Product Description
The Sierra Marine Head Gasket is designed for Mercury/Mariner models 9.9C (S/N code 682) and 15C (S/N code 684). This gasket forms a crucial seal between the cylinder head and engine block, preventing combustion gases and coolant from leaking. A proper head gasket seal is vital for maintaining engine compression and preventing overheating in marine engines.
