Installation Notes

Disconnect the battery and ensure the engine is completely cool.
Carefully remove the engine cowling to access the exhaust cover.
Locate and unbolt the exhaust cover assembly. Note the position and torque of each bolt.
Remove the old gasket, taking care to clean any residual material from both the engine block and cover mating surfaces. Use a plastic scraper to avoid gouging the metal.
Position the new gasket correctly on the engine block.
Reinstall the exhaust cover, tightening the bolts in a crisscross pattern to the manufacturer's specified torque to ensure an even seal.
Reconnect the battery and test the engine for exhaust leaks around the cover.

Troubleshooting & FAQ

How do I know if this gasket will fit my specific outboard model?

This gasket is designed for a range of OMC, Johnson, Evinrude, and BRP outboards that use part number 317914. Since specific model and year compatibility data is limited, the best way to confirm fitment is to match your old part's number and appearance to the images and specifications provided.

What are the signs of a failed exhaust cover gasket?

Common signs include a visible exhaust or water leak around the exhaust cover, an unusually loud engine noise, a rough idle, or a decrease in engine performance. A visual inspection may reveal black soot or water stains near the cover.

Is any sealant required when installing this gasket?

In most cases, this gasket is designed to be installed dry without any additional sealant. However, always consult your engine's specific service manual for the recommended procedure, as some models may require a light application of a specific sealant.
