Sierra 18-0418 Exhaust Manifold Mounting Gasket, Replaces Crusader 96653, for Manifold 18-1898

The Sierra 18-0418 is an exhaust manifold mounting gasket engineered to seal the connection between the exhaust manifold and engine block on applicable inboard/sterndrive setups. It is built to meet or exceed the quality of the original equipment part it replaces, giving installers a reliable seal that resists the heat and combustion byproducts present at the manifold mounting joint. This gasket is designed for use with Manifold 18-1898, so it is a direct fit when servicing or replacing that manifold assembly.

As a mounting gasket, its job is straightforward but critical: maintain a tight, leak-free seal at a high-heat, high-vibration joint so exhaust gases and cooling water stay contained within the manifold system. Sierra manufactures this part to original-equipment specifications, making it a straightforward drop-in replacement for the OEM gasket it supersedes. At 0.23 pounds, it ships as a single-count gasket ready to install during routine manifold service, gasket replacement, or a full exhaust system rebuild.
