Abstract
A cylinder head gasket for use in a marine engine adapted to be cooled by the water in which the engine is running, the engine having a non-ferrous alloy cylinder head and a non-ferrous alloy engine block, both the block and cylinder head preferably being made of aluminum alloy. The gasket includes a metallic sheet forming a core, the core having upper and lower surfaces, layers of facing material securely disposed upon those upper and lower surfaces, and wherein the electrolytic solution potential of the metallic sheet is approximately equal to the respective electrolytic solution potentials of the engine block and the cylinder head.
