I had water in both cylinders after a day on the water, which suffocated the engine.(1965 Johnson 9 1/2) It was a decent amount of water, not just some drips. I drained the water, cleaned the cylinder, and installed a new head gasket ...same problem again though. There was water in both cylinders. I didn't have a torque wrench, so it's possible I didn't tighten the bolts enough, but I doubt it. Another weird possibility,..some wasps made nests in my cylinder head bolt holes, which meant there was a little bit of dirt in the holes when i reinstalled the bolts, but I also doubt that. Besides the possiblities of those things, what else could be the problem, i.e. cracked head etc. and what are the options for fixing.
