An Evinrude 25hp outboard, 1985 year model, requires a 50:1 fuel, to 2 cycle oil ratio. This is roughly one pint of 2 cycle oil, to six gallons of fuel.
The 1992 model, 15 hp Evinrude outboard would use a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
1 pint of oil for 6 gallons of gas 50/1 gas to oil mix
The late model 25 Evinrude suggests operating on a 100:1 ratio. I prefer the old time tested 50:1 ratio, one pint of two cycle oil, to six gallons of fuel. I have never seen an outboard powerhead failure, due to running a 50:1 mix.
The 1980 model, 15 hp Evinrude outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
It is a 50:1 ratio, that is 1 pint to 6 gallons
The 20 hp Mercury outboard requires a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
I believe it is 50 : 1 (16 oz. oil to 6 gallons gas)
The 1978 model, 75 hp Mercury outboard, requires a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
Johnson and Evinrude outboards manufactured prior to 1965, require a 24:1 ratio. This ratio works out to 5-6 oz. of 2 cycle oil per gallon of fuel.
50:1
