Choice of Champions:
OptiMax Pro XS is the best-selling tournament-fishing outboard in the world, and has powered more competitive anglers to victory than any other engine. Run with the same confidence professional tournament anglers have – trust OptiMax Pro XS.
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™ 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.

Fury Prop:
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.
