Want this question answered?
I have a 1972 85esl72 Johnson outboard motor and I use a 50:1 ratio.
50 - 1
The ratio is 50:1.
A 1986 year model 30hp Johnson outboard uses a 50:1 fuel to oil ratio.
A 1981 model, 140 hp Johnson outboard requires a 50:1 ratio.
50.1 ratio
50to1
The 1992 model, 28hp Johnson outboard performs well on a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
The fuel to oil ratio for a 1988 model, 8hp Johnson outboard, would be 50:1, six gallons of fuel, to one pint of two cycle oil.
The 2 stroke, 9.9hp Johnson outboard produced after 1966, requires a 50-1 ratio. This is roughly one pint of 2 cycle oil, to six gallons of fuel.
50:1 ratio ie. 100ml oil to 5l fuel
I wish I knew!
