So I need to put in a new impeller on my motor, wondering where you can buy it and if there is anything specific you need to know or ask before getting one?
I just changed mine. I ordered it from iboats.com. I ordered it Sunday afternoon and it was delivered Wednesday. When you order, order the water pump kit. My motor was a Yamaha 40.hp. I was very happy with the parts . The parts were exact image as the original.

I just replaced the water pump on my mercury. I got the replacement kit for around $25 from wholesalemarine.com. The kit comes with a new impeller, gaskets, top and bottom water pump cover, and water tube. I changed out my thermostats and plugs too. If your changing the water pump its a good idea to change the thermostat if your motor has them. My impeller still looked in ok shape, but with the change the pressure gauge shows almost double the water pressure.
