6. Remove the old impeller, woodruff key, and any gaskets or wear plates.
7. Thoroughly clean the inside of the housing and the base plate, inspecting for any scoring or damage.
8. Install the new wear plate and gasket, applying a light coat of marine grease.
9. Slide the new woodruff key into the driveshaft keyway.
10. Lightly lubricate the new impeller with a soap-water solution and slide it onto the driveshaft, turning the shaft clockwise to bend the blades correctly.
11. Reinstall the water pump housing and torque the bolts to the manufacturer's specification.
12. Reassemble the lower unit, reconnect the shift linkage, and test the engine in water to confirm a steady stream from the tell-tale port.
