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.
<br />Chase out the head bolt holes with a tap so you can be certain about the torque on the head bolts.<br />Then, put in a new head gasket, and torque the head bolts to 96 to 120 inch/lbs (with a torque wrench), tightening from the middle ones outwards. Too loose and it will leak - too tight and it will leak. <br />After the first warm up run, retorque the head. It will leak otherwise.<br /><br />I can't say I've ever heard of a cracked 9.5. The only other way to get water into both cylinders would be to turn it upside down.<br /><br />Good luck!
