Troubleshooting & FAQ
How do I confirm this gasket fits my specific engine?
This gasket fits a wide range of Mercury/Mariner 70-85 HP, 3 & 4-cylinder outboards. The best way to confirm fitment is to match your engine's serial number with the ranges listed in the "Engine & Model Compatibility" table.
The compatibility chart lists serial numbers, not model years. How can I find my engine's year?
Outboard manufacturers often use serial numbers for precise part matching. You may need to consult a Mercury serial number reference guide (available online) or an authorized dealer to correlate your serial number to a specific production year.
What is this gasket's primary function?
This gasket is designed for use in carburetor linkage and choke solenoid assemblies, creating a secure seal to prevent air or fuel leaks, which is critical for proper engine performance.
What are symptoms of a failed carburetor gasket?
Signs of a faulty gasket include fuel leaking from the carburetor, a rough or unstable idle, engine stalling, difficulty starting, or poor acceleration. A visual inspection may also reveal cracks or degradation of the old gasket.
