Installation Notes
- Disconnect the battery and remove the engine cover.
- Shift the outboard into neutral and remove the lower unit (gearcase) by unbolting it from the engine's midsection.
- Place the lower unit on a workbench and remove the bolts securing the water pump housing.
- Slide the old housing, impeller, and gaskets off the driveshaft. Note the orientation of the impeller fins.
- Clean all mating surfaces thoroughly, removing any old gasket material.
- Install the new woodruff key, gaskets, wear plate, and impeller. Rotate the driveshaft clockwise to seat the impeller fins correctly inside the new housing.
- Lightly grease the new bolts and tighten the housing to the manufacturer's specified torque.
- Reinstall the lower unit, ensuring the driveshaft and water tube align correctly.
- Reconnect the battery and test the engine using a water source (flushing muffs) to confirm proper water flow from the tell-tale outlet.
Troubleshooting & FAQ
How do I know if my engine's water pump is failing?
Common signs of a failing water pump include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, and reduced engine performance. A visual inspection of the old impeller may reveal cracked, brittle, or missing fins.
How often should I replace my outboard's water pump impeller?
For optimal reliability, it is recommended to inspect the impeller annually and replace the entire water pump kit every 1-2 years or every 100-200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater).
Will this kit fit a Yamaha F90 4-stroke model?
No, this kit is specifically designed for Yamaha 60-90 HP 2-Stroke outboards. It is not compatible with 4-stroke models. Please verify your exact engine model and year before ordering.
What's the most common mistake during installation?
A frequent error is installing the impeller with the fins facing the wrong direction. The fins should be oriented to bend back against the direction of the driveshaft's rotation (typically clockwise). Forcing the housing over incorrectly oriented fins can damage the new impeller immediately.
My engine model isn't listed, but the year and HP match. Will it fit?
We highly recommend matching your specific model number against the compatibility list. Manufacturers often make mid-year changes or have variations across models. If your model is not explicitly listed, we cannot guarantee fitment.
Do I need any special gaskets or sealants?
This kit includes all necessary gaskets and o-rings for a standard installation. No additional sealants are typically required, but you may apply a light coat of marine-grade grease to help position gaskets and ease assembly.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
