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	DF175
	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 accelera-
	tion, quick throttle response and exhilarating top-
	end 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 contributes 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.
