Sierra Exhaust Cover Gasket 18-2714, Replaces 27-414995, for 15-25 HP 2 Cyl Outboards

The Sierra 18-2714 Exhaust Cover Gasket is a replacement gasket designed to seal the exhaust cover on 15-25 HP, 2 cylinder outboard engines. It creates the seal needed between the exhaust cover and powerhead to prevent exhaust leaks and maintain proper engine sealing during operation. As a direct replacement part, it is sized and shaped to match the original equipment gasket it replaces, allowing for a straightforward swap during routine maintenance or when servicing the exhaust cover assembly. Keeping this gasket in good condition is important for preventing exhaust gas or water leaks at the cover joint, which can affect engine performance and longevity. This gasket is intended for one-time use during installation; once removed, the original gasket should not be reused, and a new Sierra 18-2714 should be installed to ensure a proper seal. It is a lightweight, compact component at 0.02 pounds, making it an inexpensive but essential part of a complete exhaust cover service. Boat owners and marine technicians performing exhaust cover maintenance, gasket replacement during a rebuild, or troubleshooting an exhaust leak on a compatible 15-25 HP, 2 cylinder outboard will find this gasket to be the correct fit for the job.
