ratio is 16 ounces of oil per six gallons of fuel
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.
Hi All, I just bought one of these Evinrude 2.3 outboard the chap told me the fuel is 50/5o.
The mix ratio was probably 20-1 for the older motors due to the older technology oils, in any case the mix using the oil available today will be 50:1. works fine on our old 2 horse.
