Suzuki DF140BG Stealth Outboard

The all-new Suzuki DF140BG Stealth is light and compact but delivers inspired performance, giving it the best power-to-weight ratio in its class along with mechanical controls. The DF140BG Stealth provides heavy-duty performance and long-lasting durability in a revolutionary, lightweight package, with our engine cover design that features a large air induction port to provide maximum airflow and maximum muscle.

STEALTH LINE
Suzuki Marine's new Stealth Line now offer more of the innovative technology and uncompromising power with sleek new matte black style.

Quiet Operation
Suzuki four-stroke outboards have long been noted for their exceptionally quiet operation. Suzuki engineers go to great lengths incorporating methods designed to keep outboard operation as quiet as possible. In a noise comparison test between the DF200A and a competing 200HP in-line four-stroke outboard, the results clearly show that the DF200A runs quieter than its competitor.

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.

Suzuki Micro Plastic Collecting Device (MPC)
Suzuki's Micro-Plastic Collecting Device (MPC) is part of Suzuki's Clean Ocean Project initiative, which collects micro-plastic by filtering the returning ocean water after it has been used for cooling the outboard motor., without any effect on performance when boating.

Improved Gear Case
By optimising the gear oil passage, the spinning pinion gear generates negative pressure and it helps gear oil circulation.

ADVANTAGE: It lowers gear oil temperature and contributes to the increased durability of pinion gear

Increased Alternator Output
Newly designed ventilation which improves cooling around the coils.

ADVANTAGE: 3Amp higher alternator output at idle speed range that is roughly equivalent to the necessary output required to operate the SMD12/SMD16 displays.

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.

ADVANTAGES

• High Torque even with big loads.
• Powerful enough to rotate a larger propeller

Lean Burn Control System
The Lean Burn Control System supplies the optimal 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 petrol costs are greatly reduced thanks to the improved fuel economy.

More Features to contribute to Durability

• Large capacity Fuel Pump: Capable to rig on various kinds of boats
• Optimized O? Sensor mounting position: Increased Durability
• Using Zinc-containing Rustproof Coating bolt: Increased Durability

Water Detecting System

• It helps to protect the engine from water in the fuel.
• Using bigger fuel filter than the DF140A/115A.
• Optimised Fuel Filter position.

ADVANTAGE

• Can avoid water in fuel.
• Increased Durability & Reliability.
• Easy replacement of fuel filter.

Direct Ignition
Integrates the ignition coils into the spark plug caps.

ADVANTAGES

• Reduces the number of parts and simplifies the wiring system.
• Removing the high tension cord enables the ignition to generate spark efficiently which leads to the improvement of combustion efficiency.

Newly Designed Air Intake System
The air intake structure was reviewed and improved.

ADVANTAGE

• Delivers higher power output.
• Increased ability to remove water from air taken into cowl.
• Decrease in the air intake temperature.

Easy Maintenance
Specially designed to be easy for owners to perform maintenance tasks.

ADVANTAGES

• Easy access oil filter: Can be replaced simply by removing the top cover.
• Oil Spill Catcher: A tray is added around the oil filter to catch oil which comes out when exchanging the oil filter
• Oil Level Gauge: Able to use ?15 oil changer hose

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.

Suzuki Easy Start System
Starts are quick and easy with Suzuki's Easy Start System. No need to hold the key, just turn it once and the starter system stays engaged until the engine starts. The system delivers smoother and improved starts to get you up and running quicker.

Quiet Operation
Intake noise is suppressed with a resonator, resulting in quieter noise output.

ADVANTAGE: Less noise, making boating more enjoyable.

Offset Drive Shaft
The engine powerhead is positioned closer to the front, moving the outboard's centre of gravity forward.

ADVANTAGE

• Less vibration.
• More compact.
• Stable steering performance.

Suzuki Anti Corrosion Finish
Suzuki's Anti Corrosion Finish is specially formulated to increase the durability of the engine and help protect parts of the outboard's aluminium exterior. This advanced finish is designed for maximum bonding of the finish to the outboard's aluminium surface, creating an effective treatment against corrosion.

Suzuki Keyless Start System
Suzuki's Keyless Start system utilises a proximity key fob that transmits an access code to the engine's starting system. As long as you have the key fob on your person, all you need to do is stand within one meter of the console, connect the emergency switch code, turn on the main switch, then start the outboard with a push of a button. With the key remaining safely in your pocket, the system offers simple, stress-free operation while reducing the risk of a lost key. The system also makes for an excellent theft deterrent since the outboard will not start without the proper access code. The key fob also floats so should it ever go overboard you can retrieve it.

Tilt Limit System
To protect the boat and motor from damage that can occur when tilting the motor, both outboards incorporate a user adjustable tilt limit switch that prevents the outboard from tilting beyond a predetermined point.

Suzuki Troll Mode System (Optional Equipment)
Suzuki's Troll 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.

Suzuki Water Detecting System
Water in the fuel can be the source of poor combustion, lower power output, and corrosion. To help protect the engine from moisture in the fuel, a water detecting fuel filter is fitted to alert the operator with both visual and audio warnings when water is present in the fuel.

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.

Features:

• Shaft length: Available in 20" & 25"
• Colour: Pearl Nebular Black
• Electric starting system: Simply turn the key and release, and the starter stays engaged until the engine starts. (Keyless start system option is available on selected models)
• Power Trim and Tilt: With the push of a switch, change the outboard's thrust angle, or tilt the outboard up or down
• Regular rotation propeller: The outboard propeller operates in clockwise rotation, meaning to the right
