Suzuki DF15ATHL 15 HP EFI 4-Stroke High Thrust Outboard Motor

The Suzuki DF15ATHL is purpose-built for boaters who need maximum low-speed thrust, exceptional maneuverability, and effortless trim adjustment. Featuring a 20-inch long shaft, electric start, power trim, tiller steering, and Suzuki's High Thrust lower unit with a 4-blade aluminum propeller, the DF15ATHL is ideal for heavy boats, pontoons, sailboats, work boats, and kicker motor applications.

Suzuki's battery-less Electronic Fuel Injection (EFI) system delivers dependable starting, excellent fuel economy, crisp throttle response, and smooth operation without the maintenance associated with carbureted outboards. Combined with power trim, the DF15ATHL allows you to adjust engine trim while underway for improved performance, handling, and shallow-water operation.

The included High Thrust 4-blade aluminum propeller provides increased low-speed pushing power and improved control under heavy loads, making this one of Suzuki's most versatile portable outboards.
