Installation Guide

1. Disconnect the Battery: Ensure the engine is off and disconnect the battery terminals to prevent accidental starting.
2. Remove Lower Unit: Drain the gearcase oil, then unbolt and carefully lower the outboard's lower unit (gearcase).
3. Access Water Pump: With the lower unit removed, locate and unbolt the water pump housing cover.
4. Remove Old Components: Take note of the order of parts. Remove the old impeller, wear plate, gaskets, and shaft key.
5. Clean Surfaces: Thoroughly clean the mating surfaces of the housing and plate, removing any old gasket material or debris.
6. Install New Components: Install the new gasket, wear plate, and shaft key. Slide the new impeller onto the driveshaft, turning the shaft clockwise to align the vanes correctly within the housing cup.
7. Reassemble Pump: Apply a light coat of marine grease or soap to the inside of the housing cup. Install the cup and new gasket, then tighten the housing bolts to the manufacturer's specified torque.
8. Reinstall Lower Unit: Reattach the lower unit to the outboard, ensuring the driveshaft and water tube align correctly. Refill the gearcase with fresh oil.
9. Test Operation: Reconnect the battery. Start the engine in water and verify a steady stream of water is exiting the tell-tale port, indicating the cooling system is functioning properly.
