Performance Development of the Supercharged Mercury Marine Outboard Engines

A new family of high specific power 4-stroke outboard engines was developed. This new family of inline, supercharged and charge air cooled engines was targeted to deliver best in class torque curve for superior boat performance.

Program performance targets were met by developing an outboard specific supercharger and charge air cooler, high efficiency gas exchange system, and optimized combustion process while maintaining durability targets.
