In a class all its own.

For people who demand speed and acceleration from their outboards, the OptiMax Pro XS is the only choice. Mercury engineers leveraged the Mercury Racing heritage to develop this family of high-performance Direct Injected outboards. The result is an outboard family that blows away the competition when it comes to power, durability, performance and fuel efficiency.

Nothing on the water today is faster or more proven than the OptiMax Pro XS. And we’re proud to introduce the newest addition to this family, the 150hp OptiMax Pro XS. In head-to-head tests, the 150 Pro XS outran the competition by almost 5 MPH while delivering 15% better fuel economy! The 150 Pro XS is a perfect fit for those anglers looking to increase the performance of their 18-foot fishing boats.

With remarkable acceleration and awesome performance, the Optimax Pro XS lineup has created a class of its own. Nothing else is faster or more proven than the OptiMax Pro XS.

  • 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. Visit the mercurymarine.com Prop Selector to choose the prop that’s right for you.
  • 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.
  • 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.
Fuel Efficiency
  • Ultimate Efficiency: The innovative OptiMax Direct Injected system delivers the ultimate in efficiency, squeezing more miles and performance from every drop of fuel. The unique shapes of the OptiMax-exclusive Dome-Shaped Pistons and combustion chambers enhance fuel economy and lower emissions by efficiently directing the fuel/air charge to the spark plug. The OptiMax Air Compressor provides a steady charge of cooled air for maximum combustion efficiency.
