Installation Notes

1. Disconnect the battery and place the engine in a stable service position. Follow the engine manufacturer's service procedure.
2. Drain the gearcase lubricant if required by the service procedure, then remove the lower unit while supporting its weight.
3. Remove the water pump housing and note the impeller vane direction before taking out the old impeller, key, wear plate, and gasket.
4. Clean the pump housing and mating surfaces. Remove old gasket material and inspect the housing, shaft, keyway, and wear plate for damage.
5. Install the new wear plate and gasket, fit the impeller key, and install the impeller in the correct direction for the engine's shaft rotation.
6. Reinstall the water pump housing and tighten fasteners to the manufacturer's specified torque.
7. Reinstall the lower unit, aligning the driveshaft, water tube, and shift mechanism. Secure all fasteners according to the service manual.
8. Refill the gearcase with the specified marine lubricant and test the engine in water. Confirm a steady cooling-water tell-tale stream.
