maybe there ready for ethanol but the issue is when it sits, still seeing carbs with seized needle seats ect due to ethanol, fuel injection doesn't seem as affected though(guessing more stainless steel components), but i am still fixing a ton of boats and sleds with ethanol related issues, or anything that tends to sit for long periods of time, problem1 is corn alcohol is a solvent and will eat away at rubber, brass and other fuel components over time seen many a leaking omc carb bowl due to it then it absorbs water gets even more acidic and causes corrosion
