Choice of Champions.

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.

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.

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.

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.

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.
