Sierra Marine Head Gasket for GM Engines

Sierra Marine Head Gaskets for GM engines are replacement cylinder head gaskets for marine inboard and sterndrive engines. Sierra designs them to seal the cylinder head to the engine block, so they hold combustion pressure and keep coolant and oil in their passages. Use them for engine rebuilds, overhauls, and repairs.

Key Features:

• Made for marine use, including the heat, moisture, and corrosive conditions of boating
• Seals combustion gases, coolant, and oil between the head and block
• Aftermarket replacement for GM-based marine engines
• Backed by Sierra's reputation as a leading marine engine parts brand

Sierra is known for marine replacement parts that meet or exceed OEM expectations. A new head gasket helps restore compression and reliable sealing during a rebuild or repair. Choose the child item that matches your engine application.
