Lean Burn
DF9.9B and up (excluding DF250/225/200, DF150W)
The Lean Burn Control System supplies the appropriate amount of fuel and air mixture depending on the navigation conditions.
Advantages:
- 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.
Compared to the original V6 DF200, the new DF200A delivers up to a 19% increase in fuel efficiency mainly in the cruising range (around 70% of its maximum speed).
*Data used in the graphs were obtained through “In-House Suzuki Testing” under uniformed conditions. Results will vary depending upon operating conditions (boat design, size, weight, weather, etc.)
Offset Driveshaft
DF70A and up
The engine powerhead is positioned closer to the front, moving the outboard’s center of gravity forward.
Advantages:
- Less vibration
- More compact
- Stable steering performance
2-Stage Gear Reduction
D70A and up
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.
Advantages:
- 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.

Suzuki Precision Control - “Drive by Wire” S.P.C.
(Electronic Throttle and Shift Systems) Optional:DF350AMD/300BMD,DF350A/325A/300B, DF300AP/250AP, DF200AP/175AP/150AP, DF140BG/115BG
Operation from the remote control is delivered to the outboard via an electric signal and not by the traditional mechanical control cables.
Advantages:
- 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.
Advanced drive-by-wire technology provides superior control and easier rigging for single, twin, and triple motors. Designed for the world’s first 300 HP 4-stroke outboard motors Suzuki’s Precision Control is a computer based, drive-by-wire electronic throttle and shift system that puts unprecedented power right at the boater’s fingertips. Using advanced electronic technology, the system delivers precise throttle control and instantaneous, decisive shifting while eliminating the friction and resistance often associated with mechanical cable controls.
Self-Adjusting Timing Chain
DF40A AND UP
Operation from the remote control is delivered to the outboard via an electric signal and not by the traditional mechanical control cables.
Advantages:
- 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.
VVT (Variable Valve Timing)
DF350AMD/300BMD,DF350A/325A/300B, DF300AP/250AP, DF250, DF200AP/175AP/150AP,DF200A/175A
The Variable Valve Timing controls the opening and closing timing of the intake valve depending on the engine RPM.
Advantages:
- Offers smooth, powerful torque.
- Provide smooth acceleration over all speed ranges.
Suzuki Selective Rotation
DF300AP/250AP/175AP/150AP
Function for selecting regular or counter rotation on one outboard with an optional connector and a counter rotation propeller.
Advantages:
- Either regular or counter rotation can be used on the same outboard.
Multi-Stage Induction
DF350AMD/300BMD,DF350A/325A/300B, DF300AP/250AP, DF250, DF200AP/175AP/150AP,DF200A/175A
Manifold pipes are switched between short and long during low speed and high speed operation to ensure the right volume of air enters the engine.
Advantages:
- Increases output during high speed operation with greater volume of air input.
- Increases combustion efficiency and maximizes torque by increasing the density of the air intake during low speed operation.
Suzuki Troll Mode Sytem
(Optional for Remote Control Models) DF40A and up (excluding DF250/225/200, DF250W, DF150W, DF90AWQH)
(Optional for Remote Control Models) DF40A and up (excluding DF250/225/200, DF250W, DF150W, DF90AWQH)
Advantages:
- 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 RPM.
*Available with SMD, SMG4, or Troll mode Switch Panel
Noise Reduction
DF350AMD/300BMD,DF350A/325A/300B, DF200AP/175AP/150AP, DF200A/175A/150A, DF140BG/115BG
Intake noise is suppressed with silencer and resonator, which makes the noise from the outboard quieter.
Advantages:
- Less noise, making boating more pleasant.
Suzuki Dual Prop System
DF350AMD/300BMD,DF350A/325A/300B
The Suzuki Dual Prop System spins two propellers rotating in opposite directions on a single engine.
Advantages:
- Achieve superior stability when driving straight by eliminating the lateral forces associated with a single propeller.
- Engine power is transferred to the water more efficiently.
- Powerful reverse thrust and braking force.
- Less water resistance due to the small size of the gear case.
- Good water gripping performance and quick startup acceleration.
