Ten years after starting the four-stroke revolution with its award winning DF60 and DF70 outboards, Suzuki re-invented the category with the new DF70 and DF90. 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 DF90 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.
