Suzuki DF20ATHL 20 HP EFI 4-Stroke Outboard Motor

The Suzuki DF20ATHL combines Suzuki's battery-less Electronic Fuel Injection (EFI), electric start, tiller steering, and Power Trim & Tilt into one of the most versatile portable outboards in Suzuki's lineup. Featuring a 20-inch long shaft and smooth, fuel-efficient performance, the DF20ATHL is an excellent choice for aluminum fishing boats, utility boats, inflatables, skiffs, small pontoons, and other applications requiring the convenience of Power Trim & Tilt.

Suzuki's battery-less EFI system delivers dependable starting, exceptional fuel economy, crisp throttle response, and reduced maintenance compared to traditional carbureted outboards. The electric-start system provides convenient push-button starting, while the tiller handle offers precise control directly from the stern. Power Trim & Tilt allows you to easily adjust the engine angle while underway for improved performance, shallow-water operation, and effortless trailering.
