Sierra Shift Housing Gasket 18-0110-9, Replaces OMC 324670, Pack of 2, Evinrude/Johnson

The Sierra 18-0110-9 Shift Housing Gasket is a replacement gasket for the shift housing on Evinrude/Johnson outboard motors, sold as a pack of 2. It is built to meet or exceed the fit, form, and function of the original equipment part it replaces, sealing the shift housing to prevent water intrusion and lubricant loss at this joint. Because a worn or damaged shift housing gasket can allow water to enter the gearcase or let gear lubricant leak out, replacing it during a shift housing service, lower unit rebuild, or when a leak is found at this location helps protect the shift mechanism and gearcase from corrosion and lubrication loss.

Each gasket is manufactured to the same specification as OMC part number 324670, so it installs as a direct replacement without modification. Selling two gaskets per package means a spare is on hand for a future service, or two units can be used across two repairs, reducing the chance of a shop trip for a single part.
