Suzuki DF15AES

Call for Price
State-of-the-Art designs make the new DF15A the most technically advanced portable outboard on the market today. This is the world’s first 15 hp outboard motor designed with Lean Burn and Battery-Less Electronic Fuel Injection. The Suzuki EFI system operates Battery-Less, which is an industry first in this horse-power class. The DF15A is a smooth running “Next Generation” four stroke which delivers quick starts, great accelleration, awesome performance and superior fuel economy. Go Lean, Clean and Green, Go Suzuki!

Fuel Efficiency

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 14.7kW (20PS)/11.0kW (15PS) class. And adding Suzuki’s proven Lean Burn Control technology to their design, these outboards deliver remarkable fuel economy and reduced emissions throughout their operating range.

Lean Burn Control System

Suzuki four strokes are rightly famous for their fuel efficiency and technology that lets you go further, for less.

Cleaner, More Efficient Operation

Suzuki utilizes a number of its advanced technologies to deliver cleaner, more efficient operation that conforms to the Recreational Craft Directive (RCD) – Directive 2003/44EC of the European Parliament and of the Council, and has received three-star ratings from the California Air Resources Board (CARB).

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 14 Suzuki models from the DF9.9B up to the flagship DF300A, providing boaters with top-level fuel economy at all operating speeds.

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 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.

Light Weight & Compact

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.


Easy to Use

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.

Easy Start Recoil Starter

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's Anti Corrosion System

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.
