Powerful and Efficient.
An OptiMax 250hp Pro XS gets up to 14% better fuel economy than a 250hp four-stroke offered by our competitor. Our direct-fuel-injection system boasts the most complete fuel and air atomization, while specialized pistons improve fuel combustion. More power. Less fuel consumed. Fewer emissions produced. Perfect.
Geared to Win.
The Torque Master II gearcase, available on select OptiMax® 225hp and 250hp Pro XS&trend outboards, is designed specifically for performance bass boats with top speeds of up to 85 mph. Its stout 1.25-inch prop shaft can handle the strain of running at an elevated mounting height. Patented front water pickups keep the engine running cool regardless of engine height. A cambered skeg improves handling and drivability.
Speed / Performance.
Carbon Fiber Reeds increase power and torque for spectacular acceleration and top speed, while custom exhaust tuners and high-performance cylinder heads maximize power and overall performance.
Quick and fast, the Fury® propeller from Mercury improves hole shot on tournament bass rigs by 12% and top speed by 1.4 mph compared to the Mercury Tempest® Plus propeller. Fury is an ideal match for outboards 200hp and up.

- 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).
- 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.
