As the world leader in marine propulsion technology, Mercury acknowledges its responsibility to produce Earth-friendly engines. No company is more devoted to developing and perfecting clean marine power than Mercury.

Mercury sells more four-stroke marine engines than anyone else, and our FourStroke technology exceeds EPA emissions standards. In addition, all Mercury FourStroke and two-stroke Direct-Injected outboards, including Mercury Verado® and OptiMax® engines, are certified by the California Air Resources Board (CARB).

Our quest for clean, efficient power is a neverending process. We constantly seek improved methods to squeeze maximum performance from every drop of fuel, yet leave minimal or no trace in the environment. We value the Earth, its environment and natural resources, and we're committed to treating both with respect.
