    On May 3 1963 Scot issued service bulletin 352. In that they state that pre 1961 motors with full roller bearings can be run 40:1 with what was then Scott premium outboard oil. So, I will go out on a limb and say try 40:1 with either TCW3 or full synthetic. (See my other tests in an earlier post)

    THIS WAS SCOTT’S PUBLISHED RECOMMENDATION.
