Strong, quiet and easy to transport, Mercury®
FourStroke Portables are anything but lightweight
when it comes to performance. Available in 2.5 to
25 horsepower, these FourStrokes incorporate
the lessons we’ve learned in more than 65 years
of perfecting outboard technology for the marine
environment.
In short, we took championship-winning power
and performance and made it everything a
four-stroke should be:
Clean and Quiet Reliable
Fuel-Efficient No Mixing of Gas and Oil
Additionally, most manual-start FourStroke
Portables feature a camshaft decompression
system that makes them easier to start than
competitive four-strokes.
™
Fast, reliable outboard power – you really can
take it with you no matter where your boating
adventures lead. With Mercury Portables you get
the dependable power and performance you need
without sacrificing convenience. With horsepower
ranging from 2.5 to 25, Mercury Portables are
made to fit in the back of your car as easily as
they fit on the back of your boat.
All models offer quick, easy starts and a rubber-
insulated transom mounting system to reduce
vibration and driver fatigue. And many feature
simple, one-handed operation with shift, throttle,
steering, throttle friction, and stop controls all
designed to fit in the palm of your hand.
After all, boating is supposed to be fun and easy.
Tough, dependable Mercury Portables help you
keep it that way.
™
• Easy one-handed operation.
• Through-prop exhaust on most
models buries engine noise
underwater for a quieter, more
enjoyable experience.
• Multiple trim positions
(including shallow-water
drives on select models)
provide optimum performance.
• Standard water-separating
fuel filter to minimize debris
and water in the engine on
select models.
• Lanyard stop switch
for added safety.

BIG PERFORMANCE IN
A SMALLER OUTBOARD
THREE-YEAR
WARRANTY
Every Mercury FourStroke is
backed by a limited three-year
factory warranty.
CLEANEST
BY FAR
All Mercury FourStrokes (except 15 hp)
exceed the EPA emissions standards for
2008 and have received a CARB three-
star ultra-low emissions rating. They’re
all clean and efficient but boast plenty
of torque to keep it fun.
Versatile, reliable and fuel-efficient Mercury Portables run laps around the competition.
Literally. Available with horsepower ranging from 2.5 to 25, these high-performance
powerhouses are designed to work harder than the average outboard.
Take our BigFoot Portables for example. With their oversized gear cases, larger props and
greater gear reduction, BigFoot Portables are engineered to provide greater thrust,
maneuverability and holding and stopping power. Their portable design makes them ideal
for use on pontoons, light-duty commercial craft and inflatables, or as auxiliary power on
sailing or fishing boats.
From the convenient tiller-handle controls to a beefed up transom assembly, the 9.9hp
ProKicker is fisherman's dream. Built to handle the meanest whitecaps and get to the fish
quicker, the Pro Kicker features a superfast power tilt, centering straps that keep the
engine aligned while under main power and a four-blade, high thrust propeller for superior
handling and ultra-slow trolling speeds.
Add in the fact that Portable FourStrokes can run off your main fuel source, and it’s no
wonder more and more fisherman and pro anglers are making our FourStroke Portables
their kickers of choice.
THREE-YEAR
CORROSION WARRANTY
Every Mercury engine is
backed by the industry’s only
three-year corrosion failure
limited warranty, further
proving that we stand behind
our power.
