Keeping it clean for the future.

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

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

Our quest for clean, efficient power is a never-ending 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.
