Outboard engine DF300B

gasolineboating4-stroke

Built for the everyday captain. 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. 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 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.
