Accidentally misfueling a boat with E15 fuel can lead to expensive repairs.

The nation’s largest advocacy, services and safety group for recreational boaters, Boat Owners Association of The United States (BoatUS), reacted negatively to the recent news of the Administration’s plan to permit the sale of E15 (15 percent ethanol) fuel year-round.

E15 is prohibited by federal law for use in recreational boat engines, voids many marine engine warranties, and is currently banned for sale in many states by the Environmental Protection Agency (EPA) during summer months over concerns that it contributes to smog on hot days. Under the Administration’s new proposal, however, the Environmental Protection Agency (EPA) would grant a waiver to the Clean Air Act to permit the sale of E15 in all 50 states year-round at the same roadside gas stations where most recreational boaters refuel their trailered vessels.

The BoatUS statement said today:

“The proposal to permit the sale of a fuel (E15) during the peak summer boating season that is both harmful and illegal to use in marine engines is a major concern for boat owners. The nation’s 11 million recreational boaters want fuel that is safe for their boats, however, this proposed EPA policy change will increase the chances that boaters could inadvertently put engine-killing E15 into their tanks. Unlike the physical barriers that prevent misfueling between gasoline and diesel fuel-powered vessels, just one small orange warning label on the fuel pump is all that stands between a boat owner making a misfueling mistake that could lead to expensive, warranty-voiding repairs and catastrophic engine failure.”
