Mercury Quicksilver NEW OEM Cylinder Head Gasket 879675 NOS Genuine Factory 0810

Mercury / Quicksilver OEM Cylinder Head Gasket — Part Number 879675

Brand: Mercury / Quicksilver | Condition: New Old Stock (NOS)

You are purchasing a genuine Mercury/Quicksilver OEM Cylinder Head Gasket, part number 879675. The cylinder head gasket seals the mating surface between the cylinder head and the engine block on Mercury and Mariner outboard engines — maintaining compression within the cylinders, preventing combustion gases from escaping, and keeping coolant and oil from mixing or leaking externally. A blown or compromised head gasket causes loss of compression, overheating, water in the oil, or white exhaust smoke, and requires immediate replacement to prevent serious engine damage. This is an authentic factory original part — never installed, never used.

Condition Details: This is a New Old Stock (NOS) part. The gasket itself is in new, uninstalled condition. As is common with NOS inventory, the original packaging may show signs of age, including shelf wear, dust, or minor cosmetic blemishes on the bag or box. The part is new and fully functional.

⚠ Important: Cylinder head gaskets are engine-specific. Always verify your engine's model number, horsepower, and serial number before ordering to confirm this gasket fits your specific application.
