Installation Guide

1. Safety First: Disconnect the battery and remove the engine cover. Shift the outboard into neutral.
2. Access the Lower Unit: Remove the bolts securing the lower unit (gearcase) to the upper leg of the outboard. Carefully lower and separate it.
3. Remove the Pump Housing: Locate the water pump assembly on top of the gearcase. Unbolt and lift the housing to expose the impeller.
4. Inspect and Remove Old Parts: Take note of the impeller's rotational direction. Remove the old impeller, gaskets, and O-ring. Thoroughly clean any corrosion or debris from the housing and mating surfaces.
5. Install New Components: Place the new driveshaft key into the shaft. Apply a suitable marine lubricant to the new impeller and inside the housing. Slide the new impeller onto the driveshaft, turning it in the correct rotational direction to seat the vanes.
6. Reassemble: Install the new gaskets and O-ring. Securely bolt the water pump housing back in place according to torque specifications.
7. Reattach Lower Unit: Carefully guide the lower unit back into position, ensuring the driveshaft and water tube align correctly. Fasten the bolts securely.
8. Final Check: Reconnect the battery. Start the engine in the water or with a proper flush attachment and verify that water is exiting the tell-tale port, indicating successful pump operation.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Honda outboard?

A: Check the "Compatible Engine Models" table on this page. Your engine's model (e.g., BF8D, BF10D), HP, and year range should match the listings. Cross-referencing your existing part number with those in the "Part Number Cross-Reference" table is also a reliable way to confirm fitment.

Q: Does this kit include the water pump housing?

A: No, this is an impeller service kit that does not include the metal housing. It is intended for situations where your existing housing is in good condition and only the internal wear parts (impeller, gaskets, key, O-ring) need replacement.

Q: What are the signs of a failing water pump impeller?

A: Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, and reduced engine performance. A physically brittle, cracked, or deformed impeller upon inspection also indicates it's time for a replacement.

Q: How often should I replace the water pump impeller?

A: As a general maintenance rule, it is recommended to inspect and/or replace your water pump impeller every 1-2 years or every 100-200 hours of use, depending on operating conditions (saltwater vs. freshwater) and manufacturer recommendations.
