Troubleshooting & FAQ
How do I confirm this gasket fits my engine?
This part is primarily for Johnson/Evinrude 2-cylinder loopcharged engines (1990s–2000s). The most reliable way to confirm fitment is to match your old part number to one of the equivalents listed in our Part Number Matrix, such as Johnson/Evinrude 0351019 / 351019 or Mercury 878635.
What are the signs of a failing exhaust gasket?
Common symptoms of a blown gasket include a noticeably louder exhaust noise, reduced engine power, visible black soot trails around the gasket area, or an exhaust smell in the engine compartment. These signs indicate that the seal is compromised and should be replaced.
Can I reuse my old gasket or should I use sealant?
No, gaskets are designed for a single use and should never be reused. They crush to create a unique seal. Reusing one will almost certainly result in a leak. In general, this type of gasket should be installed dry on clean surfaces; do not use sealant unless your specific service manual requires it.
When should this gasket be replaced?
This gasket should be replaced any time the components it seals are separated for service. It should also be replaced immediately if you detect any signs of an exhaust leak, such as unusual noise or soot.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
