The fuel mix is 24:1

50:1
im trying to find out what to mix the gas at for a 40 hp evinrude outboard motor
50:1
50:1
The 88 hp Evinrude, all models, requires a 50:1 ratio.
The 1981 model, 70 hp Evinrude, requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
The 25 hp Evinrude outboard has been designed to run a 50:1 ratio, for earlier models, and 100:1 for late model engines. Pre 1965 models run a 24:1 ratio.
50:1
Evinrude and Johnson outboards prior to 1965, require a 24:1 ratio, so the 64 model would be a 24:1 fuel to 2 cycle oil mix.
