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.

2-STAGE GEAR REDUCTION

Suzuki Easy Start System

The Suzuki easy start system no longer requires holding the key until the engine start. Now simply turn the key and release and the starter will stay engaged until the engine starts.

The system also features more precise cylinder detection, fuel injection, and ignition control to deliver smoother and improved starts, more efficient combustion, and greater fuel economy making the outboard more environmentally friendly.

LEAN BURN

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.

Self-Adjusting Timing Chain

DUAL ENGINE FLUSH PORTS

Over time, salt, sand, and dirt build up can restrict flow in the cooling system causing damage. To help prevent such buildup, DF100B/90A/80A/70A are equipped with two freshwater flush ports that make flushing the cooling system much easier. With one port located on the port side of the down housing and a second on the front panel, you’ll always have easy access to the flushing system whether the boat is in or out of the water.

Tilt Limit System

Suzuki's Anti Corrosion System

Bonding the finish to the outboard’s alloy surface our specially formulated anti-corrosion finish has long been used as an effective treatment against corrosion and is found on all of our outboards.
