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
consistently leads every DI category—including power,
fuel efficiency, reliability and versatility—it remains the
best value on the water. For performance, power, reliability and value, nothing can compare to the OptiMax.
Boaters have long been drawn to two-strokes for their
raw strength, but traditionally they had lower fuel economy
and poorer running qualities than four-strokes. OptiMax
kept the two-stroke advantages while answering the
four-stroke challenge. The OptiMax

OptiMax ProXS
OptiMax
Born with Racing in its Blood Tournament com-
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.

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.

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 finest 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.

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.

RELIABILITY
Can more than a decade of satisfied
customers be wrong?
Proven, Time and Again
OptiMax outboards have earned the
trust of more customers than any
other DI outboard because of the
painstaking attention Mercury
engineers pay to every minute detail.
Of all Mercury’s countless marine innovations, the OptiMax outboard, year after
year, has stood out as its most proven engine technology. Since it was first introduced more than a decade ago, OptiMax has reeled in numerous leading awards
for customer satisfaction. OptiMax has earned recognition as the two-stroke industry leader thanks in large part to its lower-pressure DI system and reliable stainless
steel components that lend to its superior longevity and durability. It’s no wonder
OptiMax is consistently the best-selling DI outboard on the market.
Maximum Performance
With optional SmartCraft® integrated marine technology, the advantage of running
an OptiMax engine hits new levels. 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.
