5.3.1 Selecting fuel type
Your engine(s) are designed to operate safely on fuel with a maximum of 10% ethanol.
Ethanol in
gasoline attracts water and can absorb moisture from the atmosphere
or marine environment through the fuel tank vent system. In time,
it may cause fuel phase separation. Ethanol attaches itself to water
molecules and drops to the bottom of fuel tank. If the ethanol/water
phase reaches the fuel inlet, it can be drawn into the engine and
cause poor performance or even damage.
