to the Ultimate in Marine Innovation

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.

3 + 3 years Recreational Warranty

All recreational/privately registered Suzuki Outboards come standard with 3-years / unlimited hours manufacturer’s warranty. Recreational outboards are also eligible for a bonus 3-year Warranty providing that an authorised Suzuki Marine Dealership completes servicing as per the owners manual schedule. The Suzuki dealer must use only genuine parts and oils during both manufacturer’s and bonus warranty periods.

Features

Gear Case Design

At 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

With 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

Injecting 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

With 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

Normally, 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 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’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

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.

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 Control

This 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 Burn

Suzuki’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

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.
