Learn how to change the water pump on a Yamaha outboard motor in this video from Boats.net. We’re going to remove the lower unit, disassemble the water pump, and use a Yamaha 90HP outboard water pump kit to make our repair.

We’ll show you how to remove the lower unit and then take your water pump apart. On our motor, the impeller was torn, so we’re going to replace it along with the other gaskets included in the Yamaha 90TLR water pump kit. When you replace the upper water pump housing, be careful not to overtighten the bolts. The housing is made of nylon and can crack if overtightened.

Once we replace the water pump on our Yamaha outboard, we’ll show you an easy way to get the lower unit back on your motor and reinstall the trim tab.
