Introducing the new lightest-in-class DF100B
Suzuki is known for manufacturing lightweight and compact four stroke outboards and the new DF100B is no different. Suzuki has focused on this important mid-range sector and successfully set out to create the lightest 100ps four stroke outboard available today.
At just 157kg, the new DF100B is 25kg lighter than the existing DF100A and 6kg lighter than the closest competitor model, making it the ideal power unit for a wide range of boats. High output performance is realised in a compact body size with weight of 157kg. It meets customer needs for more compact and higher output outboard model to be fitted on mid-size commercial and leisure boats.
Suzuki has based the new DF100B on a proven design by using the same 1502cc engine unit as the DF70A/80A/90A models. However, it has added even more value to this new model by up-rating the ECM as well as adding a water detection fuel filter. The water detection fuel filter is designed to help protect the engine by alerting the driver when water is present in the fuel.
This new model will be available in ‘Pearl Nebular Black’ or ‘Cool White’ with a large 3D silver ‘S’ emblem to enhance its premium look.

Features
Compact
100ps from a DF90A engine body
Offset drive shaft for compact body
The Largest Reduction Gear Ratio
2.59:1, the greatest reduction gear ratio in 100ps class. (SUZUKI internal research)
Offset Driveshaft
The engine powerhead is positioned closer to the front, moving the outboard’s center of gravity forward.
Advantage:
- Less vibration
- More compact engine
- Stable steering performance
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. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller for high propulsive efficiency while providing higher torque.
Advantage:
- High propulsive efficiency with large diameter propeller.
- Powerful navigation, maintaining propeller rotation even with a larger load.
- Tremendous power to turn large diameter propellers, offering quick acceleration.
Streamlined Gear Case and Highly Efficient Propeller
The lower gear case on all four outboard motors utilizes a hydrodynamic design. As the lower unit moves through the water its sleek form reduces drag by up to 36% compared to conventional designs, contributing to faster acceleration and increased speed.
Thanks to the powerful torque delivered with Suzuki’s two-stage gear reduction, these outboards can turn a large diameter propeller. Suzuki engineered a new highly efficient propeller that takes advantage of this torque to provide faster acceleration and higher top speed.
Water Detecting System
It helps protect the engine from water in the fuel using a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.
Advantage:
- Can avoid water in fuel, which can lead to issues like poor combustion, lower power output and corrosion

Water Detecting System
Helps to protect the engine from water in the fuel using a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.

Self-Adjusting timing chain
Simple, effective and maintenance free timing chain that runs in an oil-bath so it never needs lubricating and equipped with a hydraulic tensioner so it remains properly adjusted at all times.

Tilt limit system
Protects the boat from damage when tilting the outboard, acting as both a tilt limit and trim sender, the step-free, continuous system allows you to install the outboard on almost any boat.

Lean Burn Control Technology
Suzuki’s Lean Burn Fuel Control Technology predicts fuel needs according to operating conditions, then delivers the optimum fuel/air mixture to the engine resulting in greater fuel economy.

TECHNOLOGIES

LEAN BURN
The Lean Burn Control System supplies the right 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 gasoline costs are cut thanks to improved fuel economy.

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.
ADVANTAGE:
- More durability compared to belt types of same class.
- Maintenance-free.

SUZUKI WATER DETECTING SYSTEM
It helps protect the engine from water in the fuel using a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.
ADVANTAGE:
- Can avoid water in fuel, which can lead to issues like poor combustion, lower power output and corrosion.

2.59 GEAR RATIO
ADVANTAGE:
- High propulsive efficiency with large diameter propeller.
- Powerful navigation, maintaining propeller rotation even with a larger load.
- Tremendous power to turn large diameter propellers, offering quick acceleration.
