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

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

The result is better fuel efficiency and smoother, smokefree performance from a two-stroke that still delivers blistering acceleration, incredible throttle response and a superb power-to-weight ratio. And though OptiMax Boaters have long been drawn to two-strokes for their consistently leads every DI category—including power, raw strength, but traditionally they had lower fuel economy fuel efficiency, reliability and versatility—it remains the and poorer running qualities than four-strokes.

Unsinkable Value For the value-conscious boater

petitors know that their spot on the leaderboard depends on getting to hot spots as quickly as possible. And no outboard has won more tournaments than the Mercury ProXS outboard. Inspired by the legacy of Mercury Racing®, the OptiMax ProXS engine was developed to be faster, stronger and flat-out better than the rest. And with thousands of weekend and competitive anglers depending on the OptiMax ProXS, you can feel confident that nothing else compares to its power and reliability.

who’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 competing models. With its unique two-stage fuel injection system, OptiMax achieves remarkable mpg and top speed in a trustworthy package that has consistently earned the praise from thousands of satisfied anglers fishing in the roughest real-world conditions. There is nothing theoretical about the OptiMax advantage. It has proven its reliability and value for more than a decade.

The Fastest, Most Proven There’s a reason thousands of bass anglers from both the FLW and B.A.S.S. tours prefer OptiMax Pro XS outboards: Test after test has shown that it is simply the best. In a head-tohead speed trial, a 250 hp OptiMax ProXS ran faster and got on plane quicker than an Evinrude 250 hp E-TEC HO. When it comes to serious tournament bass fishing, half the battle is beating the competition to the hot spots—not to mention having the confidence to stay out as long as possible before racing back for weigh-in. For speed and acceleration like that, there’s simply no other engine that can match the OptiMax ProXS. 4


Mercury 250 hp ProXS

Yamaha 250 hp SHO

First to the Fish In head-to-head tests, a Mercury 250 hp ProXS consistently outruns a Yamaha 250 hp SHO at top speed. This means you’ll get to the fish first, where more casts can make all the difference.

A Mercury 250 hp ProXS has up to 14% better fuel economy than a 250 hp Yamaha SHO.

Designed to Fly The jaw-dropping speed of the OptiMax ProXS outboard begins with its two-stage direct injection system, which makes it the quickest, most responsive DI engine in existence. High performance carbon fiber reeds control the airflow into the engine crankcase for improved response and performance. And a higher wide-open-throttle rpmmeans that blistering acceleration carries all the way through to a startling top speed. It won’t be just your jaw that drops.

Confidence that Never Runs Out Just as important as beating the rest of the pack to the prized fishing hole is being able to run farther and stay out longer without worrying about your fuel level. The DI system of OptiMax ProXS boasts the industry’s most complete fuel-and-air atomization, with exclusive domeshaped pistons that more efficiently direct the fuel-air charge to the spark plug. The result: When a competitor sits at the fuel dock refilling, you’re still on the water with miles left in the tank of your OptiMax ProXS. Sources for research and claims on page 16.

The engine choice for the pros—and the tournaments they fish in


Hail to the Victor No other outboard can claim as many victories in professional bass fishing tournaments as the OptiMax ProXS outboard. Inspired by Mercury Racing’s® legacy of developing the highest performing outboard product available, it’s earned its reputation as the most reliable and highest performing direct injection (DI) outboard for the professional fishing circuit. Additionally, the ProXS family of outboards is available with the rock-solid Torque Master gearcase, designed to deliver optimal handling and maneuverability at high speeds.

Tournament Tested, Tournament Approved Thousands of bass pros turn to OptiMax ProXS to get the job done, and both the FLW and B.A.S.S. tournament series have made it the official engine sponsor of their circuits. It’s a testament to Mercury’s standing as the #1 most-trusted name on the water as much as it is a rousing endorsement of OptiMax, the best-selling outboard on the planet. The tournament pros put their trust in OptiMax ProXS, and the tournaments they fish in proudly put their names alongside it. What more needs to be said?

