Suzuki DF15A state-of-the-art designs make the DF15A and the DF20A among the most technologically advanced portable outboards anywhere. The DF15A and DF120A are the world’s first marine outboards in the 15hp and 20hp classes equipped with a battery-less fuel injection system that offers quick, easy starts and cleaner, fuel efficient operation. Suzuki engineers took a bold approach in building all-new fuel injection system components that are smaller and lighter than those found in previous systems. By adding the proven Lean Burn Control technology to their design, these outboards deliver remarkable fuel economy and reduced emissions throughout their operating range.
