I just acquired an evinrude E15RCIS from a deceased relative

50:1

50:1 or about 2.5 ounces per gallon is the most common mixture

2.6 oz per gallon..on my late 70's early 80's omc's i use an extra capfull or so to give a lil added lubrication but youll foul plugs a lil faster especially if you troll alot..but 3 dollar plugs are cheaper than a new motor imo
