Ten years after starting the four-stroke revolution with its award winning DF60 and DF70 outboards, Suzuki re-invented the category with the new DF75A. As the first of Suzuki's new generation four-strokes, they are a showcase of advancements and achievements – such as digital sequential electronic fuel injection, a powerful 2.59:1 final drive ratio, and a zero-maintenance self-adjusting timing chain – that Suzuki has pioneered over the last ten years.

A NEW STANDARD IN FOUR-STROKE FROM SUZUKI

Suzuki has once again reinvented the category again with the DF75A. Suzuki’s new generation of four-strokes, the DF75A, showcases advancements and achievements – like digital sequential electronic fuel injection, a powerful 2.59:1 final drive ratio, and a zero-maintenance self-adjusting time chain. All of this comes in addition to Suzuki’s Lean Burn Control System, and newer models also sport the optional Suzuki Troll Mode System.

​

OVERWHELMINGLY LIGHT, LIGHTEST IN CLASS

  • 346lbs., the lightest weight in under 100hp class. (SUZUKI internal research)

COMPACT

  • Offset drive shaft for compact body.

THE LARGEST REDUCTION GEAR RATIO

  • 2.59:1, the greatest reduction gear ratio under 100hp class. (SUZUKI internal research)

OFFSET DRIVESHAFT

 

EXPLANATION

​

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

 

EXPLANATION

​

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.

LEAN BURN

 

EXPLANATION

​

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 costs can be saved thanks to improved fuel economy.

SELF-ADJUSTING TIMING CHAIN

 

EXPLANATION

​

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

  • Higher durability compared to belt types.

  • Maintenance-free.

TILT LIMIT SYSTEM

 

EXPLANATION

​

A tilt limit system prevents the outboard from tilting beyond a certain angle.

​

ADVANTAGE

  • Prevents damage to the boat or outboard due to excessive outboard tilting.
