The 1987 model, 25 hp Johnson outboard requires a 50:1 ratio. One pint of 2 cycle oil, to six gallons of fuel.
50:1
i run mine @ 50:1
A non-oil injected, 150 hp Johnson outboard, of the 2 stroke family would require a 50:1 ratio. This is roughly one pint of 2 cycle oil, to six gallons of fuel.
The fuel to oil ratio for a 1962 model Johnson outboard is 24:1.
50 parts gas 1 part oil so i pint of oil per 6 gallons of gas
50:1 oil mix is typical for outboard two-cycles. Some do a little more in the winter.
How Old? I have a 1980 2HP Johnson. The Ratio is 50:1
My twin cylinder 1965 Johnson 3hp uses a 50:1 gas:oil ratio.
Fuel /oil mix is 50:1
my Johnson seahorse 70hp runs pretty nice at 50:1 fuel to oil ratio (1 litre oil to 50 litres fuel)
I have a 1976 Johnson 115 and the ratio I use is 50 to 1. Rob, Dallas, TX.
