I am new to the site and new to boating. I've been wanting a boat since I was 12 years old and I just picked up a 1963 16' run about (unknown make) with an Evinrude starflite V 75383E. It runs well, but either the thermostat is bad or the impeller is bad or both. I am currently trying to find a service manual and the right parts to fix this issue. I would also like to give it a good tune-up and will be restoring it somewhat. Any words of wisdom or help would be much appreciated. I'll try to post photos soon.
