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

Stealth Performance Lower Unit
The pro?le of the gear case (front), the location and the pro?le of the water ?lters have been changed to improve cruising performance and to prevent cavitation.

Left-right asymmetry brings better steering stability.

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.

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.

Dual Water Inlet
On the DF350A, the best results were achieved when the main intake was positioned at the front of the gear case, with the secondary intake located just above the skeg. This was our ultimate solution to arranging the main and sub intakes as far apart from each other as possible, which Increases the water flow, providing better cooling performance especially at high speeds.

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.

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 DF300B has water inlets on the tip of the gear case, which helps with water suction even when there is dynamic pressure caused by the movement of the gear case through the water.

New Engine Cover Design
Engine top cover, Air intake louver, Engine upper cover grip, Engine cover louver and decals have been newly designed.

Suzuki Precision Control (Electronic Throttle and Shift)
Suzuki Precision Control is a technologically advanced computer-based control system that replaces the mechanical control cables found in conventional control systems with electronic wiring that eliminates the source of friction and resistance. While you enjoy smooth, little friction throttle and shift operation, the system's computer is processing and transmitting commands in real-time to actuators at the engine that deliver precise throttle controls with smoother, decisive shifting. This is most evident in the low rpm range where operation is noticeably smooth and accurate.

When combined with Suzuki's Lean Burn Control System it allows control of fuel and air flow to boost the limit of the controllable revolution range improving fuel economy over a wide operating range. Suzuki Precision Control also features built-in systems that help guard the engine and drive against damage due to mishandling, and its design and simple wiring make installation easy, reducing the time required for rigging and adjustment. The system offers precision control for single, twin or triple installation as well as dual station operation.

Configurable with up to 6 outboards including dual station.

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.

Offset Driveshaft
Suzuki outboards are among the most compact outboards in their respective classes.
That's due in part to our proven offset driveshaft system. This design places the crankshaft in front of the driveshaft through the use of intermediate gear reduction. In addition to providing an increase in power performance and adding to the compactness of the outboard, this system moves the outboard's centre of gravity forward, resulting in better weight distribution and balance, better directional stability, and less vibration.

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
