First introduced on our DF90A/80A/70A, the Suzuki Lean Burn system is an intelligent system that monitors engine performance and operating conditions to predict fuel needs and deliver a leaner fuel mixture to the engine. The system delivers remarkable improvements in fuel economy over the engine's entire operating range. This system is found on 14 Suzuki models from the DF9.9B up to the flagship DF300A, providing boaters with top-level fuel economy at all operating speeds.

This intelligent fuel management system predicts fuel needs by monitoring engine performance and operating conditions to deliver a leaner fuel mixture to the engine. The result is remarkable improvements in fuel economy.

A new engine cover design provides the direct intake system with a smoother, cooler flow of air boosting engine operating efficiency. This, together with a newly designed air cleaner allows higher power output from a small displacement.



The rotating flywheel helps reduce temperatures inside the engine cover by venting warm air to the outside from the recoil cover, inner air intake, and engine upper cover.

These are the first outboards in their respective classes to offer fuel injection, and the DF20A/15A/9.9B engineering team did an incredible job designing the outboard without adding unneeded bulk or weight. All new components, including the inline high-pressure fuel pump, fuel cooler, vapor separator, fuel injectors, and a new throttle body, were designed as compact and lightweight as possible. The entire system was designed to fit in as little space as possible. The system operates battery-less, which is another industry first in the 14.7kW (20PS), 11.0kW (15PS) and 7.3kW (9.9PS) class. While fuel injection systems normally require battery power to deliver quicker starts, smoother running performance, and more acceleration in all conditions, Suzuki's Battery-Less system does this all without the need of battery power.

The DF20A/15A's lightest in class title is the result of a complete redesign of parts and components, striving to create the smallest and lightest parts possible without compromising integrity. Succeeding in this, our engineers have delivered an outboard that even when configured with a power tilt system still weighs less than the any other outboard in the 4-stroke 14.7kW (20PS) /11.0kW (15PS) class.

Along with better fuel economy, fuel injection also offers easier and more dependable starts in nearly any operating condition or environment. While our carburetor models are some of the finest outboards available, fuel injection gives these outboards even smoother operation with reduced engine vibration.

These outboards are equipped with starters specially designed with very light recoil loads. Combining the easy to pull starter with fuel injection makes starts exceptionally easy for almost everyone.

Suzuki protects the outboard's exterior from harmful corrosion with its own specially formulated anti-corrosion finish. Applying the finish directly to the outboard's aluminum surface, allows maximum bonding of the finish to the surface to increase durability and help protect parts that are constantly exposed to saltwater.

A number of portable models are now available with a power tilt system that provides smooth tilting of the outboard. The system offers greater convenience and improved easier operation. (DF20AT/9.9BT, DF20ATH/15ATH)
