Replacing the water pump will take you about an hour to complete.
If your yamaha 90hp water pump has been neglected for some time it may also be necessary to replace.
I m installing a new water pump this time.
The water pump on your yamaha outboard motor has a special seal over the trim tab that you need to remove in order to access the bolts that hold the water pump in place.
The pump supplies the water that cools the entire engine.
