Most recreational boats in the US are “trailer” boats.  Stored in the backyard or driveway, they are trailered to the water and enjoyed for the day. They are also refueled at your local gas station or minimart, which may soon offer a fuel, E15 (or 15 percent ethanol), that is prohibited by the federal government for use in boat motors and violates engine manufacturer warranties. That has the nation’s largest recreational boat owners group, BoatUS, concerned over the potential for accidental misfueling.

“As this new fuel starts appearing at the local fuel pump, we see the real likelihood of putting the wrong fuel in your boat,” said Margaret Podlich, BoatUS vice president of government affairs. “It could lead to costly engine or fuel system damage, and potentially leave you stranded out on the water with a disabled vessel, compromising your family’s safety. When a boat’s engine stops running, you can’t pull over to the side of the road.”

Earlier this year, the EPA authorized the use of E15 in 2001 model year and newer motor vehicles. However, the agency did not authorize its use in marine engines or off-road vehicles, tools and equipment.

“I encourage anyone fueling – whether it’s for your boat, car, motorcycle, generator or six-gallon portable tank for your lawnmower or leaf-blower, to absolutely know what type of gas is going into that tank,” she said.
