1980 Evinrude 70HP, 3 cylinder. Evidence of fine water droplets in the center cylinder. Compression of all three cylinders is 125 psi, each within 2 or 3 psi of each other. The spark plugs on top and bottom cylinder have just a light film of clean oil or gas and oil. The middle cylinder plug has a white cloudy film on it, which I am assuming is a mist of water. That cylinder fires but not consistently. First reaction was head gasket or cracked cyl. head. But if so how could compression be equal. Where else could water come from? Where do I go from here?
