The Sierra 18-0799 Exhaust Cover Gasket is a high-quality aftermarket replacement gasket engineered to meet or exceed OEM specifications for Yamaha outboard motors. This gasket directly replaces Yamaha OEM part number 6E5-41112-A1-00, also known as the exhaust inner cover gasket, ensuring a precise, like-for-like fit.
Sierra gaskets are machined to perfectly match mating surfaces, giving both professional marine technicians and DIY mechanics the confidence that the repair will seal correctly the first time. The exhaust cover gasket plays a critical role in maintaining the integrity of the exhaust system and preventing the mixing of exhaust gases and cooling water—a common failure point in outboard motors operating in harsh marine environments.
Key Features:
It is best practice to replace the exhaust cover gasket any time the exhaust cover or surrounding components are removed for inspection or service. Sierra has been a trusted supplier of aftermarket marine engine parts for over 50 years, offering boaters and mechanics quality components at a proven value.
