Suzuki's DF150AP incorporates the Drive by Wire Suzuki Precision Control System for easy, smooth and precise throttle and shift operation. The AP model also incorporates Suzuki Selective Rotation which enables the outboard to operate in either clockwise standard rotation or counter clockwise rotation. The DF150AP 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 most versatile four strokes in the 150 HP class.
