Installation Guide

1. Disconnect the negative battery cable to prevent accidental starting.
2. Place the outboard in neutral and remove the bolts securing the lower unit (gearcase) to the engine's midsection.
3. Carefully lower and separate the gearcase from the driveshaft housing.
4. Locate the water pump housing on top of the gearcase and remove its mounting bolts.
5. Lift the housing to expose the old impeller. Note the rotational direction of the existing impeller vanes.
6. Remove the old impeller, driveshaft key, O-ring, and gasket. Thoroughly clean all mating surfaces.
7. Install the new O-ring and place the new gasket onto the gearcase.
8. Insert the new impeller key into the driveshaft slot. Slide the new impeller down the shaft while turning it clockwise to seat the vanes correctly inside the pump cup.
9. Reinstall the water pump housing and tighten the bolts to the manufacturer's specified torque.
10. Carefully guide the driveshaft and shift shaft back into the engine as you reinstall the lower unit. Secure it with the mounting bolts.
11. Reconnect the battery cable. Start the engine using a water supply (flushing muffs) and confirm a steady stream of water from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Honda engine?
A: This kit is designed for Honda BF8D, BF9.9D, BF15D, and BF20D series outboards. Please check the "Compatible Engine Models" table to verify your specific model and year. It's also critical to cross-reference the OEM part number 06192-ZW9-A30 with your existing part.

Q: My engine has a 25" extra long shaft. Will this kit fit?
A: There is conflicting information from different suppliers regarding shaft length compatibility. Some data indicates this kit fits extra long (25") shafts, while other sources state it will not. To ensure a correct fit, we strongly recommend verifying the required OEM part number for your specific engine's serial number before purchasing.

Q: What are the common signs of a failing water pump impeller?
A: The most common indicators include the engine overheating, a weak or non-existent water stream from the "telltale" cooling outlet, or finding that the old impeller's rubber vanes are cracked, brittle, or have broken off during inspection.

Q: How often should I replace the water pump impeller?
A: As a preventative maintenance measure, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of operation. Replacement intervals should be shorter for engines used frequently in saltwater or silty/sandy conditions.
