Are you a marine engine mechanic? Most of them I know have gotten gray hair dealing with ethanol problems. Some of your statements are not congruent entirely with facts. Ethanol has a known propensity and affinity to absorb moisture and as well there are phase separation issues. With an automobile or high use vehicle this problems are largely avoided but with boats (and my word if it were to be used in an aircraft) where they sit for weeks at a time or longer, ethanol is a KNOWN and FACTUAL problem.
I have had no particular issues with ethanol fuels since I am religious about keeping fresh fuel and pumping remaining fuel out and burning it off in my autos. I also dose with Starton and Techron (which is the major constituent of Mercury Quickleen product) or just run the Quickleen. The formula was changed a few years back and I, without any real evidence to back it up, believe that the older Quickleen is now provided as Quickcare (step 1) and Quickleen (step 2). If I know I have to leave fuel for a few weeks I dose with a marine fuel stabilizer. But, whenever possible, I purchase ethanol free fuel. It costs a small fortune to fill up as it is so if I have to pay extra to get a quality fuel, it is worth it.
There are plenty of ethanol threads on The Hull Truth boating forums with plenty of guys there who actually have experience in the marine boating industry and not just anecdotal here say.
