I had trouble chasing down a problem on my previous boat partly because EVERYONE told me it was related to ethanol. I was pretty sure that wasn't the case, but not smart enough to determine what it was. I went from changing filters once every 4 years to once every two weeks, adding all kinds of additives, and nothing helped. New plugs, new distributor cap & rotor, new coil, new batteries, new battery cables, removed fuel flow transducer, replaced fuel vent, drained entire gas tank, and nothing helped. Finally someone thought it had nothing to do with ethanol and suggested a $10 part. I swapped it out and life was good again.
If you read enough here, people will make it sound like gas that has been sitting in your boat for 14 days is at the absolute end of its life and only a crazy person would use it.
When gas has been sitting for a long time, and by long I am talking a couple of years, it can (and does) go bad. When it does, the smell often turns somewhat foul. Even if it is still recognizable as gas, if it reminds you of feet or a full dumpster in the middle of summer, it's time to get rid of it.
