I replaced an obviously bad head gasket on this 89 50 HP, because it locked up due to water in the cylinder ...At first, motor ran great, with expected power and acceleration ... 5 minutes later, power decreased immensely. Pulled the plugs and top was fine, but lower cylinder had obvious water on it. I ran a compression test, and top cylinder is 119 with lower at 100 ... Is my head gasket install bad, or any ideas where I should turn to for a remedy? Thanks!
