I have a 1975 evinrude 40 hp model number 40555c. I just put a new carb kit and water pump kit on it and now I want to know how much it is worth. Don't tell me to look at the NADA value either. Tell me how much you would ask if you were the one selling it. I just sold a 75 evinrude 25hp two months ago for $450, so a 40hp should be worth $800, right?
