The 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.

Now available in Cool White and Pearl Nebular Black.
Key features
- 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-rotat
- 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
- 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
- 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.
