I purchased a 1988 Johnson 90hp VRO this spring. Installed it on my 1960 17'6" EM white. The first time I used it I found it was lacking power. Not a lot but 70hp could walk away from me. Changed plugs when installed. After a few trips I decided to see what the spark plugs looked like. Pulled all the plugs and noticed #4 cylinder looked milky but still had coloring like it was firing. So I pulled head and replaced gaskets. Still getting water droplets in cylinder. Cylinder compression test was 125 in all cylinders befor and after. Any suggestions?
