Sierra Crankcase Gasket 18-2512-9, Replaces Mercury 27-60286, 3 Cylinder, Pack of 5

The Sierra 18-2512-9 Crankcase Gasket seals the crankcase to the cylinder block on 3 cylinder outboard engines. It is sold as a package of five gaskets, giving you enough on hand for a full rebuild or for keeping spares for future service work. The gasket is made from a glass material formed into a round shape designed to seat properly against the mating crankcase and cylinder block surfaces, helping maintain a proper seal and prevent leaks between these two components.

Each Sierra 18-2512-9 gasket is built to meet or exceed the quality of the original equipment part it replaces, making it a reliable choice for engine maintenance and rebuild jobs. Because the crankcase-to-cylinder-block seal is critical to engine compression and oil containment, using a properly fitted replacement gasket like this one helps ensure a dependable repair. This part replaces Mercury 27-60286.
