In 1971 the factory oil recommendations were updated again to 50 to 1.
To answer your question as to do people actual reduce the amount
of oil they run, I do. I run 3 oz per gal. (about 42 to 1) in most all my
motors and have been since the late 90’s.
Below are some I have on You Tube. The first one, 1928 Elto Speedster
is basically a parts built around 25 years ago to answer this question
for me. I don’t run it every year but when I do I’ll put between 45 to 55
gallons of fuel through it. All the motors posted on You Tube I have had
on a boat for a least a month except for the 1938 Mate. Most have made
it to the lake more than 1 summer. Most of my motors are pre. WW-II
bushing motors.
This is how I chose to find the answer to that question. I’m not trying
to tell anyone how much oil they should run. Just offering my experience.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
