Re: Two stroke mix for 1965 3hp Evinrude
Originally it's specified as 50:1 87 octane gas (91 RON or better) to TCW-3 rated outboard oil. But 40:1 is much better for that particulair engine. A little more smoke, but the connecting rods stay inside the engine better.<br />Those are really nice engines, by the way. <br />Good luck!
