A Groundbreaking Four‑Stroke Outboard
The 2025 Suzuki DF300B is the world’s first 300 HP, four‑stroke outboard that delivers unmatched torque thanks to its dual contra‑rotating propeller system. This innovative design gives you superior thrust while keeping gear size compact and hydrodynamic.
Key Performance Highlights
- Dual Contra‑Rotating Propellers: Distributes engine torque evenly, reduces individual propeller load, and allows for a smaller, more efficient gear case.
- Offset Drive Shafts: Shifts the crankshaft forward to lower the center of gravity. The result is a lighter, tighter handling outboard with reduced vibration.
- Precision Control System: A computer‑based drive‑by‐wire setup replaces heavy mechanical cables for smoother, crisper shifting—especially noticeable at low speeds around tight marina turns.
- Knock Sensor Technology: Continuously monitors combustion to optimize power output and enhance engine durability.
Built For Everyday Use
The DF300B runs on standard 87 octane fuel, making it ideal for everyday operations on larger vessels. Available now in Sleek Cool White or Elegant Pearl Nebular Black finishes, this outboard combines style with performance.
Suzuki Marine – The Ultimate Four‑Stroke Outboard Motor
Built for the everyday new DF300B is the world’s first 300 HP, four-stroke outboard with dual contra-rotating propellers. The breakthrough combination of the Suzuki Dual Propeller System and the Suzuki 2-Stage Gear Reduction aid to successfully produce better torque, engineered especially for heavy models. DF300B has been engineered to run on 87 octane fuel, perfect for everyday use on larger boats. This truly is Suzuki’s ultimate Four-Stroke Outboard Motor. Now available in Cool White and Pearl Nebular Black.

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.
