Troubleshooting & FAQ
Q: How do I confirm this gasket fits my Honda outboard?
A: Cross-reference your engine model and year with the compatibility table above. Verify that your original gasket matches OEM part number 19234-ZY6-000 by checking your engine's parts diagram or the part itself.
Q: How often should I replace the water pump impeller gasket?
A: Replace the gasket every time you service or rebuild your water pump assembly, typically every 2-3 years or 200-300 hours of operation, or sooner if you notice coolant leaks or overheating issues.
Q: What are the signs that my water pump gasket is failing?
A: Common symptoms include visible coolant leaks around the water pump area, overheating engine warnings, reduced water flow from the tell-tale (pee hole), or steam coming from the engine cowling.
