i never even read it actually. just pulled the first recent article i could find. but, on the engine damage thing... not sure what you guys run for engines and if they are from the 1980s or something. but, i've never ran anything but the 10% stuff in anything i own, 1979 merc, lawnmowers, weed whackers, all of my vehicles including my 04 dodge with 345K on it. and can't say i have ever had an ethanol related engine problem. considering a person can hardly find ethanol free gas in most of the country and that E10 or better accounts for more than 95% of the gasoline consumed in this country, it can't be as big of a problem as people make it out to be in my non motor head mind.

"WHAT THE OUTBOARD MANUFACTURERS SAY
The bottom line seems to be that modern outboards are fine with fresh ethanol up to E10, but they warn about fuel system risks.
Evinrude: Evinrude motors can tolerate up to 10 per cent alcohol in fuels, (which is the maximum currently sold in Australia)
Honda: Honda engines are designed for good performance and efficient operation using gasoline containing from 0 to 10 per cent ethanol.
Mercury: Mercury engines will withstand up to 10 percent ethanol in gasoline.
Suzuki: Recommends the use of pure gasoline without alcohol, but can use up to 10 per cent alcohol if necessary.
Tohatsu: Recommends use of fuel up to only 10 per cent ethanol. Voids the warranty for all alcohol-fuel related malfunctions.
Yamaha: All 2008 and later models are suitable for use with Ethanol E10 blended fuel. Models prior to 2008 are not suitable for ethanol blended fuels.

it didn't take long for the damage to occur when EtOH first came out
most people shrugged and bought new yard tools, motors, etc.... not realizing they'd been EFF'd by the usual unintended consequences of the gov't "helping"
even if they did know what caused it - who you going to sue to get reimbursed?
