If you're running heavy, run fast.
The DF300B / Four-Stroke Outboard.

Giving props where props are due.
The increased power of this engine requires more powerful gears, and more powerful gears take up more space. How do you design a solution that doesn't compromise performance? Enter our contra-rotating dual propeller system. The contra-rotating propeller provides more "grip" underwater, and because contra-rotating propellers distribute the engine torque evenly over two propellers, the torque per propeller decreases and we can reduce the gear size and design a smaller, more hydrodynamic gear case.

Onboard with offset drive shafts.
By positioning the crankshaft in front of the drive shaft, we've moved the outboard's center of gravity forward, making the outboard more compact and increasing its performance. This design also significantly reduces vibration by moving the engine's axis of inertia-the point where engine vibrations are at a minimum-up over the upper engine mount.

Control you can trust.
Our technologically advanced Precision Control System is a computer-based drive-by-wire control system that eliminates the friction and resistance of mechanical control cables. Operation is smooth and precise with crisp, immediate shifting that is most evident in the low rpm range, when maneuvering around the marina and in close quarters.

Knock it out of the park.
The knock sensor monitors combustion to provide you with optimized performance. In addition to maximizing power output, the system also helps increase engine durability.
