Sierra Inner Exhaust Cover Gasket 18-0102, Replaces OMC 326264, for Johnson/Evinrude Outboard Motors

The Sierra 18-0102 is an inner exhaust cover gasket built for Johnson and Evinrude outboard motors. It seals the inner exhaust cover against the powerhead, preventing exhaust leaks and maintaining proper cooling water and exhaust routing through the outboard's exhaust housing. This gasket is a direct replacement for OMC part number 326264, letting you restore a factory-tight seal without sourcing the original OMC part.

The gasket is finished in white and is sold individually (package quantity of 1), so you can order exactly the quantity your job requires. It is manufactured in the United States and carries Sierra's limited warranty. As with any exhaust or cover gasket, this is a wear item that should be replaced any time the inner exhaust cover is removed, since reusing an old gasket risks an incomplete seal and exhaust or water leakage.
