V6 350-300HP
DF350AMD

A revolution in innovation. Suzuki has honed its technical capabilities with the aim of providing customers with an ULTIMATE Marine Life.


Integrated Steering System
The Integrated Steering System enables rigging without external steering cylinder, resulting in a cleaner motorwell and an elegant appearance.
With the conventional external cylinder, there are cases that the external cylinder interferes with the motorwell depending on the boat type. However, this Integrated Steering System eliminates such worries and is compatible with various types of transoms.
Dual Prop System
The dual prop system efficiently transmits the horsepower output into propulsion under water.
As an added benefit, because each propeller rotates in a different direction, exceptional stability is achieved.
In addition, the contra-rotating propellers produce a strong reverse thrust.
DURABILITY & RELIABILITY
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.Advantage
- More durability compared to belt types of same class.
- Maintenance-free.

SUZUKI ANTI-CORROSION FINISH
Special protection is applied to the aluminum surface using high strength bonding to protect the aluminum made exterior parts.
Advantage
- Protection against corrosion helps increase the overall outboard durability.

WATER DETECTING SYSTEM
It helps to protect the engine from water in the fuel using a water detecting fuel filter to alert the driver with both visual and audio warnings when water is present in the fuel.
Advantage
- Prevents water in fuel, which can be the cause of issues like poor combustion, lower power output and corrosion.
TILT LIMIT SYSTEM
Tilt Limit System prevents the outboard from tilting beyond a selected angle.
Advantage
- Prevents damage to the boat or outboard due to excessive outboard tilting.
SDSM+
This app enables you to make a plan for boating with the weather forecast and check the engine condition & operation tips for the next boating. All functions are available for free.*
Please check the details from here.
*SMD/SMG4 and a smartphone running Android/iOS are required.
Advantage
- Possible to make a plan for boat trip with checking the weather forecast in advance.
- Check up on the engines before the departure based on the engine data.
- Acquire the engine data by scanning the QR code.
- Provide the engine data to dealer and ask for maintenance easily.
KEYLESS START SYSTEM
This system allows you to start the engine by having the key-fob nearby.
- One push Start & Stop is available
- OAvailable to control up to 6 outboards
- OWaterproof Float Key Fob
- OSecurity support with immobilizer
Advantage
- No ignition key necessary.
- Provides high security. img/img-tec06.jpg

PERFORMANCE
OFFSET DRIVESHAFT
The engine powerhead is positioned closer to the front, moving the outboard’s center of gravity forward.
Advantage
- Less vibration
- More compact
- Stable steering performance
2-STAGE GEAR REDUCTION
This system which incorporates the Offset Driveshaft features a first stage reduction between the crankshaft and drive shaft, and a second stage reduction inside the gear case. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller.
- Increased power to turn large diameter propellers, offering quick acceleration.
- High propulsive efficiency with large diameter propeller.
- Powerful navigation, maintaining propeller rotation even with a larger load.
VARIABLE VALVE TIMING SYSTEM(VVT)
The Variable Valve Timing is used to control the opening and closing timing of the intake valve depending on the engine operation.
Advantage
- Offers smooth, powerful torque.
- Provides increased acceleration during operation for all speed ranges.

DIRECT AIR INTAKE
Designing a direct airflow path from the intake port to the cylinder suppresses any increase in the intake temperature and improves combustion efficiency.
Advantage
- Delivers higher power output from a small displacement with improved combustion efficiency.
EASE & COMFORT
INTEGRATED STEERING SYSTEM
The conventional external hydraulic cylinder is built into the outboard motor.
Advantage
- Simple appearance of the motorwell when rigging
- Prevent from hitting the motorwell when tilting up
- Allows to rig to various types of boats
- Easy rigging
SUZUKI PRECISION CONTROL(ELECTRONIC THROTTLE AND SHIFT SYSTEM)
Operation from the remote control is delivered to the outboard via an electric signal and not by the traditional mechanical control cables.
Advantage
- Less friction and resistance compared to the mechanical type that uses actual control cables.
- Combined with the Lean Burn Control System, it offers improved fuel economy for a wide range of speed.
- Available to control up to 6 outboards.
- 1 lever operation for multiple outboards is available. (for dual top mount only)
- "SELECT" and "THROTTLE ONLY" switch are integrated into the controller.
- Automatic Trim system is available by using with SMG4/SMD.


NOISE REDUCTION
Intake noise is suppressed with silencer and resonator, which makes the noise from the outboard quieter.
Advantage
- Less noise, making boating more pleasant.
SUZUKI TROLL MODE SYSTEM*
This system helps the boat running at a certain speed range in low revs.
Advantage
- Boat can keep running at a certain speed range in low revs without having to operate the throttle on the boat.
- Gives you highly precise control at low revs.
*Available with SMD, SMG, or Troll Mode Switch Panel

SUZUKI EASY START SYSTEM
Simply turn the key and release, and the starter stays engaged until the engine starts. This system offers a smoother start of the engine.
AUTOMATIC TRIM
The Automatic Trim adjust trim angle automatically depending on the engine RPM without your control.
Advantage
- This technology helps to keep appropriate position and contribute to achieve faster top speed and higher fuel efficiency.
*Available with SMD/SMG4

ECOLOGY & ECONOMY
LEAN BURN
The Lean Burn Control System supplies the appropriate amount of fuel and air mixture depending on the navigation conditions.
Advantage
- Significant improvement in fuel economy in all speed ranges especially at cruising speed.
- Fuel is saved and gasoline costs are cut thanks to improved fuel economy.
