50:1
The correct fuel oil ratio is 50/1.
50 : 1 using 87 octane fuel I have the same motor
The Johnson 75 hp Stinger model requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
A Johnson 48 special, 1989 year model, requires a 50:1 fuel to 2 cycle oil mix. This is roughly one pint of 2 cycle oil, to six gallons of fuel.
The 1982 model, 70 hp Johnson outboard, requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
The fuel to oil ratio for a 1977 model, 35 hp Johnson, is 50:1. This is roughly, one pint of 2 cycle oil, to six gallons of fuel.
The 1969 model, 55 hp Johnson outboard, requires a 50:1 ratio. One pint of 2 cycle oil, to six gallons of fuel.
all 2 stroke outboards are 50:1 Older Johnson Evinrudes are 24:1 (pre 1965) Some Mercurys are 40:1
Johnson/ Evinrude 2 cycle outboards after 1964 used a 50-1 gas oil mix.
Johnson outboards manufactured after 1964 require a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
A non-oil injected, 150 hp Johnson outboard, of the 2 stroke family would require a 50:1 ratio. This is roughly one pint of 2 cycle oil, to six gallons of fuel.
although the sticker on it says 100:1, mix a 50:1 ratio. In 1986 & 1987, for some reason Johnson went to a 100:1 recommendation. I actually like a 64:1 ratio in my pre mix 2 stroke outboards. That's 2oz of oil per gallon of gas.
