Sierra Exhaust Manifold Elbow Gasket 18-0305-1, Replaces 96108, for Crusader 18-1929/18-1933 Manifolds

This Sierra Exhaust Manifold Elbow Gasket, part number 18-0305-1, is the gasket that seals the connection between the exhaust manifold and the exhaust elbow on compatible Crusader marine engine setups. It is designed for use with Crusader exhaust manifolds 18-1929 (Starboard) and 18-1933 (Port), forming the seal that keeps exhaust gases and cooling water properly contained at the manifold-to-elbow joint. This gasket is also included as a component of the 18-8515 mounting kit, so buyers assembling or servicing that kit already have this gasket on hand and do not need to order it separately unless replacing a worn unit individually.

Keeping this gasket in good condition is important for preventing exhaust leaks and water intrusion at the manifold connection, both of which can lead to reduced engine performance, corrosion, or more serious cooling system issues if left unaddressed. At just 0.02 pounds, it is a lightweight, low-cost component that is inexpensive insurance against a failed seal during routine exhaust system maintenance or manifold replacement.
