I've fully restored a 1967 3hp Evinrude Lightwin o.b. motor. When test running the motor, it would not run properly, after inspecting the spark plugs I discovered water in the cylinders. I found no obvious reasons why.
Need help!

Darn nothing is ever easy. Your compression numbers seem fine to me, in fact quite good. Next step I would do is replace the exhaust cover gasket or at least tighten your exhaust cover screws. When it was running were you seeing white smoke/vapor? Rick.

Hope you didn't run it long without water. Not a good idea at all but it helps prove water intrusion for sure. What about those exhaust cover ideas? Rick.

Thanks Rick, ran it only for a second or two for confirmation that water was the issue.
As for the exaust cover, the gasket is new installed with gasket sealer, pretty sure it had a good seal. If not how would that cause the problem at hand, eh.
thanks for the help! I'm new to this forum please excuse my mistakes while I learn the ropes.
Look forward to using this site more often!

No? I positioned the gasket so the head bolts fit through. But could it be backwards or upside down? I'm not sure!
How do I tell? Could this cause the problem? sorry for the delay,
