SIERRA MerCruiser 3.7L Exhaust Elbow Gasket – 18-0881-1

Replacement exhaust elbow-to-manifold gasket for MerCruiser 3.7L four-cylinder engines equipped with the aluminum exhaust manifold used in the mid-to-late 1980s. It seals the exhaust and cooling-water joint between the manifold and elbow and is intended for service where the elbow is removed or replaced.

• Exhaust elbow/manifold sealing gasket
• Designed for the aluminum-manifold 3.7L installation
• Replace whenever the elbow joint is disturbed
• Helps isolate exhaust gas and cooling-water passages
• Verify engine serial number and manifold style before installation

For marine engine and drive parts, fitment can vary by serial number, gear ratio, casting, or prior service history. Compare the original part number and physical configuration before installation; replace related gaskets, seals, races or hardware when their condition requires it.
