2. Remove the lower unit (gearcase) from the outboard by unbolting it.
3. Unbolt and carefully remove the water pump housing cover.
4. Take out the old impeller, wear plate, and any gaskets. Note the rotational direction of the existing impeller's vanes.
5. Thoroughly clean all surfaces of the pump housing and wear plate, removing any old gasket material or corrosion.
6. Install the new components in reverse order: gasket, plate, impeller key, and new impeller.
7. Lubricate the new impeller and the inside of the housing with a suitable marine grease.
8. Slide the housing over the new impeller, turning the driveshaft clockwise to help seat the vanes correctly.

10. Reinstall the lower unit, carefully aligning the driveshaft splines and water tube.
11. Reconnect the shift linkage and battery, then test the engine with a reliable water source (like muffs) to confirm a strong tell-tale stream.
