A Force to Match the Power of Nature and the Sea
Representing Suzuki’s Identity and Heritage
A Symbol of Our Passion and Commitment
to the Ultimate in Marine Innovation
We are proud to introduce our 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 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 outboard is the ultimate choice.
The latest high-spec, high-output outboards all require high-octane fuel. As far as we know, there is no outboard over 300 horsepower that runs on RON 91, which is regular fuel in some markets.
The reality is, not everyone in the world can easily obtain high-octane fuel. Despite this, we wanted all of our Suzuki fans to be able to experience and enjoy our newest technology, no matter where they are in the world. We wanted them to be able to try the engine with the same fuel as the DF2.5. That is how the DF325A came to be.
The DF325A is packed with the very latest outboard technologies. Among them, we are confident that the Dual Propeller System will provide the ultimate boating experience.
Slick acceleration delivers a straight and true response. The DF325A has the ability to trace the exact line that the driver imagined - as if it were running on a rail. It’s also got brilliant deceleration with a total of 6 blades moving at the same time – yet another Suzuki innovation.
Suzuki’s outboards are continually developed and evolved with our customer’s needs in mind and they are still evolving as we speak.
Experience Suzuki’s newest high-end model, the one worthy of being named the ULTIMATE outboard motor.
The dual prop system efficiently turns 325 horsepower output into propulsion under water.
As an added benefit, because each propeller rotates in a different direction, exceptional stability is achieved.
The DF325A is equipped with a double louver at the air intake to remove water from the air taken into cowl.
The double louver removes water from the air. Incorporating a direct intake system, Suzuki’s dual louver system contributes to higher engine output.
Dual injectors deliver just the right amount of fuel at just the right time into the cylinder.
This dual injector contributes to higher output and better fuel efficiency.
The Offset Driveshaft allows us to make our engines smaller by moving the outboard’s centre of gravity forward, while improving weight distribution, power output, balance and reducing vibration.
The DF325A outboard also incorporates a 2-Stage Gear Reduction which results in a large reduction gear ratio. It delivers powerful torque for quick acceleration and great top-end speed.
A new engine cover design provides the direct intake system with a smoother, cooler flow of air boosting engine operating efficiency.
Fuel efficiency matters whether you’re boating for pleasure or profit. Our Lean Burn Fuel Control Technology predicts fuel needs according to operating conditions, then delivers the optimum fuel/air mixture to the engine. The system is designed to save fuel both at low speeds and up into the cruising range.
Our sophisticated drive-by-wire system eliminates the friction and resistance of mechanical control cables. This gives smooth, precise control with crisp, immediate shifting, particularly at low revs and when maneuvering. The system can be configured with single, twin or triple installations, and for dual stations. Combined with our Lean Burn Control System, it helps improve fuel efficiency over a wide operating range.
Variable Valve Timing is used to vary intake timing with the camshaft to optimize timing for low to mid-range operation. This allows the engine to deliver maximum power output across its entire operating range producing greater low to mid-range torque for powerful acceleration. The entire process happens automatically leaving you to enjoy the power and performance.
The timing chain runs in an oil-bath, so it never needs lubricating, and is equipped with an automatic hydraulic tensioner, so it remains properly adjusted at all times. Simple, effective and maintenance-free.
The engine’s cooling system relies on water supplied through low water intakes located on the lower unit. Utilizing this dual low water inlet configuration increases water flow into the lower unit, delivering greater cooling efficiency. Positioning the forward inlet by the gear case nose delivers a greater water supply, especially at high speeds. The second inlet is also positioned lower allowing the DF325A to operate in shallow water.
The location of oil filter is easy for maintenance.
