Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is securely turned off and in a stable position.
2. Remove Lower Unit: Unbolt and carefully detach the lower unit (gearcase) from the outboard's upper casing.
3. Access the Pump: Locate and unbolt the water pump housing cover to expose the old impeller.
4. Remove Old Impeller: Take note of the blade orientation, then remove the old impeller, gaskets, and drive key.
5. Clean and Inspect: Thoroughly clean the inside of the pump housing and wear plate. Check for scoring or damage.
6. Install New Components: Place the new drive key onto the driveshaft. Slide the new impeller on, rotating the shaft clockwise to ease the blades into the housing.
7. Reassemble Pump: Install the new gaskets and O-ring, then securely bolt the housing cover back in place.
8. Reinstall Lower Unit: Carefully guide the lower unit back into place, ensuring the driveshaft and water tube align correctly. Fasten all bolts to the manufacturer's torque specifications.
9. Test Operation: Reconnect the battery. Start the engine in a water supply (using flush muffs or in the water) and confirm a steady stream of water from the "tell-tale" outlet.

Troubleshooting & FAQ

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

A: The best way to ensure compatibility is to verify your engine's model and year against the lists in the "Compatible Engine Models" section. Cross-referencing your existing part number with those in the "Part Number Cross-Reference" table is also highly recommended. For Yamaha owners, our Yamaha Serial Number Guide can help you identify your model details.

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

A: The most common symptom is engine overheating, especially at idle or low speeds. Other signs include a weak or non-existent water stream from the tell-tale port, or finding brittle, cracked, or melted rubber blades during a physical inspection.

Q: How often should I replace the impeller?

A: For preventative maintenance, it is recommended to replace your water pump impeller every 1 to 2 years or every 100-200 hours of operation, whichever comes first. This schedule can vary based on usage conditions (e.g., saltwater vs. freshwater, sandy/silty water).
