Installation Guide

1. Disconnect the spark plug wire to ensure the engine cannot start during the procedure. Remove the lower unit from the outboard motor following your engine's service manual.
2. Locate the water pump housing on the lower unit. Remove the bolts securing the housing and carefully separate it to access the impeller.
3. Remove the old impeller from the shaft. Inspect the housing and wear plate for grooves, cracks, or damage; replace if necessary.
4. Lubricate the new impeller with glycerin, dish soap, or water pump grease—never use petroleum-based lubricants. Ensure all vanes are pliable and free from defects.
5. Install the new impeller onto the shaft, aligning the keyway properly. Rotate the impeller vanes in the direction of shaft rotation as you slide it into the housing.
6. Reassemble the water pump housing, ensuring all gaskets and seals are correctly positioned. Torque the bolts to the manufacturer's specifications.
7. Reinstall the lower unit onto the outboard motor, ensuring proper alignment of the driveshaft and water tube. Secure all mounting bolts.
8. Reconnect the spark plug wire and run the engine in a test tank or on-water to confirm proper water flow. Check for steady water discharge from the tell-tale indicator.
