Troubleshooting & FAQ
How many gaskets do I need for my engine?
Most V6 applications require two of these gaskets for a complete installation—one for each side of the exhaust divider plate. Always consult your service manual to confirm the quantity for your specific engine model.
What are common signs of a failed divider plate gasket?
Symptoms include audible exhaust leaks (a hissing or ticking sound), engine overheating, reduced performance, water intrusion into cylinders, or visible soot/corrosion around the exhaust plate area.
Is this part sold individually or in a pack?
This part is sold as a single gasket. Please verify the quantity needed for your specific repair and adjust at checkout.
Does this fit all Mercury V6 engines?
No. This gasket is specifically for certain 2-stroke V6 models (150-200 HP) from 1976–1988 and some earlier 2.4L models. It is critical to check the compatibility table and verify against your engine's part number before ordering.
