what year is my outboard and what gas to oil ratio do i need?

[SkaterBoy8034]

I have a 15 horsepower johnson, with the serial number E3993585 and the model number 15RL74S. What is the year of this outboard and what gas to oil mixture will work best?

Hey SkaterBoy...How goes it?<br /><br />Yer engine is a 1974. 50:1 mix (16oz. oil to six gal of gas) will do just fine.
