Suzuki DF150, DF17 User Manual
Fresh Ideas, Advanced Technology and Innovative
Design Keep Suzuki Ahead of the Competition
Unrivaled expertise, world-class technology, innovative ideas and design… That’s an
excellent summary of what you can find in Suzuki’s line of four-stroke outboards, and
the new DF150 and DF175. At Suzuki, our goal has always been to provide boaters
with the power to get the most enjoyment from their
boating experience. To that end, we have
employed outside-the-box thinking, cutting
edge technology, and refined designs to
develop a line of four-stroke outboard
motors unmatched by the competition.
In so doing, Suzuki built the first fourstroke outboard with digital electronic
fuel injection; created the first fourstroke outboard with a self-adjusting
and maintenance-free timing chain;
developed the first use of an offset
drive shaft with two-stage mixed cam
drive; and designed and built the world’s
first 250 horsepower V6 four-stroke
outboards.
Our commitment to new and better
ideas has earned us the respect of the
industry and acclaim from satisfied
customers. As proof, Suzuki has been
awarded four NMMA awards for outboard
innovation, not to mention the three “Editors
Choice” awards from Motorboating Magazine.
Now we are building on this heritage. Our new
DF150 and DF175 four-stroke outboards are the
most powerful four-cylinder outboards we have
ever built. These new -compact and lightweight
outboard motors provide the benefits of fuel
efficiency and low emissions. More importantly, they
expand on the potential of four-stroke power for
marine applications by delivering powerful acceleration, quick throttle response and exhilarating topend speed.

Big Block – High Performance Engine
Suzuki’s DF150 and DF175 are based
on an all-new inline four-cylinder DOHC
powerhead with a 2,867cm3 (174.9 cu.in.)
displacement—the largest to date in the
four-stroke, four-cylinder category.
While the added displacement contrib-
utes greatly to exceptional acceleration
and velocity, it doesn’t mean that these
engines are comparatively larger and
heavier in size. To the contrary, Suzuki’s
engineers have targeted these big block
motors to be the lightest four-strokes of
their kind.
Taking advantage of advances Suzuki
engineers have made in four-stroke
engine performance, the DF175 utilizes a
continuously variable valve timing system
much like that found in our flagship
DF250. Both the DF150 and DF175
share other advanced features including
multi-stage induction and a 32-bit
onboard computer that monitors and
controls engine functions. Both outboards
have also gained the CARB Three-Star
rating, which identifies engines that meet
the California Air Resources Board’s
2008 exhaust emissions standards.
