This ratio is 40:1.
Using fully synthetic motorcycle 2 stroke oil, the ratio is 40:1. Ie, 40 parts of fuel to 1 part of oil. That means 25mls of oil to 1000mls, (1 litre), of fuel. That is the ratio all the time. Change the fuel air ratio if any problems with fuel fouling or lean running symtoms.

The 1987 model, 40 hp Mariner outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
Mac 310 fuel/oil ratio is 40:1
40:1 from what I've read
The ratio should be 40:1 unless you have installed aftermarket domes, in which case the ratio would be 32:1.
Using a 40:1 fuel mixture will not hurt anything. The first number is the oil so the lower that number the more oil you have. I prefer running close to the 40:1 mixture because it has more oil so lubricates better. Keep in mind however that the more oil you have to gas the more smoke you get.
