Power with Passion

We are proud to introduce our NEW DF325A – an outboard that perfectly balances awesome power and thrust, with outstanding fuel-efficiency and trusted reliability all within a lightweight and stylish design.

Built with the every-day use of larger boats in mind, this market-leading new outboard has been engineered to run on 91 RON fuel and, as a world-first, is the first four stroke outboard over 300 horsepower to do so.

The high-tech and innovative DF325A has been designed to be robust, easy to use and versatile, making it the ideal outboard for large boats whatever the task. Whether you are using your boat for work or play, wherever you are in the world, this new outboard is the ultimate choice.

Huge Power with Maximum Efficiency

Suzuki engineers set out to create a compact, lightweight outboard that combined the high power required, alongside the operating efficiencies that cannot be achieved by using traditional technologies such as turbocharging or supercharging. Additionally, they set the goal of making the DF325A run on low octane, 91 RON fuel, which combined with legendary Suzuki reliability makes this outboard ideally suited for a wide variety of large boats around the world.

Dual Prop System – a true revolution in propellers

Suzuki’s engineers know that the lower unit shape and propeller design has a critical impact on performance. The innovative contra-rotating propeller design provides more grip underwater and also helps to achieve a smaller, and far more hydrodynamic gear case. It does this by distributing the engine’s torque evenly over two propellers, so that the torque per propeller is decreased enabling the gear diameter to be reduced. A new three-blade/three-blade propeller set up has been developed to provide incredible acceleration and high performance. In testing, this configuration recorded high speeds even under heavy load and at high rotation speeds. The propeller blade geometry has also been optimised to work in the new configuration resulting in incredible grip and acceleration across the rev range. One of the most remarkable benefits is exceptional directional and transverse stability which is achieved by each propeller rotating in different directions, to balance the turning.

10.5:1 Compression Ratio for Efficiency

Designing the ultimate Suzuki outboard with more power is always done against the benchmarks of lighter weight and more power. The new DF325A features our proven 4.4 litre displacement block giving tremendous torque and making it the largest displacement V6 on the market today. Plus, with a compression ratio of 10.5:1 the DF325A also delivers impressive fuel economy and reliability.

Suzuki Dual Louver System, Direct Air Intake

Suzuki engineers have designed an air intake system that allows the engine to draw in ample fresh air, while separating out water, spray and moisture. Dual louvers under the hood trap larger water droplets and then moisture as it enters the engine cowling, resulting in zero water intake during testing. In addition, intake air temperatures are, on average, 10º cooler than ambient, providing the combustion chamber with cooler, denser air for a more powerful cycle.
