There is nothing requiring a 10% ethanol content in marine gasoline. In fact, Channel Marine sells Valvtec marine gasoline, which has no ethanol.

Non-ethanol gasolines tend to cost a little more. This is because ethanol boosts octane rating, and without ethanol that boost is gone. Therefore the gasoline has to have more octane or octane equivalent to bring the rating up.
