Troubleshooting & FAQ
How do I confirm this gasket fits my engine?
The surest method is to match your existing part number to the ones listed in our Part Number Matrix (Parsun PAF8-04000006, Tohatsu 3B2-65029-0, etc.). You can also check your engine model against the compatibility table provided. When in doubt, compare our product photos to your old part.
What are the signs of a failing water pump gasket?
Common symptoms include the engine overheating, a weak or non-existent stream of water from the tell-tale port, or visible water leaks around the water pump housing seam on the lower unit.
When should I replace my water pump gasket?
It is best practice to replace the water pump gasket whenever you service the water pump or replace the impeller. A typical service interval is every 1-2 years or every 100-200 hours of operation, depending on use and water conditions (saltwater vs. freshwater).
Can I reuse my old gasket if it looks okay?
No. Gaskets are single-use components that compress to create a seal. Reusing an old gasket will likely result in a poor seal, leading to leaks and potential engine overheating.

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.
