the hole ski fills w/ water in an instant. I have checked all hoses, clamps, drive shaft seal, and checked the hull for cracks. Everything seemed ok. I tried watching the inside w/ the seat off to watch for where the water was comming from but i couldn't tell. If anyone has an idea forme let me no.

take an insurance policy out on the ski, let it sink, and buy a superjet.

no really you sure all of the cooling line clamps are secure and most importantly is the flush valve closed?

Try Putting the ski on a trailer and fill it with water.
Just enough to check for leaks/dont fill it up
A few inches in the bottom is enough.

06 1100 ????

What model is that ?

If it's a GPR than I would take a close look at the pump shoe area and pump intake.
There have been issues with the pump shoe inserts pulling out (mainly 03's) and the pump tunnel cracking.
