Troubleshooting & FAQ
How do I know if this gasket will fit my exact Johnson/Evinrude model?
The best way to ensure compatibility is to match your original part number to the ones listed in our Part Number Matrix. While this part fits a general 20-35hp range, confirming the part number (326264 or 777467) from your service manual or the old part is critical.
What are symptoms of a failing inner exhaust cover gasket?
Common signs of a bad gasket include visible exhaust or water leaks around the cover, an unusual engine noise (hissing or popping), and potential engine overheating or performance issues due to improper exhaust pressure.
Should I use gasket sealant or adhesive with this part?
Generally, this type of gasket is designed to be installed dry without any additional sealant. Applying sealant can sometimes cause it to slip or not seal properly. Always consult your official service manual for your specific engine model's recommendations.
