It depends on the year and specific model of engine. On an engine before the 1990's it's probably 50 to 1, after that could be 20 to 1. The best thing to do is do a search online for the engine model and year and find the service manual or owners manual. That will give you the correct ratio. Also if this is an older engine ask on one of the website Fiberglassics, iboats, or The Hull truth.
50:1 is the correct mixture for a 1992 Johnson 60 hp outboard.
50:1
50 to 1 oil to gas
50 to 1 or 2oz of oil to 1gallon of gas
enough oil is what you need
1 quart of outboard / 2 cycle motor oil to 6 gallons of gas
probably 50:1
The ratio is 50:1.
A 1981 model, 140 hp Johnson outboard requires a 50:1 ratio.
Gas/Oil mix for this motor is 50/1,using TCW rated oil.
50 to 1
The oil mixture for that motor is 1 pint of oil to 6 gallons of gas
