Installation Guide
- Disconnect the fuel line and remove the lower unit from the outboard motor following your engine's service manual.
- Remove the old water pump housing cover by unscrewing the mounting bolts. Inspect and discard the old impeller and wear plate.
- Clean all mating surfaces thoroughly to remove old gasket material, corrosion, and debris.
- Install the new wear plate (66T-44323-00) into the pump housing, ensuring proper alignment with dowel pins.
- Lubricate the new impeller (6H4-44352-00) with glycerin or soapy water, then carefully insert it into the housing with blades oriented in the correct rotation direction.
- Insert the key (90280-03024) into the driveshaft slot, then slide the insert cup (63D-44322-00) over the impeller hub.
- Position the new gasket (63D-44316-00) on the pump housing and install the cover (63D-44312-00) with the grommet (663-44366-00) in place.
- Secure the cover using the four new bolts (90119-08M15), tightening them in a cross pattern to the manufacturer's torque specification.
- Replace the thermostat (6G8-12411-00) and its gasket (62Y-12414-00) in the powerhead cooling passage.
- Install the new fuel filter (61N-24560-10), oil filter (5GH-13440-60), and anode (67C-45251-00) in their respective locations.
- Reinstall the lower unit, ensuring the driveshaft engages properly with the impeller. Replace drain gaskets (90430-08020) and secure with the cotter pin (91490-30025).
- Reconnect the fuel line, perform a freshwater flush test, and verify water flow from the tell-tale indicator before launching.
Troubleshooting & FAQ
Q: How do I confirm this kit fits my Yamaha engine?
A: Cross-reference your engine's model and year with the compatibility table above. Verify the original part number (66T-W006A-00) matches your engine's service manual or existing component. If your model year falls within 2001–2024 for F25/FT25B/T25F/F30A series, this kit is the correct fitment.
Q: How often should I replace the water pump impeller and these components?
A: Yamaha recommends inspecting the water pump impeller every 100 hours of operation or annually, whichever comes first. Replace the impeller if you notice cracked blades, missing vanes, or reduced cooling performance. Filters, thermostats, and anodes should be serviced according to your engine's maintenance schedule—typically every 100–200 hours.
Q: What are the signs that my water pump needs immediate replacement?
A: Watch for reduced or no water flow from the tell-tale indicator, engine overheating alarms, steam from the powerhead, or loss of engine power. If you experience any of these symptoms, shut down the engine immediately and inspect the cooling system to prevent catastrophic damage.
Q: Does this kit include everything I need for a complete service, or do I need to order additional parts?
A: This kit contains 17 essential components covering the water pump rebuild, fuel filter, oil filter, thermostat, anode, and gear oil pump. For a full service, you may also need engine oil, gear oil, spark plugs, and a lower unit seal kit depending on your maintenance interval—consult your engine's service manual.
