HEAD GASKET Mercury (18-3864)

Head gaskets seal the cylinder head (where your spark plugs are) and the cylinder block to withstand engine compression and permit the passage of cooling water between them. It has earned the trust of engine manufacturers and boat builders, supplying them with OEM parts. Sierra parts are guaranteed to fit and restore OEM function. This superior maritime product met your budget and power requirements. It is the most strained gasket in the engine since it simultaneously seals oil, coolant, and compression from the cylinders. The head gasket seals the oilways of the cylinder head and block, allowing oil to circulate freely throughout the engine. The same is for canals, which enable coolants to migrate to the appropriate location.

Key Features:

• The head gasket maintains the pressure created by the ignition of the fuel vapor by the spark plug within the combustion chamber.
• Advanced manufacturing technologies ensure long-term performance.
• Ensure a more robust combustion seal.
• High-Performance marine head gasket.
• Meet or exceed manufacturer specifications.
