Sierra Marine Cylinder Cover Gasket Gaskets & Seals

Sierra Marine cylinder cover gaskets are replacement engine gaskets for marine applications, including outboard powerheads. They seal the cylinder cover (also called a cylinder block cover or cylinder head cover) to help keep coolant, exhaust and combustion pressure where they belong. Use them when you rebuild a powerhead or reseal a cover that has been removed.

Key Features:

• OEM-level quality: Sierra states that each of its products meets or exceeds the original equipment part it replaces.
• Interchangeable: Many part numbers in the line are listed as interchangeable with GLM and Mercury Marine part numbers, which makes cross-referencing easier.
• Marine-specific design: The gaskets are made for marine engines, so they suit the conditions of boat use.
• Wide coverage: The line includes cylinder cover, block cover and related gaskets for many engine families.

Sierra is a long-established name in marine replacement parts. Its cylinder cover gaskets give boat owners and marine technicians a dependable way to restore the seal on a serviced engine. Check the individual part number for the exact engine application and OEM cross-references.
