Note there is a typo in the first paragraph. It should say 2007 rather than 2001.

• Compatibility questions: Many components on a boat come in contact with ethanol-laden gasoline, including fuel lines, fuel tanks, fuel pumps, fuel injectors, carburetors, pressure regulators, valves, o-rings, and gaskets. The compatibility of these components with any blend greater than E10 is currently unknown. The failure of only one of these components in your engine could lead to failure or, worse, a fire or explosion.
