Question
What are the negative properties of ethanol?
 
Answer
 
  A. Ethanol has several properties that contribute to fuel system issues.
• Ethanol is a strong cleaner (solvent).
• Ethanol is hygroscopic (e.g., it has a strong attraction to moisture).
• E10 fuel’s usable life span may be less than the normal length of off season boat storage.
