Whether you're boating for leisure or to make a living, our big-block range delivers the power and performance you demand. Suzuki's DF175 is based on an inline four cylinder DOHC powerhead with a 2,867cm³ (174.9 cu.in.) displacement. While the large displacement contributes greatly to producing exceptional acceleration and torque, it doesn't mean that they are comparatively larger and heavier in size. On the contrary, Suzuki's engineers have targeted this big block motor to be one of the lightest four strokes in the 175 HP class.

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.

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

CONVENIENCES THAT MAKE OPERATING A PLEASURE
Suzuki outboards are designed with features that make your boating experience that much more pleasurable. The DF175 incorporates a high output alternator 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.

TRANSFERRING POWER INTO SPEED
The DF175 is 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.

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.
