CHARACTERISTICS

Semi-direct air intake system
A custom-designed semi-direct air intake system is designed to deliver consistently cooler air to the interior, while a four-valve-per-cylinder DOHC powerhead with variable valve timing allows the engine to "breathe" for more efficient acceleration. and at top speed. In addition, Suzuki's fuel injection system and Lean Burn technology offer extra fuel economy.

Big Block - High Performance Engine
With the DF200A, our aim was to build an outboard engine that delivers all the power and performance of a 147kW (200PS) class V6 outboard, using a lighter and more ergonomic four-cylinder configuration. To reach this level of performance, our engineers used an inline four-cylinder engine, with a capacity of 2.9 liters, and a higher compression ratio of 10.2:1, to create impressive acceleration and low-end torque.

Semi-direct air intake system
The casing on the new DF200A has a modern design, giving it an innovative look. Beyond that though, design is a matter of function. Integrated into the hood is a semi-direct air intake system that delivers cool air directly to the engine's multi-stage intake unit. Engines that "breathe" cold air are able to increase operating efficiency resulting in greater acceleration and top speed.

The cowl design also helps reduce the temperature inside the engine with ports that allow the rotating flywheel to push hot air through the cowl and out.

Silencer
The engine exhaust system is a well-known source of engine noise, but another, often overlooked, source is the intake manifold. Air drawn into the intake manifold at high speeds can create a harsh sound.

The DF200A's incorporate an air intake silencer that reduces this noise operation making them extremely quiet.

Lean Burn Control System
The Suzuki Lean Burn Control System is an intelligent fuel delivery system that achieves noticeable improvements in fuel consumption making Suzuki's four-stroke engines more economical. By monitoring engine performance and operating conditions in real time, the system uses the onboard 32-bit ECM to predict fuel needs and deliver a more accurate fuel mixture throughout the outboard's operating range. The results show significant improvements in fuel economy across the powerband, including the cruising range where the engine is used most of the time. Comparing the new DF200A to the original V6 DF200, tests show a 19% increase in fuel efficiency mainly in the cruising range (around 70% of top speed).

The data used in the graphs were obtained through internal testing under uniform conditions. Results will vary depending on operating conditions (boat design, size, weight, weather, etc.)

Oxygen Sensor Control System
Like many of Suzuki's high-end outboards, the DF200A features an O2 feedback control system, which helps maintain optimal engine performance. The system monitors engine operating conditions to provide input to the ECM, allowing it to manage the fuel/air mixture for maximum performance throughout the engine's operating range.

Big Block—High Performance Engine
The design goal for the new DF200A was to provide users with the performance of a V6 DF200 outboard from a more compact, lighter four-cylinder engine. To this end, Suzuki engineers started with the 2.9-liter inline four-stroke engine used in the DF150 / 175, updating the "Big Block" design with a DOHC four-cylinder with 4 valves per cylinder and a 10.2:1 compression ratio. Additionally, the engine incorporates variable valve timing, multi-stage intake and a 32-bit onboard computer. The end result is an engine that weighs 30kg less than its V6 version, making it an excellent choice for installation on small and large boats. It is also an excellent choice for those looking to upgrade older boats equipped with two-stroke V6 engines.

Variable Length Insertion System (MSI)
Getting the right amount of air into each cylinder has a big effect on performance. High speed mode usually requires longer

Higher Compression Ratio 10.2:1
Drawing on our experience in building motorsports engines, Suzuki engineers designed the DF200A series four-cylinder engine with a higher compression ratio of 10.2:1. The higher compression ratio achieves a noticeable improvement in performance and power output from the 2,867cc engine. .

The largest capacity in its class
Capacity has a direct effect on acceleration and torque. Generally speaking, the more cubic the more power. For this reason, the DF200A was designed with a displacement of 2,867cm3 making it the largest available in the four-cylinder engine class with 147kW (200PS).