EXPERTISE

Designed by the industry's ďŹ nest engineers, Mercury gearcases help maximize OptiMax performance


Geared Up The OptiMax ProXS outboard certainly delivers incredible power and acceleration, but the story doesn’t end there. Look beneath the water to see more of why the ProXS is the preferred outboard of thousands of anglers. No other marine company has more expertise with gearcase design and hydrodynamics than Mercury Marine. And Mercury uses this knowledge to design gearcases that improve the performance and reliability of your Mercury outboard. The Mercury gearcase advantage includes: Reduced drag Less drag means better boat performance. Patented dual water intakes This Mercury innovation incorporates strut pick-ups and front-mounted intakes to ensure a steady supply of cooling water with any engine angle regardless of the engine’s mounting height. Flat design The pointed gearcases of competitors can often snag weeds, which restrict the intake of critical cooling water. The flat design of Mercury gearcases eliminates this issue.

Mercury’s OptiMax ProXS outboard produces more torque than comparable engines from other manufacturers, throughout the power curve.

Torque Master Gearcase Serious anglers who power their bass boats with OptiMax ProXS outboards will appreciate the unique design of the Torque Master gearcase, built specifically for boats with heavier loads and top speeds between 75 and 85 mph. A larger 1.25” propshaft adds durability when running at elevated engine heights, with patented front-water pickups ensuring optimal cooling no matter your engine height. A cambered skeg improves handling and drivability, meaning you are delivering power through one of the most hydrodynamically efficient lower units available. 9


OptiMax Value — Save and Go Proven value. That’s what OptiMax outboards deliver, and what they’ve been delivering for more than a decade. Why? Because OptiMax’s direct injection technology offers clear advantages, repeatedly leading every DI category, including power, fuel efficiency, reliability and versatility— but OptiMax makes perhaps its most significant impact on your wallet. For starters, OptiMax is the featured outboard offered by hundreds of boat builders as a means to keep boat packages affordable, while delivering the performance boaters demand. Then there are the gains at the pump: Over five years you can save up to $2,710 in fuel costs running a Mercury 200 hp OptiMax instead of a competitor’s DI two-stroke. The 200 hp OptiMax also gets 32 percent better mpg and 49 more miles of range at cruise than its Evinrude counterpart.


The OptiMax Advantage The difference is the proven direct injected system, which boasts the industry’s most efficient fuel-and-air atomization. Unique pistons help redirect the fuelair charge to the spark plug, and the OptiMax air compressor delivers a precise charge of air for maximum combustion efficiency. Every drop of fuel is burned more consistently and completely, allowing you to get the most out of every gallon. And regardless of conditions, your SmartCraft power control module manages the engine to ensure efficiency and peak performance.

Lean and Mean These days, the business mantra is “do more with less.” OptiMax has been accomplishing this since the beginning. The Mercury 225 hp OptiMax is the lightest two-stroke in its class. That’s the “less.” The “more” is significant: Beyond best-in-class fuel efficiency, Mercury OptiMax outboards boast outstanding power-to-weight ratios and acceleration. A compact 60-degree V6 engine block provides the burst without the bulk, allowing OptiMax to strike a sophisticated balance of power and weight while delivering optimal performance.

497LB

518LB

The Mercury 225 hp OptiMax is 21 pounds lighter than the Evinrude 225 hp E-TEC and a whopping 65 pounds lighter than a Yamaha 225 hp offshore four-stroke.

Pays You Back Some engines spend as much time in the shop as they do strapped to a boat. Not OptiMax. A major part of its value comes from its rugged durability. Built with saltwater-tough, stainless steel components, OptiMax is the industry leader in corrosion resistance, adding value by saving you time and money that you might otherwise spend on repairs.

SmartCraft® integrates your boat and engine functions into an intuitive management system. Features such as Engine Guardian, a proactive operator-warning and engine-protection system that alerts you to unusual activity, help you achieve optimal performance from your engine and provide peace of mind while you’re out on the water.

Sum of the Parts OptiMax has earned the trust of more customers than any other DI outboard because of the painstaking attention Mercury engineers pay to every minute detail. From the slim, smooth-running, compact V6 block, to the efficient piston design, every component of an OptiMax maximizes the performance of the whole. The 60amp, 756-watt automotive-style alternator controls electrical output to easily power all your boat’s electronics. Mercury-designed gearcases showcase the best in modern hydrodynamics and are built to deliver precise control and handling. From prop to piston, there’s not a better-made DI engine out there than OptiMax.

Walking the Talk Listing the benefits of an OptiMax engine is not just lip service: Mercury backs every OptiMax with a three-year limited factory-backed, nondeclining warranty, along with the industry’s only three-year limited corrosion failure warranty (excluding Mercury Racing® Outboards). The best DI outboard on the market deserves a warranty to match.
