My 1997 Force 75hp 3 cylinder has a dead cylinder because of water getting in the cylinder. Compression check showed 135 top, 130 center, and 135 bottom. I replaced the head gasket anyway. Checked the cylinder and didn't see any cracks. The old gasket was nasty but seamed to have a seal all the way around. Started it up, same problem. Runs good for about a minute and then loses the top cylinder. The spark plug has water on it again. Now I'm thinking it's the exhaust plate that is leaking water into the exhaust port. Easy enough to check except all of the bolts (about 18 of them are corroded into the block. 3 of them came out easy and the rest not. I broke off two heads while using penetrating oil, shock, and heat. Now I'm thinking of breaking every head off and drilling them all out. I own a machine shop so I have the capability to do it, not that I want to. Am I on the right track or am I making the problem worse? Also, I can't think of any other reason why there would be water in the number one cylinder. Any suggestions would be greatly appreciated.
