oil/gas ratio please

[rustyzipper]

I have a 1969 Evinrude "Big Twin" outboard. Model # 40953 = no manuals.

How many onces per gallon?

Also back in 1969 I'm not sure if they even made unleaded fuel. Is no lead OK to use in this engine?

Thanks....

50:1. One pint in six gallons of fuel. Unleaded is just fine...it always was. Two-strokes don't need lead as a lubricant for valves, because they don't have valves.

Appreciate the info CATransplant. Quite apparent, I'm new to the boating world. :redface:
