Not Your Typical Two-Stroke

Piston upstroke. Piston downstroke. Two simple strokes that deliver a powerful advantage. Mercury's OptiMax line, the best-selling direct-injection two-stroke outboards on the market, is the culmination of years of technological innovation. If you are looking for superior acceleration and top-end speed while experiencing the clean, quiet, durable and fuel-efficient qualities of a four-stroke -- then OptiMax is the one for you. The results speak for themselves (very quietly).

Designed and engineered to combine the best of both worlds, OptiMax has the heart, soul, speed, and power you expect of a traditional two-stroke. But OptiMax's proprietary two-stage injection system creates a remarkably concise combustion cycle -- giving you the fuel conservation and lower emissions of a four-stroke. A win/win, win/win any way you shake it.


Superior Speed and Performance

OptiMax consistently ranks first among direct-injection engines in holeshot, mid-range acceleration, and top-end speed. That winning consistent performance and unmatched throttle response is due to its Two-Stage Direct Injection System, which provides a constant supply of atomized fuel and air to make the most efficient use of fuel. Additionally, its outstanding power-to-weight ratio results in increased speed and holeshot, making OptiMax a superior engine for any type of boat.


Raw Power, Pure Efficiency

Mercury pioneered direct fuel-injection technology with OptiMax. Ever since, these engines have set the bar to be the industry's low-emission, high-performance leader. But it doesn't end there. OptiMax is so fuel-efficient that it also beats most four-strokes. Thanks to its exclusive two-stage, direct-injection technology, it delivers the ultimate in efficiency, squeezing more miles and performance from every drop of fuel.


The Best Deal Going

OptiMax provides exactly what you need -- from best-in-class fuel economy to unbeatable performance and leading corrosion resistance. The OptiMax lineup's durability, reliability, and advanced direct-injected system make it a spectacular value.