VVT (Variable Valve Timing)
Variable valve timing is used in many of Suzuki's top-of-the-line outboards to provide high performance throughout the engine's operating range while retaining the benefits of four-stroke technology. The system starts with an innovative cam profile designed for maximum efficiency and high-rpm performance. Variable valve timing is used to metabolise intake timing with the camshaft to optimize timing for low to mid-range operation. This allows the engine to deliver maximum power output throughout its operating range, producing more low- to mid-range torque for strong acceleration. The whole process is done automatically leaving you to enjoy the power and performance.

Smooth operation
Weight Compensation System
One of the inherent characteristics common to in-line four-cylinder engines when operating at high rpm is an aftershock that lines up directly with the piston movements. To counteract this vibration, Suzuki engineers use a secondary balancing system that compensates for piston movement with horizontal motion. To achieve this, the balancer is split into a left and right section each of which rotates in the opposite direction at twice the speed of the crankshaft, effectively compensating secondary vibrations and achieving smoother engine operation.

Silent mode
Suzuki four-stroke outboards have long been recognized for their exceptionally quiet operation. Suzuki engineers go to great lengths to incorporate methods designed to keep outboard operation as quiet as possible. In a noise comparison test between the DF200A and a competing 147kW (200PS) four-stroke engine, the results clearly show that the DF200A runs quieter than its competitor.

Soft Type Elastic Bases
The new DF200A incorporates a combination of soft type and high thrust rubber mounts on both upper and lower mounts to reduce engine vibration and provide stable operation. Soft-type rubber mounts are used to absorb the vibrations produced at idle through 2,000 rpm. while high strength rubber mounts provide stable operation under high loads increasing power and efficiency.

Shifted Central Axis
Pioneered by Suzuki, the use of the drive shaft in four-stroke outboards has long been used to reduce the size of the outboard. Found on all four-strokes from the DF70A up, this design places the crankshaft ahead of the drive shaft while simultaneously moving the outboard's center of gravity forward. While the design contributes greatly to the overall compact drive and increased power output, it also moves the engine's inertial axis, the point where engine vibration is at a minimum, above the upper engine mount, thereby significantly reducing vibration. These outboards also incorporate two-stage gearing, designed to take full advantage of the power produced by these high-performance engines. Providing a final gear ratio of 2.50:1 - the largest you can find on any of these outboards in this class - it offers strong torque for quick acceleration and a long top speed.

Advanced Features Only Available on DF200AP
Selective Rotation System
Large boats fitted with multiple outboards generally couple a normal external rotation with a counter-direction model to keep the boat in a straight line. Once the purchase of a special counter-rotation model is required, Suzuki's innovative Selective Rotation technology eliminates that need by incorporating a special unified design of gears, shaft and foot bearings that allow the outboard to operate reliably and efficiently in any direction.

Available only on the DF200AP, the reverse rotation function requires an optional enable switch connected to a circuit inside the engine compartment plus the installation of a reverse rotation propeller*3.

*3: Consult your dealer before changing standard rotation to reverse (or vice versa).

The optional switch and additional propeller are needed to change the rotation of the outboards.

Accuracy Control System
Available only on the DF200AP, Suzuki Precision Control is an electronic throttle and shifter system that replaces manual transmission control cables with a digital navigation system to eliminate friction and drag at the controls. The system provides smooth and precise control with immediate responses that are particularly useful during low-rpm operation and during manoeuvring.

Combined with the Suzuki Lean Burn Control System, the system also helps improve fuel efficiency across a wide range of modes.

Suzuki Precision Control also features safeguards to help protect the engine from damage caused by mishandling and is compatible with single, dual or triple installations as well as dual station operation.

