- Remove the bolts securing the lower unit (gearcase) to the upper casing and carefully lower it.
- Unbolt and remove the water pump housing cover to access the impeller.
- Take note of the old impeller blade direction, then remove it and the woodruff key.
- Clean the housing interior and inspect it for wear, scoring, or corrosion.
- Install the new woodruff key and lubricate the new impeller with a light coat of grease or soapy water.
- Slide the new impeller onto the driveshaft, rotating it in the direction of engine operation to flex the blades correctly inside the housing.
- Reinstall the water pump housing, gaskets, and cover, ensuring proper torque on all bolts.
- Reattach the lower unit to the outboard, ensuring the water tube and shift shaft align.
- Refill the gearcase with fresh oil, re-start the engine using a water source, and confirm water is exiting the tell-tale port.
Troubleshooting & FAQ
How do I know if my impeller needs replacing?
Common signs of a failed or failing impeller include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alerts, or a noticeable drop in water pressure. Visual inspection may reveal cracked, brittle, or missing blades.
What is the recommended replacement interval for this impeller?
For most recreational boats, it is recommended to inspect the impeller annually and replace it every 1-2 years, regardless of visual condition. For boats used in saltwater or sandy/silty conditions, annual replacement is strongly advised.
Will this fit my F90 model from 2012?
Yes, this impeller is compatible with the Yamaha F90A model for years 2012 through 2017. Always cross-reference the OEM part number 67F-44352-00-00 to be certain.
What's the difference between 67F-44352-00-00 and 67F-44352-01-00?
The part number 67F-44352-01-00 is listed as a supersession or replacement for the original 67F-44352-00-00. Both are dimensionally and functionally identical, and this aftermarket part is designed to replace both versions.
Do I need to lubricate the impeller during installation?
Yes, applying a thin layer of marine grease or soapy water to the inside of the pump cup and the impeller blades helps prevent damage during the first dry start-up and makes installation easier.
