Powerhead Base Gasket — Mercury Mariner 40/50/60 HP EFI 4-Stroke
Direct replacement powerhead base gasket for Mercury and Mariner 40, 50, and 60 HP electronic fuel injected 4-stroke outboard motors. Fits both 3-cylinder 40 HP and 4-cylinder 50/60 HP engine configurations. The base gasket seals the joint between the cylinder block and the crankcase housing, which is critical for maintaining proper compression and preventing oil and coolant leaks at the powerhead mating surface. Engineered from durable gasket material rated for sustained marine engine temperatures. Mercury identifies outboard engines by serial number rather than model year — check your serial number tag on the swivel bracket to confirm fitment. Replaces Mercury 27-8M0213112, 27-8M0163129, and 27-892319001.PRODUCT NOTICE:
