Troubleshooting & FAQ
How do I confirm this gasket fits my exact engine model?
While this gasket fits a wide range of 25-60 HP Evinrude/Johnson models from 1980–2005, it is critical to verify. Compare the part numbers (0325211, 777939) to your service manual or existing part. Visually inspect the shape against our product images.
What are the signs of a failing water passage gasket?
Symptoms include engine overheating, visible water leaks around the exhaust plate area, or steam coming from the engine cowling. Poor engine performance or water in the cylinders can also indicate a failed gasket.
How often should this gasket be replaced?
This gasket does not have a fixed replacement interval. It should be replaced whenever the components it seals are disassembled for service, or if you notice any signs of a leak or failure.
Can I reuse my old gasket?
No. Gaskets are single-use components designed to crush and create a seal. Reusing a gasket will likely result in leaks and potential engine damage.
