found it 50 to one
16 to 1, or 1/2 pint per gallon
50:1 ratio
A 1973, 50hp Evinrude outboard uses a 50:1 fuel to oil ratio.
The proper mixture for that motor is 50:1. Approximately 2.56 oz. of oil to 1 gallon of gas.......5.12 oz. of oil to 2 gallons of gas....etc..
24:1
The Gas/Oil ratio is 50:1
I have a late 1960's Ted Williams air-cooled 7.5 hp outboard produced by Eska with the manual. The manual states 24:1. Hope it helps.
jonsered oil/gas mixture ratio is 50 to 1.
it is gas only no oil is added to the gas
