Installation Guide
- Ensure the engine is off and the battery is disconnected. Shift the outboard into the neutral position.
- Remove the bolts securing the lower unit (gearcase) and carefully lower it from the driveshaft housing.

- Slide the old pump housing up and off the driveshaft, then remove the old impeller, key, and gaskets.
- Thoroughly clean the mating surfaces of the pump housing and base plate.
- Install the new gaskets and insert the new drive key into the driveshaft.
- Slide the new impeller onto the driveshaft, rotating it clockwise to align with the key and seat it correctly.
- Reinstall the water pump housing and tighten the bolts to the manufacturer's specified torque.
- Carefully guide the lower unit back into position, ensuring the driveshaft, shift shaft, and water tube align correctly. Securely fasten the mounting bolts.

Troubleshooting & FAQ

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