This heavy‑duty aftermarket cylinder head gasket is a dependable interchangeable spare for Tohatsu, Nissan and Mercury 4HP & 5HP M4B, M5B outboard motors. It replaces OEM part numbers 369‑01005‑0 and 369‑01005‑1.
Manufactured from multi‑layer composite high‑temperature‑resistant sealing material. It features outstanding pressure‑resistance, thermal‑resistance and anti‑corrosion properties. The gasket stands up to high combustion pressure, frequent temperature fluctuation and salt‑mist humid marine conditions to maintain consistent sealing performance.
Positioned between cylinder head and engine block, this gasket seals combustion chambers and cooling passages.
Proper sealing prevents compression loss, cooling‑water leakage, gas blow‑by and mixing of cooling water with combustion gas, securing stable cylinder compression for reliable engine operation
