Oil mix for 50s and and early 60s evinrude/ johnson

[hondaatc]

Anyone have a oil mix chart or cheat sheet for the evinrude/johnsons of the 50s and early 60s i have a few different sizes but most are from the 50s looking for the proper fuel mix I’ve been using 16.1 but I’ve been told its to much oil thanks

Here’s an Evinrude service data sheet that gives oil ratios for that year range of motors – Johnson motors of the same HP would be the same mix. Personally, I would stay with 16:1 on any motor before 1960 and 24:1 for motors 1960 thru 1963, just my thoughts.
