Hi All, I just bought one of these Evinrude 2.3 outboard the chap told me the fuel is 50/5o.
50:1
50 to 1
50 to 1
For the 1990 model, 25 hp Evinrude outboard, use a 50:1 ratio, roughly 1 pint of 2 cycle oil, to six gallons of fuel.
25hp
The 1971 model, 125 hp Evinrude 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.
That model number would be for a 1984 10 horse evinrude. If it is a 15 horse now than someone has replaced the original powerhead.
