Gary, would this aluminum corrosion look like white-ish crystally plaque? that is what I had in my carbs, (3 of six) on a set of twin 40 Yami's. I have been using Stabil, but not the new Marine version, and have been buying automotive fuel (E-10). And it didn't take me 15 min to clean those Carbs  but after the mechanics were through the pair purred like a couple of kittens. Me and the wife however, ate beans and rice for the next month

Yup, that is exactly what it looks like.

Pete-
Great source!
I would particularly like to recommend that everyone read this addition to the report you listed:
Ethanol Fuel Use in Marine - Boat - Outboard Engines
because it deals directly with the use of ethyl alcohol in outbards, the central topic of this discussion!

I'm beginning to think that in boats using E-10, E-20, or E-85, one should once a year take a siphon hose down the fuel intake hose (or remove it at the top of the tank if necessary) and siphon out the bottom inch or two of the fuel mixture to remove any phase-separated fuel, water, or any other crud to keep it from cycling through the fuel intake system towards the motor.
Too bad there's not a drain fitting on the bottom of the gas tank like a radiator or a compressor tank.
Same idea might just apply to infrequently used cars, trucks, and motorhomes.

Joe,
On my tanks (2002- 22 cruiser) the pickup tube was right on the bottom of the tank and would pick up the crud fuel first. I am in the process of installing new fuel tanks since one of my old ones cracked. On the new tanks I can't tell where the fuel pick-up tubes terminate-but I would guess that it would be very near the bottom to avoid too much unusable fuel. I do intend to make the tanks easily removable so that I can totally empty them and clean them out every couple of years.
