EPA Region 2 has entered into voluntary agreements with state governments, industry associations, and retailers in New York and New Jersey to promote the sale of clean marine outboard engines. These engines emit 75 percent less air pollution, burn 35 to 50 percent less fuel, use up to 50 percent less oil, and discharge significantly less gasoline directly into the water than conventional engines. The New York and New Jersey initiatives come on the heels of successful EPA agreements with the marine industry and state governments in New England.

New rules for Diesel Boats and Ships
