1977 70hp Evinrude is still overheating after replacing the impeller, Checked thermostat (OK) & flushed from the pickup tube to thermostat. When running the motor, Water does not come out of the outlet but I can see no obstructions anywhere. (I wasn't able to effectively flush the return side...
I ordered a water pump Kit for my 1977 Evinrude<br />70hp from NAPA, PN 183389.<br />I see that the impeller has a different type of<br />keyway, then I noticed that the box is marked for <br />1979-88 70hp. Now what do I do? Can this<br />impeller be used on my 1977 motor?<br /><br />Oh! btw...
