Some call it a two-stroke. Some call it direct injection. Others simply call it the best-performing outboard on the water. From the rocket hole-shots to the unmatched top end, OptiMax sets the standard for power, acceleration, and fuel economy.
OptiMax engines are some of the most fuel-efficient engines on the water. Two-stage direct injection turns fuel into propulsion fast and efficiently. More distance per drop. More money for crankbaits. More time fishing instead of gassing up. Direct injection strikes again.
From its lightweight design to its outstanding top speed, it’s a reputation built on performance. But there’s a whole lot more to the story. The lightning fast throttle response, the legendary reliability, the fuel savings, the low noise and emissions. OptiMax engine. Another word for everything.
Precise and consistent fuel charge for perfect combustion. More power. Lower emissions. In fact, low enough to meet the toughest, most demanding international air-quality standards. Nothing gets a boat out of the hole, on plane, and across the lake quicker and more efficiently.
Two-stroke power and acceleration, for sure. Fewer moving parts, yes. But a few new things you'll have to get used to. Like less fuel, smoke, and maintenance. More time on the water. We think you'll adjust.
Reliable, versatile, and a great value.

More than a decade of reliable Mercury® OptiMax® performance is testimony to a great design. Low-pressure Direct Fuel Injection (DFI) delivery, corrosion-resistant alloys and finishes, and rugged components keep Mercury OptiMax outboards on the water, season upon season.
Atomized fuel is injected directly into each combustion chamber, backed by a precise charge of compressed air, and the fuel / air mixture is directed toward the spark plug by a uniquely shaped piston. The result is more-complete combustion for outstanding economy and smoke-free emissions.
No outboard in its class weighs less than the Mercury® 250hp OptiMax®. That helps create amazing hole-shot acceleration, increased top speed and overall efficiency. Its compact 60-degree V6 engine delivers brawn without the bulk.
The optional center-mounted Big Tiller offers optimal control. A longer tiller grip incorporates a convenient power trim switch, the shift lever is close at hand, and an optional digital troll control adjusts engine speed as low as 700 rpm in 10-rpm increments.
A 60-amp (756-watt) belt-driven alternator keeps batteries charged to power electronics, lights, livewells and audio equipment.
The Torque Master II gearcase, available on select 225hp and 250hp Pro XS™ outboards, is designed specifically for performance bass boats. 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.
