Changing the Two-Stroke GameHow do you compare something that is incomparable?More than a decade ago, Mercury introduced the directinjected OptiMax engine, and the game was changed—old comparisons suddenly meant nothing. Blending thebrawn of a two-stroke with the efficiencies of a four-stroke, OptiMax has since become the most preferredtwo-stroke direct-injected outboard on the planet.

Boaters have long been drawn to two-strokes for theirraw strength, but traditionally they had lower fuel economyand poorer running qualities than four-strokes. OptiMaxkept the two-stroke advantages while answering thefour-stroke challenge. The OptiMaxdifference begins with a simple focus: air. A burst of pressurized air shoots the

fuel into the cylinder and optimizes fuel atomization—the smaller the fuel particle, the better the combustion—fora more consistent and complete burn.

The result is better fuel efficiency and smoother, smoke-free performance from a two-stroke that still deliversblistering acceleration, incredible throttle response and asuperb power-to-weight ratio. And though OptiMaxconsistently leads every DI category—including power,fuel efficiency, reliability and versatility—it remains thebest value on the water. For performance, power, relia-bility and value, nothing can compare to the OptiMax.

Fastest, most proven, designed to fly... the most preferred two-stroke on the planet.

OptiMax

Unsinkable Value For the value-conscious boaterwho’s still looking to amp up his outboard performance,nothing compares to the power, fuel efficiency and reliability of OptiMax. OptiMax outboards run faster,cruise farther and cost less to operate than competingmodels. With its unique two-stage fuel injection system,OptiMax achieves remarkable mpg and top speed in atrustworthy package that has consistently earned thepraise from thousands of satisfied anglers fishing in theroughest real-world conditions. There is nothing theo-retical about the OptiMax advantage. It has proven itsreliability and value for more than a decade.

OptiMax ProXS

Born with Racing in its Blood Tournament com-petitors know that their spot on the leaderboard dependson getting to hot spots as quickly as possible. And nooutboard has won more tournaments than the MercuryProXS outboard. Inspired by the legacy of MercuryRacing®, the OptiMax ProXS engine was developedto be faster, stronger and flat-out better than the rest.And with thousands of weekend and competitive anglersdepending on the OptiMax ProXS, you can feel confi-dent that nothing else compares to its power and reliability.

Mercury does more than make industry-leading outboard engines. Offering a variety of parts and accessories designed to improve the performance, ride and efficiency of your OptiMax engine, Mercury is dedicated to elevating your boating experience to its highest potential.

Prop ProsNobody knows propellers like Mercury does. Formore than 60 years, Mercury has been designingand building the best marine engines and driveson the planet. That experience and expertise hasled to proprietary technology breakthroughs suchas the performance-boosting Flo Torq prop sys-tem; X7 Alloy, which is 30 percent stronger thanconventional stainless steel; and the PerformanceVent System, which allows you to adjust vent

plugs based on load and environment for opti-mum acceleration. All three of these innovations(among others) are found on Mercury’s state-of-the-art Fury tournament bass propeller. The Fury,Mercury’s most sophisticated bass prop, measura-bly improves bass boat acceleration and topspeed—to the tune of 12 percent faster holeshotand a top-speed boost of 1.4 mph. The Fury is anideal match for 200 hp outboards and up.

Mercury OptiMax Outboard OilWhen it comes to taking care of your OptiMaxoutboard, look no further than Mercury OptiMaxOutboard Oil—the recommended oil from the peo-ple who designed and built your OptiMax outboard.

The specially formatted DFI oil is designed to providemaximum protection across a wide range of operating

conditions such as long periods of running at wide-open throttle, or extended time at idle. It also offersoutstanding protection against carbon build-up,which helps your OptiMax deliver the top speedand acceleration you count on. Mercury OptiMaxoil is a must-have for boaters who want to ensurethe performance and life of their engine.

Mercury Fuel Care SystemMercury’s specially formulated 1-2-3 fuel care system is designed to keep your engine hummingsmoothly and optimize performance, whether youuse ethanol-blended or non-ethanol-blended fuel.Step one, Quickare fuel treatment, maximizes performance by controlling moisture, corrosionand buildup (and phase separation with ethanol-blended fuel). Quickare cleans up existingdeposits and keeps fuel fresh between fill-ups.Step two is Quickleen engine and fuel system

cleaner, which aggressively removes carbon depositsfrom carburetors and injectors, intake valves, sparkplugs, piston crowns and cylinder heads. It extendsspark plug life and prevents engine knocking andpiston seize-up. The final step, Quickstor fuel sta-bilizer, prevents fuel breakdown and oxidation,combats corrosion and the formation of gum andvarnish in your system, keeps injectors and carbu-retors lubricated and stabilizes fuel for up to a year.
