2025 Suzuki Marine DF25A EFI S Manual

A four-stroke of genius.

As the world’s first 25 HP outboard motor designed with Lean Burn and Battery-Less Electronic Fuel Injection, the DF25A EFI knows a little something about exceeding expectations. An ultra-light, smooth running “Next Generation” portable four-stroke outboard, it delivers quick starts, great acceleration, unparalleled performance and superior fuel economy.

Features may include:

Lighter and stronger.

True to our reputation for building lightweight marine outboard motors, the DF25A EFI is not only packed with some of our finest technology, but also the lightest outboard available in the 18.4kW (25PS) four-stroke outboard class.

Be good to the environment and your wallet.

Our Lean Burn 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: less emissions and remarkably improved fuel economy.

Off center. On the ball.

By positioning the crankshaft slightly off center of the cylinder, we’ve reduced the lateral pressure against the cylinder wall as the piston moves up and down, so you can enjoy smoother piston movement and improved operating efficiency.

Fueled by innovation.

Our Battery-Less Electronic Fuel Injection System fits perfectly in the Suzuki DF25A EFI without adding any unnecessary bulk or weight. What’s more? Despite being battery-less, it offers more acceleration, quicker starts and smoother operation in any condition.
