Sierra Shift Housing Gasket 18-2855-9, Replaces 304764, Johnson/Evinrude Outboard, Pack of 2

The Sierra 18-2855-9 Shift Housing Gasket seals the shift housing on Johnson and Evinrude outboard applications, preventing water intrusion and maintaining proper sealing at the shift mechanism housing joint. This gasket is sold as a package of two, giving you a spare on hand for a future service or allowing you to complete two repairs from a single package.

As a direct-fit replacement, this gasket restores the factory seal at the shift housing without requiring modification to surrounding components. Each Sierra gasket is manufactured to meet or exceed the specification of the original equipment part it replaces, so fit and sealing performance match what the outboard was originally designed around.

This part is intended for outboard owners and marine technicians performing shift housing service, gasket replacement during a rebuild, or routine maintenance where the old gasket has hardened, torn, or begun to leak. Because gaskets are a wear item that should not be reused once removed, keeping a package like this on hand simplifies the job when the housing needs to be opened.
