Marine Specialist Insight: The Suzuki DF15AS3 (MPN DF15AS3) is the gold standard for portable, mechanical reliability. As a Battery-Less Electronic Fuel Injection model, it offers the high-tech benefits of EFI—smooth idling and instant throttle response—while remaining lightweight and independent of a battery system. The "AS3" designation indicates a 15-inch short shaft with Manual Start, making it the perfect lightweight powerhouse for small skiffs, inflatables, and jon boats.
Lightweight Performance with Digital Precision
The Suzuki DF15AS3 (MPN: DF15AS3) is engineered for the boater who needs maximum power in a portable package. This 15 HP four-stroke engine features Suzuki's groundbreaking battery-less EFI system, which ensures easy, one-pull starting even after the engine has been sitting for weeks. By eliminating the need for a heavy starting battery, the DF15AS3 remains highly portable while delivering the fuel efficiency of a much larger engine.
Equipped with the Suzuki Lean Burn Control System, this motor constantly monitors engine performance to provide the most efficient fuel-to-air ratio possible. This results in significant fuel savings and a cleaner-running engine. The ergonomic tiller handle includes all essential controls and a twist-grip throttle with tension adjustment, giving the operator total command over the vessel with minimal effort.
