7. Install the new wear plate and gasket from the kit onto the gearcase.

9. Apply a light coat of marine grease to the inside of the new housing and install it over the impeller.
10. Securely reinstall the housing bolts to the manufacturer's specified torque.
11. Re-attach the gearcase, ensuring the driveshaft, shift shaft, and water tube are correctly aligned.
