Evinrude Water Problem

[michaelwelborn]

Have a 1973 Evinrude 65 Hp and I am getting water in the number 3 cylinder. Had this problem 2 years ago. I replaced the Head Gasket last spring and it ran great all last summer. Have had it out 5 or 6 times this year and it ran great also. Last time out on the water it would take forever to get up to max rpm at WOT. Once it did it ran ok but had a small rattle in the engine and was not performing as good as usual. When I got home i pulled the plugs and the number 3 was wet. I did a compression check and Have #1-110psi #2-105psi #3-90psi. I Pulled the head and the gasket does not look damaged. The #3 piston has a very small hole in the center but it does not go all the way through. It is a perfect hole almost like it was done with a tiny drill bit. Have you ever seen this. Head is straight and I will put on a new gasket. What else should I check for this water problem? Thanks for the advice!
