2002 GTX, 4 tech Limited, Water in spark plug hole

[Reast1]

Just repaired the head on this machine that had slight water damaged on the #3 cylinder. Unit was reassembled, compression was 160 psi on all 3 cylinders. Stared up and ran pretty good with no exhaust cooling water. Only ran for 30 sec two different times. Hook water up to the flush port in the rear and ran agin. This time tthe longer it run (2 mins) the worse it got. Stopped immeadiately and check compression agin. All was well. Started agin, harder to get started and things got worse. I was loosing power. Remove plugs agin to check compression and found lots of water coming out of the spark plug hole. How can this cooling water get to this point. What likely has failed?

Unit has been dried out and waiting on me to return. Unit was running better better but not on all 3 cylinders. Suspect foulded plug

Did you torque to specs? Staight-edge the decks? Re-use any gaskets? Bills

Bills86e,

Yes, did all that stuff to the best of my ability. I am new at this Rotax motors etc. I just now learned that you cannot turn water onto the ski before you fire it up and that is what I did. I dried out the top end pretty well and just called it quits for the day when all this took place. I may be better off than what I think. I will give it another go this weekend.
