The World’s First portable outboards in class designed with Lean Burn and Battery-less Fuel Injection

State-of-the-art designs make Suzuki’s portable lineup among the most technologically advanced outboards available on the market. The DF20A, 15A and 9.9B hold claim to being the world’s first battery-less electronic fuel injection four-strokes in each of their power classes. Using all-new fuel injection system components designed smaller and lighter than those found in any previous system, Suzuki engineers succeeded in creating the lightest four-stroke in the 20PS & 15PS class.



New Generation Fuel Injection System

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 20PS, 15PS and 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.

Superior Fuel Economy – Suzuki’s Lean Burn Control System

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 a many Suzuki models from the DF9.9B up to the flagship DF350A, providing boaters with top-level fuel economy at all operating speeds.
