315538 OMC GASKET

The OMC Johnson/Evinrude 315538 is a water jacket gasket (also called head cover gasket) for 2-cylinder Johnson and Evinrude outboards, compatible with 35 HP (1986-87), 40 HP (1984-88), 45 HP (1987-92), 48 HP (1987-88), 50 HP (1971-75, 1979-88), 55 HP (1976-81, 1983-92), and 60 HP (1980-85) models. Equivalent to Sierra 18-0941, this gasket prevents coolant leakage and maintains proper engine temperature. It is essential for preventing water intrusion into critical engine passages. Replacement at service intervals maintains engine cooling system integrity and prevents overheating.
