Mercury / MerCruiser OEM Gasket — Part Number 27-804076003
Brand: Mercury / MerCruiser | Condition: New Old Stock (NOS)

You are purchasing a genuine Mercury/MerCruiser OEM Gasket, part number 27-804076003. The "27-" prefix in Mercury's part numbering system designates gaskets, seals, and O-rings — critical sealing components used throughout outboard and sterndrive engines to prevent fluid, fuel, and exhaust leakage at mating surfaces, ensuring proper engine performance, cooling system integrity, and long-term reliability. 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: Gaskets are engine-specific. Always verify your engine's model number and serial number before ordering to confirm this gasket fits your specific application.
