DF300

At 4.0 litres, this new 24-valve engine offers the largest displacement of any V6 outboards ever made at an amazing 274kg.

The low-end torque provides the ultimate in acceleration and power and the aggressively designed new lower unit reduces drag by an amazing 18 percent.

The new DF300 is also the first Suzuki to feature Suzuki Precision Control - an advanced fly-by-wire shift/throttle control box designed for single, dual helm installation, with single, twin or triple engine rigging.

This new electronic control provides many performance advantages over conventional systems, including smoother, more decisive shifting and quicker throttle response.

This innovative new outboard boasts other design features popularised on other advanced Suzuki 4-strokes, including computer controlled multi-point electronic fuel injection for optimum performance and a self-adjusting, oil bathed timing chain.
