65 hp johnson gas oil mix?

Question

What is the ratio of mix on a 1972 65 hp johnson motor?

Answer 1

The mix when that motor was new was  1/2 pt to the gallon of leaded regular gas. Use 20 wt oil.

Answer 2

Yep, it's 50 to 1. I just bought one of those about a month ago. Mine is an Evinrude though, 65HP Triumph motor.  Yours should be identical to mine except for the name. If yours has the Hydro-electric shift, be sure you use the proper gear oil in the foot. Any old gear oil won't work.

Answer 3

It is 50:1

For your six gallon gas can add one pint of oil. Either brand specific or oil that is designated for outboard engines.

Jim: you have it mixing at approximately 16:1, that is WAY too much oil.
