A PERFECTLY TAILORED FIT. The New DF60AV is designed with a “High Energy Rotation” lower unit, sporting a 2.42:1 gear ratio, enabling this new model to use a bigger 14 in. propeller – perfect for powering pontoon boats and other large, heavy crafts. This mid-range engine is also designed with the Lean Burn Fuel Control System, which adjusts the air/fuel mixture, specific to your vessel’s operating conditions. This system significantly improves fuel efficiency, from low speeds well into the cruising range. New DF60AV models are also available with the optional Suzuki Troll Mode System.
