A marine propulsion engine is engineered to power ships and boats by transforming fuel into mechanical energy. This energy creates thrust allowing the vessel to move through the water. Through fuel combustion the engine generates power, which is then transferred to the propulsion system effectively driving the vessel forward. Increasing demand for high-performance engines for heavy load transport in association with a strong focus on developing propulsion systems that deliver greater fuel efficiency to lower operating costs and reduce environmental impact will energize the business scenario.
