I have a 1990 evinrude 6 hp which I've been working for a long time. And when I started it up this year, it overheated . I then took the water pump apart. I found the impeller pretty well disintergrated with a lot of material melted to the inside of the outlet going to the water tube . In fact the melted material was blocking the outlet to the water tube,I then cleaned this outlet up real good. I tried the motor and got no water cooling . I then ran a wire hanger up the water tube and felt some resistance. which later was released by running the wire up the tube. I now feel metal when i run the wire up and down the tube, but the motor continues to not have water cooling, can I have a blockage in the powerhead water jacket?? Any insight which you can relay to me would be appreciated.
