Installation Guide

1. Safety First: Disconnect the negative battery cable to prevent accidental starting.
2. Access the Lower Unit: Position the engine securely and remove the bolts connecting the lower unit (gearcase) to the upper casing.
3. Remove the Old Pump: Carefully lower the gearcase. Once removed, unbolt and detach the existing water pump housing.
4. Inspect and Clean: Remove the old impeller, wear plate, and gaskets. Thoroughly clean all mating surfaces, removing any old gasket material or corrosion.
5. Install New Components: Place the new gaskets and wear plate into position. Slide the new impeller onto the driveshaft, turning the shaft clockwise to bend the vanes correctly.
6. Install Housing: Lightly lubricate the inside of the new pump housing and install it over the impeller. Secure it with the provided bolts, tightening them to the manufacturer's specified torque.
7. Reassemble: Carefully guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube align correctly. Reinstall the mounting bolts.
8. Final Checks: Reconnect the battery. Start the engine using a flush-muzzle or in the water and check for a strong, steady stream from the tell-tale outlet, confirming proper operation.
