Technical details
Producer:	Suzuki (JP)

Suzuki introduces the DF200AP, which includes similar technologies found in the DF200A as well as new features such as the Suzuki Keyless Start System, Suzuki Precision Control drive-by-wire electronic throttle and shift control and Suzuki Selective Rotation.

Suzuki’s new Keyless Start System replaces the traditional key and keyswitch with an electronic keyfob that transmits an access code to the engine’s starting system. With the keyfob within one yard of the console and the emergency safety lanyard attached, the operator turns on the main switch and presses the start button. The key fob can remain safely in the operator’s pocket. Further, this system serves as a theft deterrent, as the outboards will not start without the proper access code being transmitted by the key fob.

Suzuki’s drive-by-wire system aims to eliminate the friction associated with conventional cable control systems through decisive shifting and smooth throttle response. With Suzuki Precision Control, the DF200AP is also compatible with Suzuki’s optional Precision Maneuvering System for joystick control while docking and electronic power steering while underway.

Suzuki Selective Rotation allows the DF200AP to be set-up to run in either standard or counter rotation, including forward and reverse drive gears and a 2.50:1 gear ratio.

Suzuki's latest lightweight and fuel-efficient model – the four cylinder DF200A

The DF200A delivers the kind of impressive performance one would expect only from a V6 engine – but from just four cylinders, which means it is the lightest in its class. In addition to this the new DF200A benefits from a whole host of high specification features, which deliver real customer benefits:

• Direct air intake and Variable Valve Timing for higher thermal efficiency and exceptional performance.
• 2,867 cm3 “Big Block” displacement and a higher compression ratio for impressive acceleration and low end torque.
• Lean Burn Control Technology for improved fuel economy.
• Knock, O2 and water detection sensors and systems to monitor and control internal engine operating parameters and improve reliability.
• Importantly, the new DF200A weighs in at just 225kg, over 12% less than Suzuki’s current V6 DF200 model.

New styling and new levels of performance
Just one look at the newly designed cowling of the DF200A indicates that this outboard is something special. However, the shape of the cowling represents more than just contemporary styling. Its design and the special baffling underneath work together to provide a semi-direct air intake system that provides cooler air directly to the engine’s long track tuned intake manifold. The engine breathes even more efficiently thanks to Suzuki’s proven Variable Valve Timing system and twin intake and exhaust valves for each cylinder.

By allowing the engine to breathe cooler air, both acceleration and top end speed are improved. In fact, Suzuki factory testing reports a 1.5% improvement in top end speed and an impressive 12% improvement in 0 to 30 mph acceleration when compared to competitive models.

Another contributing factor to these improved performance numbers is the 10.3:1 compression ratio. By increasing compression of the fuel/air mixture by 9.7%, Suzuki engineers have dramatically improved the power output from its impressive 2,867 cm3 displacement DOHC powerhead.

Market-leading power to weight ratio
When it comes to speed and performance, boaters must balance power and weight. Until now, many boaters have had to deal with the weight of a V6 engine in order to achieve the level of performance they desired. Now, with the introduction of Suzuki’s new DF200A, there’s a real alternative to a V6.

With the DF200A weighing just 225kg, boaters can choose a lighter, inline four cylinder engine without sacrificing power or performance. For those boaters in the market for a new boat and motor, or considering repowering from heavier V6 four stroke outboards (or even older two strokes), the new DF200A provides an attractive choice in terms of size, weight and fuel economy, not to mention cost of purchase.

Reliability and confidence through engine management sensors
The addition of Knock and O2 sensors hel KS keep the engine running smoothly. The knock sensor ‘listens’ to combustion, providing information to the ECM to precisely manage engine timing. The O2 sensor monitors engine operating conditions and provides input to the ECM to manage the fuel/air mixture for maximum efficiency and optimum performance.

In addition, the DF200A features a water detection sensor to warn of moisture in the fuel system, a common concern given today’s use of ethanol-blended fuel.

Suzuki’s proven Lean Burn Control Technology
With the introduction of its Lean Burn Control Technology, Suzuki’s engineers have made fuel-efficient four stroke outboards even more economical. By taking full advantage of the computer control afforded by the 32-bit onboard ECM, and through the use of engine sensors monitoring everything from engine timing to ambient temperature, the system is able to provide the precise amount of fuel needed throughout the rpm range.

By utilising Lean Burn Control Technology, the inline-4 DF200A enjoys a significant improvement in fuel economy over Suzuki’s V6 200 horsepower outboard. In fact, Suzuki Factory Testing indicates a 32.6% improvement at top cruising speeds (5000 rpm).

Additional features on new DF200AP models
In addition to the DF200A, Suzuki is also introducing the DF200AP, which benefits from even more technology. The DF200AP will be the first 200HP outboard on the market available with Suzuki Precision Control drive-by-wire controls and Suzuki Selective Rotation. With Suzuki Selective Rotation, dealers can set up engines in either standard or counter rotation, thanks to specially-designed gearing in the lower unit and the engine’s electronic shift controls.

In addition, DF200AP models will feature a keyless ignition system. This system uses a coded keyfob to transmit an access code to the engine’s starting system. When the keyfob is within 60-inches of the main unit of the starting system, the user simply turns on the ignition system switch and starts the engine with the push of a button. When it’s time to leave, the user can turn off the engine, switch the ignition system switch off and head for home.

A new outboard for today’s modern boater
When Suzuki first introduced its line of four stroke outboards over 15 years ago, it pioneered many technologies that are taken for granted today. For example, Suzuki was the first to feature fuel injection on its four strokes, the first to incorporate a long track intake manifold, and when Suzuki introduced the world’s first 200, 225, 250 and 300 horsepower four stroke outboards, it designed its engines consistent with the industry-standard mounting dimensions.

In fact, every Suzuki outboard from the portable DF2.5 up to the flagship DF300AP fit on ABYC-standard 26-inch centres, which is a fact appreciated by any boater considering repowering with new outboards.

As Suzuki has introduced its next-generation four stroke outboards, it has also introduced new technologies, such as Lean Burn Control, that deliver improved fuel economy, performance and reliability.

With a surprisingly low weight, advanced technology like Lean Burn Control, Knock and O2 sensors, as well as performance-enhancing compression and intake specifications, boaters looking for a new 200 horsepower outboard need look no further than the DF200A and DF200AP. The advantages in terms of cost of operation (less weight, improved fuel economy, easier maintenance) and exceptional performance, make this engine a perfect match for all kinds of boats in the leisure and commercial sectors.

Masahiro Yamamoto, General Manager for Suzuki Marine European Liaison Office, said, “Once again our engineers have delivered a ground-breaking new outboard motor. I am privileged to have been able to test the new DF200A and am pleased to report that it delivers outstanding power and has a very satisfying engine note. I am confident that this new model will be hugely popular right across Europe and will cement Suzuki’s reputation for producing outstanding large horsepower outboards.”

The new Suzuki DF200A is set to redefine lightweight outboard performance and fuel economy. The DF200AP will be available in early 2015.

Suzuki outboards, from the smallest up to the 300HP V6s, fit on standard 26-inch mounting centers.
