Installation Guide

  1. Safety First: Disconnect the negative battery cable before starting work.

  3. Disassemble: Carefully unbolt and remove the old water pump housing assembly. Note the order of the components.
  4. Remove Old Parts: Take out the old impeller, keyway, wear plate, gaskets, and seals.
  5. Clean Surfaces: Thoroughly clean all mating surfaces, removing any old gasket material or corrosion.
  6. Install New Components: Place the new gasket and wear plate onto the gearcase. Insert the new keyway into the driveshaft.
  7. Install Impeller: Slide the new impeller onto the driveshaft, turning it clockwise to bend the vanes correctly.
  8. Reassemble Housing: Install the new seal in the housing, place the housing over the impeller, and fasten it with the bolts.
  9. Torque Bolts: Tighten the housing bolts to the manufacturer's recommended torque specifications.
  10. Reinstall Lower Unit: Reattach the lower unit to the outboard motor.
  11. Test Operation: Reconnect the battery. Start the engine using a water supply (flushing muffs) and check for a steady water stream from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my engine?

A: The most reliable method is to check your engine's model, horsepower, and serial number against the detailed compatibility tables on this page. This kit is a direct replacement for several OEM part numbers, including Mercury/Mariner 47-43026Q06 and Honda 19021-ZW1-003. For Mercury owners, our linked serial number guide can help you verify your model.

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

A: The most common symptom of a bad impeller is engine overheating, often indicated by a warning alarm or gauge. Other signs include a weak or no water stream from the engine's "tell-tale" outlet, or an impeller that appears brittle, cracked, or has melted vanes upon inspection.

Q: How often should the impeller be replaced?

A: As a general maintenance rule, it is recommended to inspect the impeller annually and replace it every 1 to 2 years, or after every 100-200 hours of operation. Replacement frequency may depend on usage conditions, such as operating in saltwater or sandy/silty water, which can accelerate wear.
