First, in 1979, Johnson made a 90, 115 and 140. If you really have a 135hp, then its year is 1973-1976. The oil ration is 50:1
The 1979 model, 115 hp Johnson outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
50:1 Which is one pint for six gallons of gas
50:1 is the correct mixture.
I use a 50:1 mixture in my 9.9 Johnson
fuel oil mixture 40:1 a good rule is to mix all outboards no matter what horse power a pint to 5 gallons
50 to 1
50:1
50:1
50:1
50:1 is the correct mixture for a 1992 Johnson 60 hp outboard.
can someone tell me what the gas to oil mixture for a 48 spl Johnson boat motor is please
enough oil is what you need
