DF20AS3
Marine Specialist Insight: The Suzuki DF20AS3 (MPN DF20AS3) is the lightest 20 HP outboard in its class, achieved through Suzuki's revolutionary Battery-Less Electronic Fuel Injection. By delivering the power of a 20 HP engine in a portable, manual-start package, it provides the perfect solution for small fishing boats and skiffs that require maximum thrust without the weight of a battery system. This is a true "plug-and-play" powerhouse with industry-leading fuel economy.
Portability Meets Professional Fuel Injection
The Suzuki DF20AS3 (MPN: DF20AS3) is engineered for the boater who refuses to compromise on power or portability. This 20 HP four-stroke engine features a 327cc twin-cylinder powerhead that utilizes Suzuki's high-tech EFI system to ensure instant, one-pull starts in any weather conditions. Because it is battery-less, the weight is kept to an absolute minimum, making it one of the easiest 20 HP motors to handle and mount on a 15-inch short shaft transom.
This model features the Suzuki Lean Burn Control System, which intelligently adjusts the fuel-to-air mixture based on real-time engine data. This results in incredibly smooth idling and a significant reduction in fuel consumption at cruising speeds. The ergonomic tiller handle is designed for comfort during long days on the water, featuring a large shift lever and integrated throttle tensioner for precise control.
