Unmatched Performance with Dual Contra‑Rotating Propellers
The DF300B is the world’s first 300 hp outboard to feature a Suzuki Dual Propeller System. This dual, contra‑rotating design delivers superior underwater “grip,” distributes engine torque evenly across two propellers and allows for smaller, more hydrodynamic gear cases without sacrificing performance.
Optimized Power Delivery with Suzuki 2‑Stage Gear Reduction
The integrated Suzuki 2‑Stage Gear Reduction boosts torque while keeping the gearbox compact. The result is a lighter, higher‑efficiency motor that runs smoothly on standard 87 octane fuel.
Compact Design with Offset Drive Shafts
An offset drive shaft places the crankshaft ahead of the power line, shifting the outboard’s center of gravity forward. This compact layout reduces vibration and improves handling in tight marina turns.
Precision Control for Seamless Operation
The DF300B uses a computer‑based Precision Control System—an advanced drive‑by‑wire technology that eliminates mechanical cable friction. Shifts are instant, smooth, and especially responsive at low RPMs, making navigation through crowded waters effortless.
Smart Knock Sensor for Longevity
A built‑in knock sensor monitors combustion to optimize engine performance while enhancing durability. This intelligent system ensures consistent power output in every operating condition.

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 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 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.
