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.

Gear Case Design
Gear Case DesignAt high speeds cavitation can cause significant losses in speed and grip. The New DF325A overcomes this with a highly advanced gear case design. Computational fluid dynamics (CFD) and countless test drives, have resulted in a breakthrough design that not only minimises resistance but also provides a highly efficient flow of water to the propellers.
High Reverse Thrust
High Reverse ThrustWith six blades rotating, the contra-rotating propeller produces a strong reverse thrust. The materials of the new DF325A gears are ultra-strong to withstand the new high loads and feature special heat treatment to give additional strength and reliability.
Dual Injectors for Cooling & Power
Dual Injectors for Cooling & PowerInjecting fuel achieves two things, it atomises the fuel and it cools the cylinder. To provide the power and cooling needed, the fuel must be completely injected at precisely the right time and angle. The all new Dual Injector System uses two smaller injectors giving immense precision, improved atomisation and increased fuel efficiency.
Attention to detail
Attention to detailWith the higher compression ratio, more is being asked of the piston than ever before. Not only does the surface have to withstand greater forces, but the connecting rod and hardware do too. To help the piston withstand the added lateral pressure, a switch has been made from the standard surface texture treatment to shot peening. Shot peening creates fine dimples on the surface that evenly distribute the pressure created during combustion. It’s a more expensive, and a far more involved manufacturing process, but one that makes it possible to create a piston worthy of the “ULTIMATE” title.
Suzuki Selective Rotation
Suzuki Selective RotationNormally, when using multiple outboards, a combination of standard and counter rotating engines are mounted.
Suzuki Selective Rotation, available on our AP series outboards, eliminates the need for different models, as any model can be easily programmed to run in either direction. The DF325A’s contra-rotating propeller technology takes this process one step further by enabling mounting either side at the same time as eliminating steering torque and maximising true and straight propulsion forces.
Dual Water Inlet
Dual Water InletDual water inlet is a technology developed to cool the engine with minimal friction loss, using a combination of a small water pump and dynamic water pressure. Conventional outboards have water inlets on the side of the strut of the gear case. However, at very high speed, the water pressure at the strut surface is reduced, making it difficult to maintain stable water suction. The DF325A has water inlets on the tip of the gear case, taking advantage of the dynamic pressure caused by the movement of the gear case through the water.
Suzuki Troll Mode System
Suzuki Troll Mode SystemSuzuki’s Trolling Mode system provides finer control over engine speed at low rpms to keep your boat moving at a constant speed while trolling. When the system is engaged, revs are controlled with an independent control switch that adjusts engine revs in 50rpm increments over a range spanning from idle to 1,200rpm. The system includes a control switch, which can be mounted nearly anywhere on the console, and a tachometer, and is compatible with Suzuki’s SMIS digital gauges or the dual scale analogue gauges.
Self-Adjusting Timing Chain
Self-Adjusting Timing ChainThe 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.
Variable Valve Timing (VVT)
Variable Valve Timing (VVT)Suzuki’s engineers designed the 4.4-liter V6 engine with an aggressive cam profile that delivers maximum output and performance at high rpm. In coupling this cam profile with Suzuki’s advanced Variable Valve Timing (VVT), the DF350A delivers the additional torque that outboards need for accelerating in the low to midrange. VVT achieves this by adjusting the timing of the intake valves, allowing them to open before the exhaust valves are fully closed, creating a momentary overlap in the timing where both sets of valves are open. Using VVT, this overlap can be increased or decreased by altering intake timing with the camshaft resulting in optimum timing for low and mid-range operation.
Precision ControlThis technologically advanced 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 and when manoeuvring around the marina and in close quarters. The system is configurable for single, twin, triple, or quad installations, and for dual stations.
Lean BurnSuzuki’s innovative Lean Burn Control System was first introduced on the DF90A/80A/70A to great acclaim. The system predicts fuel needs according to operating conditions, allowing the engine to run on a leaner, more efficient air fuel ratio. It delivers its benefits over a wide operating range, providing significant improvements in fuel economy from low-speed operation into the cruising range. In combination with Suzuki Precision Control electronic throttle and shift system, the operator can precisely, and smoothly, increase or decrease engine RPM for significantly improved fuel economy.
2-Stage Gear Reduction
2-Stage Gear ReductionThe 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.
