SETTING A NEW BENCHMARK FOR FOUR-STROKE PERFORMANCE
Our engineers took advantage of advances made in four-stroke engine technology and performance in designing the most powerful four-cylinder outboards Suzuki has ever built.

THE LARGE DISPLACEMENT AND LIGHTWEIGHT FOUR-STROKES
Suzuki’s talent for delivering high-end power from compact designs is clearly evident in this pair of in-line four-cylinder outboards. Turning the key unleashes big block performance from their 2,867cm3 powerheads but while their large displacement contributes greatly to producing exceptional acceleration, it doesn’t mean that they are comparatively larger and heavier in size. On the contrary, Suzuki’s engineers have designed these big block motors to be compact and lightweight.

MORE POWER WHERE YOU NEED IT
The DF175 takes full advantage of Suzuki’s advances in four-stroke engine technology to deliver high-end power and performance. A continuously variable valve timing system like the one found in our flagship DF300 delivers powerful mid-range acceleration. And for top-end performance that has to be experienced to be believed, both outboards utilize multi-stage induction, which provides efficient airflow into the engine at the upper end of the power curve.

FUEL EFFICIENT OPERATION THROUGH SUZUKI TECHNOLOGY
The DF175 and DF150 deliver amazing performance but not at the expense of economy. Utilizing a 32-bit onboard computer to optimize electronic fuel injection performance, both outboards offer superior fuel economy, conform to EURO 1 emission standards, and have received a three-star rating from the California Air Resources Board (CARB).

TRANSFERRING POWER INTO SPEED
Both the DF175 and DF150 are designed to swing a larger diameter prop and feature a more aggressive gear ratio. The combination of larger prop and lower gear ratio delivers superior holeshot, which is especially valued on high-performance boats.

CONVENIENCES THAT MAKE OPERATING A PLEASURE
Suzuki outboards are designed with features that make your boating experience that much more pleasurable. The DF175 and DF150 incorporate high output alternators to keep an assortment of electronics up and running, water-cooled voltage regulators with isolators that allow use of two batteries, and a conveniently located fuse box. Also featured are tilt limit switch and two engine flush ports.
