Installation Notes
- Disconnect the negative battery cable for safety.
- Place a drain pan beneath the lower unit and remove the drain plug to empty the gearcase oil.
- Remove the bolts that secure the lower unit (gearcase) to the midsection of the engine. Carefully lower it and place it on a workbench.
- Unscrew the bolts holding the water pump housing cover and remove it.
- Slide the old impeller off the driveshaft. Remove the old wear plate, gaskets, and insert cup, making note of their order and orientation.
- Thoroughly clean the grooves and mating surfaces of the housing and plate.
- Install the new gaskets, wear plate, insert cup, and impeller key from the kit.
- Lightly lubricate the new impeller with marine grease and install it, rotating the driveshaft clockwise to seat the vanes correctly.
- Reinstall the water pump housing, ensuring a proper seal, and reassemble the lower unit to the engine.
- Refill the gearcase with fresh marine gear lube before starting the engine.
- Reconnect the battery and test the engine in the water, confirming a strong, steady stream from the tell-tale outlet.
Troubleshooting & FAQ
What are the signs of a bad water pump impeller?
Common signs include the engine overheating at idle or low speeds, a weak or non-existent water stream from the tell-tale outlet, and visible damage like cracked or broken vanes on the old impeller upon inspection.
How often should I replace my outboard's impeller?
For preventative maintenance, it is recommended to inspect and/or replace the water pump impeller every one to two years, or every 100-200 hours of operation, depending on usage conditions (e.g., more frequently in saltwater or sandy/silty water).
Will this kit fit my specific F90 model engine?
This kit is designed for a broad range of Yamaha F75-F100 models from 1999-2017. To ensure a perfect match, please cross-reference your engine's model number and year against the detailed compatibility table provided above.
Does this kit include the water pump housing?
No, this is a water pump repair kit that includes the impeller and internal wear parts (cup, plate, gaskets, etc.). It is designed to rebuild your existing water pump housing. If your housing is cracked, warped, or corroded, it should be replaced separately.
Is it difficult to install this kit myself?
The installation is a moderately involved process that requires basic mechanical tools and knowledge. If you are not comfortable removing the lower unit of your outboard, we highly recommend professional installation to ensure correct assembly and prevent damage.
