Installation Guide

1. Disconnect the fuel line and remove the engine cowling to access the lower unit. Ensure the engine is off and cool before beginning work.
2. Drain the lower unit oil by removing the drain plug and collecting the old oil in a suitable container.
3. Remove the propeller by taking out the cotter pin and unscrewing the propeller nut. Slide the propeller off the shaft.
4. Unbolt and remove the lower unit from the mid-section by loosening all securing bolts. Carefully separate the lower unit.
5. Remove the old water pump housing by unbolting it from the lower unit. Take note of component orientation for reassembly.
6. Clean all mating surfaces thoroughly, removing old gasket material, debris, and corrosion. Inspect for damage or wear.
7. Install the new impeller into the housing, ensuring the vanes face the correct direction per manufacturer specifications.
8. Position the new gaskets and seals onto the housing. Apply a thin layer of marine grease to the impeller for initial lubrication.
9. Install the new water pump housing assembly onto the lower unit, carefully aligning dowel pins. Secure with the provided bolts, tightening evenly in a cross pattern.
10. Replace the thermostat and gasket in the appropriate location. Install the new fuel filter and anode as indicated in your service manual.
11. Reattach the lower unit to the mid-section, ensuring proper alignment of the drive shaft. Torque all bolts to factory specifications.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Yamaha outboard?
A: Verify your engine model is F4 or F4A manufactured between 1999 and 2008. Check your existing water pump housing for OEM part number 6EE-W006A-00. If your model and year match but part numbers differ, consult the exploded parts diagram for your specific engine serial number before purchasing.

Q: How often should I replace the water pump and impeller?
A: Yamaha recommends inspecting the water pump impeller annually and replacing it every 2-3 years or 200-300 hours of operation, whichever comes first. Replace immediately if you notice reduced water flow, overheating, or visible impeller damage during inspection.

Q: What are the signs that my water pump is failing?
A: Common symptoms include weak or no water stream from the tell-tale (pee hole), engine overheating, steam from the cowling, reduced performance, or the engine alarm sounding. If you notice any of these signs, stop the engine immediately and inspect the cooling system.

Q: Does this kit include everything I need for a complete water pump service?

Q: Can I install this kit myself or do I need a professional?
