Sierra Exhaust Cover Plate Gasket 18-2741 for Mercury Outboard Engines

The Sierra Exhaust Cover Plate Gasket, part number 18-2741, is a replacement gasket designed to seal the exhaust cover plate on Mercury outboard engines. It creates a tight, leak-free seal between the exhaust cover plate and the engine housing, helping to prevent exhaust gas and water leakage at this joint during operation. The gasket is round in shape and finished in a multi-colored appearance typical of composite gasket material construction.

This is a single-piece gasket sold individually, intended as a direct maintenance replacement part for the exhaust cover plate assembly on applicable Mercury outboard engines. Because gaskets compress and can lose their sealing ability over time or after a cover plate has been removed for service, replacing the gasket with a new Sierra 18-2741 whenever the exhaust cover plate is taken off helps maintain a proper seal and avoid leaks.
