I have a 2001 Honda 9.9HP as my kicker and it's been overheating. I opened up the water pump housing and the impeller was completely worn out, so I ordered a new one and changed it. For the 15-20 minutes or so, it ran fine and pumped a solid stream of water out the side, but after that, it pumped less and less water until I adjusted the idle screw so it idles very high. Finally, no more water...and it overheats. I opened up the water pump housing again and this time, the entire impeller melted and only the core was left.

Does anyone have any experience with this? Any thoughts on what it may be? Any help you can provide will be greatly appreciated!!!

FYI, I've purchased the Honda water pump kit and replaced everything, but it does it again and the impeller gets worn out.
