Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is turned off and cool.
2. Access the Pump: Remove the lower unit (gearcase) from the outboard by unfastening the mounting bolts.
3. Remove Old Pump: Unscrew the bolts securing the water pump housing and carefully lift it off the driveshaft.
4. Inspect and Clean: Take note of the old parts' orientation. Remove the old impeller, gaskets, and plates. Clean all mounting surfaces thoroughly.
5. Install New Components: Install the new Woodruff key, gaskets, and wear plates. Slide the new impeller onto the driveshaft, turning it clockwise to align the vanes correctly within the housing.
6. Secure Housing: Place the new housing over the impeller and fasten it with the new bolts, tightening them to the manufacturer's torque specifications.
7. Reassemble: Reinstall the lower unit onto the outboard, making sure the driveshaft and water tube are correctly aligned.
8. Test Operation: Reconnect the battery. Start the engine using a water source (flushing muffs) and check for a strong, steady stream from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific engine?

A: Please review the "Compatible Engine Models" table above. For Yamaha owners, we highly recommend using the official Yamaha Serial Number Guide to confirm your model and year before ordering.

Q: How often should I replace my outboard's water pump impeller and kit?

A: Common signs include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, or an alarm from the engine's temperature warning system.
