Reply To: Mercury KE4 impeller help needed

[Anonymous]

Tested the impeller this morning running the lower unit under water powered by my drill and it was pumping water. Spoke with Dave and began tearing into the engine to look for impeller fins. Found two impeller blades lodged in the lower cylinder water jacket where the tube comes up from the lower unit. Was excited to finally find the source of the overheating. Cleaned everything up, flushed everything, blew air through everything and put everything back together. Took a good part of the day. Fired it up and was spitting water out of top three holes. I was relieved but that didnt last long, about 20 seconds into running it quit spitting water again. I guess there is another impeller somewhere in the water jackets that I didnt get out. For now im just gonna put her on the shelf and wait until i have more time to tear it down farther. Thanks for all the help i will give an update when I get started on it again.
