Ethanol blends of gasoline have a much shorter shelf-life in terms of storage than did the older MTBE formulations. This is due to the ethanol making the gasoline more susceptible to breaking down, especially in a marine environment.
The Ethanol is used as an octane booster, and once ethanol blend gasolines have absorbed enough water from the air, the ethanol will separate out and it will stop working as an octane booster. It also attacks the resin in some of the older built-in fiberglass tanks, and causes huge problems, as the resin residue will gum up the engine and carburetor.
Ethanol also attacks rubber seals, and on older engines, the seals may not be designed to resist this.
One last thing—ethanol blends of gasoline tend to burn hotter, as ethanol is an oxygenator, and this can lead to problems on some engines, as the increased temperatures will cause premature wear and aging.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
