Installation Guide

1. Safety First: Disconnect the battery and disable the ignition system before beginning work.
2. Access the Pump: Remove the lower unit (gearcase) from the outboard motor to access the water pump assembly.
3. Disassemble Housing: Carefully unbolt and remove the water pump housing. Note the orientation of all parts.
4. Remove Old Components: Take out the old impeller, gaskets, wear plate, and seals. Remove the impeller key from the driveshaft.
5. Clean Surfaces: Thoroughly clean all mating surfaces, removing any old gasket material or corrosion.
6. Install New Components: Place the new gasket, wear plate, and housing insert into position.
7. Lubricate and Install Impeller: Important: Lubricate the new impeller and the inside of the housing with silicone grease, glycerin, or dish soap. Slide the new impeller key into the driveshaft and install the impeller, turning the driveshaft clockwise to bend the vanes in the correct direction.
8. Reassemble: Install the new housing gasket and reinstall the water pump housing, tightening the bolts to the manufacturer's specified torque.
9. Reinstall Lower Unit: Reattach the lower unit to the outboard motor.
10. Test Operation: Reconnect the battery. Start the engine using a water supply (flushing muffs) and check for a steady stream of water from the tell-tale outlet. Never run the engine dry.
