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.
The mix ratio for a 1978 2 horsepower Evinrude outboard motor is typically 50:1, which means 50 parts gasoline to 1 part outboard oil. This ratio ensures proper lubrication and performance of the engine. Always refer to the owner's manual for the specific mix ratio recommended by the manufacturer.
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.
The correct compression ratio for a 1992 6hp Evinrude outboard motor is typically around 6:1. However, it's important to verify this with the specific model's manual, as variations can exist based on production changes or modifications. Maintaining proper compression is crucial for optimal engine performance and efficiency.
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.
