Ten years after starting the four-stroke revolution with its award winning DF60 and DF70 outboards, Suzuki is re-inventing the category with the new DF70A and DF90A. 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. They also feature Suzuki's proven offset drive shaft which, used in combination with a newly designed powerhead, contributes to making the DF90A the smallest and lightest four-stroke outboard in its class. This compact, lightweight design also makes any of these outboards ideal for use on a wide range of boat types.
A REVOLUTION IN INNOVATION
Twelve years after starting the four-stroke revolution with its award-winning DF70 and DF60 outboards, Suzuki is reinventing the category again with the DF90A. The first of Suzuki’s new generation four-strokes, the DF90A is a showcase of advancements and achievements such as digital sequential electronic fuel injection, a powerful 2.59:1final drive ratio, zero-maintenance self-adjusting time chain and don’t forget the Suzuki Lean Burn Control System. New DF90A models also sport the optional Suzuki Troll Mode System.
​
OVERWHELMINGLY LIGHT, LIGHTEST IN CLASS
L:157kg, the lightest weight in XXkW (100ps). (SUZUKI internal research)
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 XXkW (100ps). (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.
SUZUKI TROLL MODE SYSTEM (OPTIONAL EQUIPMENT)
EXPLANATION
​
A system that can move the boat at a constant speed.
​
ADVANTAGE
​
-
Boat can be moved at a constant speed without operating the throttle.
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.
