Oil/Gas Mixture 1963 10 hp Johnson

I just purchased a boat with a 1963 10 hp Johnson, Model QD-24M and need to know the oil mixture for this.

24:1 according to the original OMC specs. That's 1 quart of oil for 6 gallons of gas, or 40ml of oil per litre of gas.<br />Use 87 octane (91 RON rated) and TC-W3 rated outboard oil.<br /><br />And welcome to Iboats!
