Installation Guide

1. Safety First: Before starting, disconnect the engine's battery cables to prevent accidental starting.
2. Access the Lower Unit: Place the outboard motor in a secure, upright position. Remove the bolts that attach the lower unit (gearcase) to the upper leg of the motor.
3. Remove the Water Pump Housing: With the lower unit separated, locate the water pump assembly. Unscrew the bolts securing the water pump housing cover and lift the cover off.
4. Inspect and Remove Old Impeller: Note the orientation of the blades on the old impeller before removing it. Pull the old impeller off the driveshaft. Remove the old key from the driveshaft.
5. Clean and Inspect: Thoroughly clean the inside of the pump housing and the base plate. Inspect the housing and cover for any cracks, melting, or scoring. Replace if damaged.
6. Install New Impeller: Insert the new key into the keyway on the driveshaft. Slide the new impeller onto the shaft, aligning its keyway with the key.
7. Seat the Blades: Apply a light coat of marine grease or a soap-and-water solution to the inside of the pump housing. Place the housing over the impeller and press down while turning the driveshaft clockwise to correctly bend the blades into position.
8. Reassemble and Tighten: Secure the water pump housing with its bolts, tightening them to the manufacturer's specified torque.
9. Reinstall Lower Unit: Guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube are properly aligned. Re-install and tighten the mounting bolts.
10. Test Operation: Reconnect the battery. Start the engine using a water supply (flushing muffs or in a test tank) and check for a steady stream of water from the cooling system's tell-tale port.
