Installation Notes
- Disconnect the battery and shift the outboard into neutral.
- Remove the lower unit (gearcase) by unbolting it from the engine's midsection.
- Unbolt and remove the old water pump housing to access the impeller and wear plate.
- Thoroughly clean all mating surfaces and inspect the driveshaft for wear or damage.
- Install the new wear plate, gaskets, and insert cup into the housing.
- Slide the new impeller key onto the driveshaft and push the new impeller down while turning the shaft clockwise to seat the vanes.
- Position the new O-ring in its groove and reinstall the pump housing, tightening bolts to the manufacturer's specified torque.
- Reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube are correctly aligned.
- Once assembled, start the engine and verify a steady stream of water from the tell-tale outlet.
Troubleshooting & FAQ
How do I know if my water pump needs replacing?
Common signs include the engine overheating at idle or low speeds, a weak or inconsistent water stream from the "tell-tale" outlet, or visible cracks/damage to the old pump housing upon inspection.
What is the recommended replacement interval?
For optimal performance and to prevent overheating, inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use. Service intervals may shorten depending on operating conditions (e.g., frequent use in saltwater or sandy/silty water).
My exact engine model isn't listed. Will this kit fit?
This kit is specifically designed for the Yamaha models F75, F80, F90, and F100 as detailed in the compatibility table. Do not use it for other models, as internal dimensions can vary. Please verify your engine model before purchase to ensure proper fitment.
Any tips for inserting the new impeller into the housing?
To ease installation, you can apply a light coat of marine-grade grease or a soap-and-water solution to the inside of the housing. When sliding the impeller onto the driveshaft, turn the shaft clockwise (the normal direction of rotation) to help the flexible vanes fold correctly into the housing cup.
