50-1
The ratio for the 2 stroke variety of the 1996 model, 9.9 hp Johnson outboard would be 50:1. This is roughly one pint of 2 cycle oil to six gallons of fuel.
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
40:1
The fuel/oil ratio is 50:1.
No no and no lol it is a two stroke and must be mixed 50:1 oil ratio .
The mixture ratio for Yamaha outboards is 50:1 gas/two stroke oil. That is approximately one pint of gasoline to a plastic coke bottle cap full of two stroke oil.
50 - 1
They are all 50 to 1
The 1988 model, 28hp Johnson outboard, requires a 50:1 fuel to oil ratio. This is roughly, one pint of 2 cycle oil, to six gallons of fuel. If you have the same motor I have which is a 1988 Johnson 28 hp 2 stroke then the mixture is 100:1. The answer provided above is wrong. This is 8 ounces of 2 stroke oil to 6 gallons of gas. I have had this motor since it was new and it still runs great today.
I have a 1972 85esl72 Johnson outboard motor and I use a 50:1 ratio.
Alot of these motors are automatic mixing motors but if yours is not the normal ratio is 6oz of oil to every gallon of gas.
