Mercury Optimax 250 Boat | NMSLight 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.

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.
