unless you can guarantee you are going to keep your fuel system ethonal free, at this point and time with the treatment options available it seems like a exercise in futility....
I will admit that for small things like chainsaw, lawn mower etc. trying to stay ethanol free maybe worth while, but boats and cars when you using them all the time....

The problem is usually shelf life or switching back and forth.
Ethanol generally has a shorter shelf/storage life without the additives than ethanol free does.
Ethanol will also dissolve the varnish created by the oxidation of regular gasoline (some brands have put a lot of additives in to diminish the varnish build up even without the ethanol).
So if you switch back and forth, you can build varnish... partially dissolve it releasing it into the smaller apertures of your fuel delivery system and cause clogging.
