The Sierra 18-0722 is a restricted dry joint exhaust manifold gasket designed specifically for General Motors marine V-6 and V-8 engines. This precision-engineered gasket provides a critical seal between the exhaust manifold and riser on engines utilizing dry joint exhaust systems.

Key Features:

• Square port design for proper exhaust flow alignment
• Restricted configuration for dry joint manifold applications
• Direct OEM replacement for MerCruiser stern drive engines
• Heat-resistant construction for demanding marine exhaust environments
• Single gasket per package

Engine Compatibility:

• GM 4.3L V-6 engines (2002 and newer)
• GM 5.0L V-8 engines (2002 and newer)
• GM 5.7L V-8 engines (2002 and newer)
• GM 6.2L V-8 engines (2002 and newer)

This gasket is essential for maintaining proper exhaust system integrity and preventing exhaust leaks that could lead to reduced performance, corrosion, or dangerous exhaust gas intrusion. Designed for dry joint exhaust systems where the manifold and riser connection does not incorporate water cooling.
