Installation Guide

1. Disconnect the fuel line and remove the engine cover to access the lower unit. Ensure the engine is completely cool before starting work.
2. Drain the lower unit gear oil by removing the drain and vent plugs. Disconnect the water pump hose connections.
3. Remove the lower unit mounting bolts and carefully separate the lower unit from the mid-section. Support the lower unit to prevent damage.
4. Remove the water pump housing bolts and lift off the housing to expose the old impeller. Take note of the impeller blade orientation.
5. Carefully extract the old impeller from the pump housing, checking for any broken blades or debris. Clean the housing thoroughly.
6. Lubricate the new impeller with water-resistant grease or glycerin to ease installation and protect the blades. Do not use petroleum-based lubricants.
7. Install the new impeller into the housing, ensuring all blades bend in the correct direction of rotation. Align the keyway with the drive shaft.
8. Reinstall the water pump housing and tighten bolts to the manufacturer's specified torque in a cross pattern. Ensure all gaskets and O-rings are properly seated.
9. Carefully reattach the lower unit to the mid-section, aligning the drive shaft splines. Tighten mounting bolts evenly.
10. Refill the lower unit with fresh gear oil to the proper level. Replace drain and vent plugs with new gaskets if needed.
11. Reconnect all water hoses and ensure secure connections. Double-check that all fasteners are tightened properly.
12. Test the cooling system by running the engine in a test tank or on muffs, confirming strong water flow from the tell-tale indicator.

Troubleshooting & FAQ

Q: How do I confirm this impeller fits my Honda engine?
A: Cross-reference your engine model and year with the compatibility table above. Verify that your current impeller matches OEM part number 19210-ZV5-003 to ensure proper fitment across all BF35AM through BF60A/BFP60A series engines.

Q: How often should I replace my water pump impeller?
A: Honda recommends inspecting the impeller annually and replacing it every 2–3 years or 200–300 hours of operation, whichever comes first. Replace immediately if you notice overheating, reduced water flow from the tell-tale, or any visible damage to the blades.

Q: What are the signs that my impeller is failing?
A: Common symptoms include weak or no water discharge from the tell-tale indicator, engine overheating, steam from the engine compartment, or an audible high-temperature alarm. Inspect the impeller immediately if you experience any of these issues.

Q: Can I use petroleum-based grease during installation?
A: No, never use petroleum-based lubricants as they can damage the rubber impeller blades and cause premature failure. Use only water-resistant marine grease, glycerin, or dishwashing liquid for lubrication during installation.
