Boaters beware!! A recent authorization allowing the summer sale of gasoline containing 15% ethanol (E15) at roadside gas stations presents a problem for boaters. This type of fuel is federally prohibited for recreational vessel use, causes marine engine damage, and will void marine engine warranty.
Additionally, E15 fuel has been shown to make engines run hotter, increasing the potential of a catastrophic boat fire. Signs or warning labels may not be obvious at the pump as it may simply be marked as “regular 88” or “regular unleaded”.
The convenience of filling a tow vehicle and boat at the same time may cause boaters to overlook this potentially dangerous detail. Please ensure the fuel you are dispensing into your boat contains no more than 10% ethanol (E10).
