These new outboards take full advantage of Suzuki’s proven Ultimate 4-stroke technology to provide season after season of reliable performance. Featuring an off-set driveshaft to move more weight forward on the transom and a 2-stage gear reduction resulting in more torque and less vibration. Largest in-class gear ratio and 2867 cu-in in displacement. Lean-Burn technology provides significant improvement in fuel economy in all speed ranges especially at cruising speed.



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 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.


With a combination of our Lean Burn technology, a semi-direct intake system and a high performance compression ratio of 10.2-to-1, these new outboards deliver clean, efficient power. Compared to the current 175 and 150, the DF175A is 14% more fuel efficient and the DF150A shows a 7% improvement for significant savings at the fuel dock.


With more torque (3.1% more for the DF150A and 2.7% more for the DF175A), as well as Suzuki’s proven offset driveshaft layout with 2-stage gear reduction, these new outboards generate more power throughout the full rpm range. Even on heavier, fully loaded boats, the DF150A and 175A take performance to the next level.


The DF150A and DF175A now share the same engine block used for our popular DF200A. More displacement and improved mechanical design combine for quicker acceleration, whether out of the hole or in mid-range. We’re satisfying our customers’ desire for performance and improved fuel economy.


These new outboards take full advantage of Suzuki’s proven Ultimate 4-stroke technology to provide season after season of reliable performance. A knock sensor keeps the engine running smoothly for improved durability. An O2 sensor improves engine efficiency and Suzuki’s water detecting system helps protect the engine from the effects of bad gas, which include poor combustion, lower power output and corrosion.

  • Data used in this product information was obtained through in-house testing under uniform conditions. Results will vary depending upon operating conditions.




The engine powerhead is offset closer to the transom, moving the outboard’s center of gravity forward.


  • Less vibration

  • More compact engine

  • Stable steering performance



Designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.


  • Protects engine from poor combustion, lower power output, and corrosion.
