Well, not two days after I put my water ingested boat back in the water, my son's best friend and riding partner has joined the club. This 99 GTX limited ran missing a drain plug and took on a bunch of water.
Helped pump the water out, lubricated it, got it running again and back on the water within an hour. It idles fine, responds to light throttle but dies once any deman for power is requested. I had him run it while on a trailer backed in the water for a good 20 minutes just off idle to try to dry it out good, but nothing past a third throttle. Maybe 3k rpms.
took the boat back out of the water and the 951 wants to run away. This has air leak written all over it. Checked compression and it was low, like 90 on both cylinders, but it didn't seem to bleed off. I don't want to assume, but is it possible that the water that was ingested blew a base gasket or crank seal?
Out of all the ingested engines I have serviced, I cant recall that happening. When my 951 sank, it ended running normal after getting the water out, this ski ran great prior to this, but I can't help but think big time air leak now. With seat off and in the water while still on the trailer, there wasn't a drop of water leaking anywhere. I cleaned the RAVE valves and they were full of water/sludge.
I suppose I just found it odd that both cylinders measured at 90 psi. It seemed to me that a cylinder leak would leave one different than the other.
Before we yank his engine, I was just wondering if anyone thinks it could be anything else. Out of the water, it starts right up, idles normal for a few seconds and then starts screaming at around 4-5k rpms.
Thoughts? Pressure from water possible created leak? It sure seems like it.
Pulled head, very minor scoring on both pistons, nothing even close to the scoring one of mine has and mine runs fine. Should also note that while out of the water, when hose was turned on, it had an effect on the idle as it varied. Gotta be an air leak right?
99 GTX Limited 951, ran perfect until this incident this morning.
