1976 Evinrude 15hp. Fuel questions?

[merkdawg0084]

Not sure if this question belongs here? If so please move accordingly. I have a 1976 Evinrude 15hp. I try to use non-ethanol gas, but if I can’t find it, what type of additive should I use being it’s two-stroke? Thx

I run 87 octane with 10% ethanol in 9.9/15 hp motors. The only addidtive is oil mixed at 50-1

Ok. So the 10% ethanol is ok? I think I ran the same mixture as you just described last year. Didn’t really have an issue. Just wanted to ask for good measure. Thx

If concerned, add some Dry-gas once in a while (methanol based -- burns off water mix).
