Sierra Marine Head Gasket for Johnson/Evinrude Outboard Gaskets & Seals

Sierra Marine head gaskets are replacement cylinder head gaskets for Johnson/Evinrude outboard engines. The head gasket seals the joint between the cylinder head and the engine block. It keeps combustion pressure in the cylinder and stops coolant and oil from leaking across that joint.

Key Features:

• Aftermarket replacement head gaskets for Johnson/Evinrude outboard motors
• Seals the cylinder head to the block to maintain compression
• Helps prevent water jacket and oil leaks at the head joint
• Built for marine use, including heat cycling and exposure to moisture
• Sierra is a long-established supplier of marine engine parts
• Available in multiple part numbers to match different engine models

Use a new head gasket whenever you remove the cylinder head for overheating repairs, a powerhead rebuild or routine service. Select the child item that matches your engine's application.