Advanced Electronic Systems
32-Bit ECM (Engine Control Unit)
The DF200As are equipped with a 32-bit ECM (Electronic Engine Control Unit) that provides precise control over engine operation, particularly the ignition and fuel delivery systems. This powerful on-board computer monitors and processes key data collected in real-time from an array of sensors placed in areas vital to the engine's operation. These sensors include the Manifold Absolute Pressure Sensor, Intake Air Temperature Sensor, Shift Position Sensor, Throttle Position Sensor, Cylinder Wall Temperature Sensor, Camshaft Position Sensor, and Exhaust Manifold Temperature Sensor. Using this data, the computer provides precision control of the engine's ignition and fuel systems by maintaining optimal spark and fuel delivery under all operating conditions.

Energy Exchanger
These days boats are equipped with a wide range of electronics that require an abundant flow of power to keep them running. On the other hand, the DF200A is equipped with an alternator designed to produce the majority of the maximum 44A (12V) power with the engine running at a low speed of 1,000rpm - idle for most circumstances.

Electronic serial multi-point fuel injection
Suzuki pioneered the use of electronic fuel injection in four-stroke outboards with the launch of the original DF70 / 60 in 1997. The multi-point Suzuki Sequential Electronic Fuel Injection provides each of the engine's cylinders with an optimized mixture of fuel and air that is introduced into the cylinder to high pressure as commanded by the 32-bit ECM. The system offers improved fuel economy, instant acceleration and reduced emissions that meet emissions standards. It also complies with the standards of the Recreational Craft Directive (RCD), Directive 2003 / 44EC of the European Parliament and of the Council and received a 3-star rating from the California Air Resource Board (CARB).

Designed to offer comfort

Keyless start system*4
Suzuki's new Keyless Start system uses a special key that transmits a password to the engine's starting system. As long as you have this key on you, all you need to do is stand one meter away from the console, connect the emergency switch cable, turn on the main switch and start the outboard with the push of a button. With the key remaining secure in your pocket, the system offers simple, effortless operation while reducing the risk of key loss.

The system also makes an excellent theft deterrent as the outboard will not start without the appropriate password. The key fob also floats, so if it gets lost in water you can retrieve it.

*4:Availability may vary in some regions. For more information, contact your local Suzuki dealer.

Water-cooled voltage regulator with isolator
Water-cooled voltage regulators built into both outboards dissipate heat in the regulator to improve durability. The battery charging system also incorporates an isolation function that allows the use of two batteries.

The system splits the electricity between two circuits and is designed to protect the primary battery in the event that the secondary battery drains.

Insurance box
Fuses for the outboard's electrical system are housed in a fuse box located on the side of the outboard motor. This design keeps the exterior of the engine clean while providing easy access.

Slope Limit System
To protect the boat and engine from damage that can occur when the engine tilts, both outboards have a built-in user-adjustable tilt limit system that prevents the outboard from tilting beyond a predetermined point.

Double Engine Cleaning Port
Over time, salt, sand and dirt build-up can restrict flow in the cooling system causing damage. To prevent this buildup, both outboards are equipped with two water purge ports that make flushing the cooling system as easy as possible. With one port located on the left side of the leg and a second on the front panel, you will always have easy access to the flushing system, whether the boat is in or out of the water.

Impact sensor
Located on the DF140A and DF115A, the knock sensor monitors combustion to provide the ECM with the information needed to precisely manage engine timing for optimal performance. In addition to maximizing power, the system also helps increase engine durability.

Water Detection System
Water in the fuel can lead to problems including poor combustion, lower power and engine corrosion.

Suzuki's Water Detection System is designed to protect the engine from fuel moisture by using a water-sensing fuel filter to alert the operator with visual and audible warnings when water is present in the fuel. The filter is designed to allow you to visually check the water.

Durability and Reliability
Anti-corrosion treatment
To protect against corrosion, Suzuki protects its outboards with its own specially designed anti-corrosion finish. Applied directly to the aluminum alloy of the outboard, this finish provides maximum adhesion of the finish to the aluminum surface. Coating an epoxy primer substrate, a black metallic finish and a clear acrylic fiber finish over this is an effective anti-corrosion treatment, protecting those parts of the aluminum alloy exterior that are constantly exposed to salt water.
