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 it is 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 DF175 is designed to swing a larger diameter prop and features 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. The DF175 delivers amazing performance but not at the expense of economy. Utilizing a 32-bit onboard computer to optimize electronic fuel injection performance, it offers superior fuel economy, and has received a three-star rating from the California Air Resources Board (CARB).
