Troubleshooting & FAQ

How do I confirm this gasket fits my specific Yamaha outboard model?

While this gasket is designed for the F200-F250 HP range (2005–2021), always check your engine's service manual or existing part number. This part directly replaces OEM part 6P2-41122-00-00 and WSM 523-31-01. Verifying against these numbers is the best way to ensure compatibility.

What are the symptoms of a failed exhaust inner cover gasket?

Common signs include a noticeable exhaust leak (hissing or popping sounds from the engine), decreased engine performance, overheating, or visible exhaust soot/stains around the cover plate area.

Is any sealant required during installation?

Generally, this type of gasket is designed to be installed dry. Always follow the specific instructions in your engine's service manual, but avoid using sealants unless explicitly required, as they can interfere with proper sealing or cause damage.

When should this gasket be replaced?

The gasket should be replaced whenever the exhaust inner cover is removed for service or maintenance. It should also be replaced immediately if you detect any signs of an exhaust leak to prevent further engine damage.
