i have an old evinrude i think it is between 1965-1967. The only markings i can find id=s the serial #. It is 18502S-09564. I want to go fishing but dont know the fuel mixture any help is appreciated.
Re: trying to find what horsepower and fuel mixture for old evinrude
18502 is the model number and indicates its an 18hp. 09564 is the serial number. 18502 is indeed a 1965 and the 50:1 ratio previously mentioned is correct.<br /><br />-John
