Troubleshooting & FAQ
Q: How do I confirm this O-ring fits my Honda outboard?
A: Check the compatibility table above for your engine model, horsepower, and year range. Verify that your original part number matches 91356-ZW1-B00 to ensure correct fitment.
Q: How often should I replace the water pump O-ring?
A: It is recommended to replace the water pump O-ring every time you service the water pump impeller, typically every 2–3 years or 200–300 hours of operation, whichever comes first.
Q: What are the signs of a failing water pump O-ring?
A: Common symptoms include reduced water flow from the tell-tale, engine overheating, loss of water pressure, or visible coolant leaks around the lower unit water pump housing.
