That's why I'm curious about marine applications. If the tank is sealed (minus a vent or two), then how else would moisture accumulate? I would think if you ran the tank low pretty frequently, one would be OK. I'm just looking for an alternate high octane solution for him that doesn't involve $8.00/gal fuel or a degree in chemistry to mix up. Not to mention, it's just different, and I like that.
I guess you could say it's a "pleasure boat'', in that, it brings him pleasure. To be specific, it's an Allison XB-2003 (bass/sport/drag) boat. Used for fishing, but also going 100+ in a relatively short amount of time. Also has a nitrous/alcohol injection setup w/ it's own dedicated fuel system/injectors. Any idea how corn plays with the 'other' alcohol?
