More information on ethanol E10 fuel use in marine engines:
Avoid using any marine fuel system treatment product that contains alcohol or strong solvents with E10 gasoline.
Because boat fuel systems are constantly being challenged to prevent water absorption into the fuel system, numerous "Gas Treatment Products" marketed to the marine industry ALSO contain alcohol. (Becuase alcohol has such amazing hygroscopic water-absorbing and cleansing capabilities.)
Fuel System "Cleansers", "Rust Removers", "Octane Boosters" and more, are often alcohol-based products.
Marine engines require intense lubrication and prevention of rust. Most oil-based marine lubricants do not contain alcohol -
Lubricants and fuel conditioners (that do not contain alcohol or butanes) can offer extra support when using ethanol blend fuels.
Ethanol alcohol present in E10 fuel, is a drying agent - Lubricants, conditioners and greasers counteract some of the negative effects of alcohol and help to prevent drying out and cracking of boat engine parts and hoses.
-------------------------------------------------
Most major marine engine manufacturers warn against use of ethanol alcohol blends of fuel.
-------------------------------------------------
Several states, still do not require the gas stations are to disclose that ethanol was added to the gas pump!
---------------------------------------------------
Using gas with over 10% alcohol will damage most engines and cause major engine performance problems.
E10, which contains levels of 10% or lower alcohol, is safe for most engines -But ethanol can accidentally be blended into the gas at the pump at dangerously high levels.
Protect your engine by checking alcohol presence and content with a portable Ethanol Fuel Test Kit and/or Quik-Check indicator solution.
--------------------------------------------------
Due to ethanol's affinity for water, phase separation and water contamination occurs quickly.
The shelf life for ethanol blend fuel is only 90-100 days under ideal, low humidity conditions. Compared to conventional gasoline, ethanol blend fuels can absorb up to 50 times more water.
--------------------------------------------------
Use caution when removing water/ethanol lower layer from gas tank. Ethanol is an octane-enhancer, and removing it from E10 gas will drop octane rating - Running a marine engine on low octane fuel causes engine damage and performance issues.

Ethanol Fuel - What are the dangers?
Simply put, ethanol is an excellent SOLVENT, CLEANSER, DRYING AGENT and unlike MTBE, ethanol gas will ABSORB WATER. Ethanol easily and quickly dissolves resins, rust, dirt etc. that creates a sludge that coats and travels through the engine, causing engine stalling and complications, including clogged fuel filters, carburetor jets and injectors.
The following information is a guideline only, effects from alcohol fuels will vary. Always follow equipment's fuel recommendations and review your owner's manual and warranty statements for fuel requirements.
