SUZUKI 4-STROKE PORTABLES. EASY TO CARRY. EASY TO USE.
SUZUKI DF4| DF6 PORTABLES
Suzuki designed the DF4
and DF6 to be compact
and lightweight with added
features that make their
operation more user-friendly.
The DF4 and DF6 are
4-strokes so you can expect
clean, economical operation,
and like all Suzukis, they
deliver excellent power,
performance and durability.
USER-FRIENDLY FEATURES
Tiller Handle
The DF4 and DF6 are equipped with a
tiller handle that extends out from the
steering bracket. This design positions
the operator further forward in the
boat to provide better weight distri-
bution which, helps in getting an
inflatable to plane quicker.
The outboard is
designed to turn
90° both left and
right of center.
This feature
helps docking
and tight turning
of the boat while
its 90° stopping
points provide
an easy-to-
recognize refer-
ence of the outboard’s angle.
With the tiller handle attached to the
steering bracket rather than the motor
itself, and the utilization of a large
rubber mount inside the same steering
bracket, vibration in the tiller handle
has been greatly reduced. Steering is
smoother due to the utilization of an
upper bushing placed between the
steering bracket and the swivel brack-
et. Steering tension can be adjusted
with a large friction adjuster to
regulate steering effort and feel.
Carrying Handle
Carrying the out-
board is made easier
with the incorpora-
tion of a large, ring-
shaped carrying
handle. Designed
with smooth edges
and lacking any
sharp angles, the carrying handle
offers plenty of space for both hands
and is positioned to balance the load.
Tilt Up Handle
A handle built
into the backside
of the engine
cover offers easy
tilting of the out-
board. Lifting on
the handle
makes tilting of
the engine from
the normal drive
position to any one of the two shallow
water drive positions or full tilt posi-
tion a simple operation.
Providing
Power
Both the DF4
and DF6 utilize
an OHV single
cylinder 4-stroke
engine. With a
138cc displace-
ment they offer
the largest
displacement
found in this
class of out-
boards but
compact and efficient designs have
kept their weight to a minimum.
Producing excellent low- to mid-range
torque, these engines, in combination
with their light weight, deliver excel-
lent acceleration.
Also, 4-stroke operation provides
the DF4 and DF6 with greater fuel-
efficient operation, less vibration and
quiet operation while eliminating the
need for mixing oil with the fuel. This
keeps your boating experience clean,
pleasant and user-friendly.
MORE FEATURES THAT
ASSIST IN OPERATION
Large Clutch Lever
Both outboards are fitted with
a large plastic clutch lever that
promotes easier shifting.
Digital CDI with Ignition Coil
The DF4 and DF6
are the first out-
boards in the
world to utilize a Digital
CDI ignition system
equipped with an ignition
coil. The single unit
system is compact, lightweight
and highly resistant to
corrosion. It also acts as
an over-rev limiter while
providing stable idling.
Optional Alternator
An optional 12V 6A alter-
nator is the largest alternator offered
in this class. This system is designed
to provide charging power from as
low as 2,200 rpm.
Integral Fuel Tank
Both the DF4 and DF6 are equipped
with a built-in 1.5-liter fuel tank that
is the largest fuel tank offered in their
class. Using a 12 ft. aluminum boat
in a factory test, the outboard ran for
a total of 45 min (approximately 2.0-
liter/hour) on a full tank of fuel. This
makes short excursions possible
without the use of an external fuel
tank. For extended use, the DF6 is
equipped with
a remote fuel
connector for
use with an
external tank
(optionally
available on
the DF4).
Pilot Water
Hole and
Fresh Water
Flushing
System
The pilot water
hole is located upstream of the
cylinder to confirm that there is water
circulating soon after the motor is
started. The pilot water inspection
tube is removable to permit cleaning
of the tube and the attachment of an
optional connector allows freshwater
flushing of the cooling system.
