PERFORMANCE

Powerful and Smooth

The OptiMax Two-Stage Direct Injection System produces consistent performance and unmatched throttle response by providing a constant supply of atomized fuel and air. The Pro XS also offers a Higher Wide-Open-Throttle RPM Operating Range, giving you more propeller options to maximize the performance of your boat.

Light and Fast

The compact 60-degree V6 block combines the smooth-running characteristics of a powerful V6 engine with a slim, lightweight design, making it a great choice for almost any type of boat. It consistently outperforms other DI engines in holeshot, mid-range acceleration and top-end speed.

Run with the Pros

The tournament-tested Mercury ProXS lineup is the choice of thousands of performance-minded anglers. Only OptiMax ProXS engines feature durable and responsive Carbon Fiber Reeds to control airflow into the engine crankcase, while dome-Shaped Piston Heads direct the fuel-and-air charge to the spark plug more efficiently. This results in amazing power, outstanding durability, and excellent running quality. In head-to-head tests, the 150hp ProXS outran the competition by almost 5 MPH – while delivering 15% better fuel economy. In addition, we outfitted the 250hp ProXS with Solid Billet Aluminum Mounts to keep the engine from turning or twisting under high torque (20-inch models only).

Reliability

Long-Lasting Stainless

OptiMax is built with more stainless steel and corrosion-resistant components, which translates to saltwater durability, longer intervals between maintenance, and lower cost of ownership. In addition, our lower-pressure direct-injection system also provides superior component durability and longevity.
