This is the only engine in the 40 hp class to offer DOHC performance, and also the only engine in its class to incorporate a maintenance-free, oil-bathed timing chain, which provides the outboard with increased durability and maintenance free operation. With larger displacements for increased power and performance, Suzuki’s Lean Control System for improved fuel economy and designs that are more compact and lighter in weight than the predecessor, the new DF40A engines also incorporate the Suzuki Troll Mode System.  During the 2011 Miami Boat Show, the Boating Writers of America presented Suzuki Marine with the NMMA Innovation Award for the DF40A/DF50A.

Engineered to deliver fuel efficient operation in a compact and light weight design, the DF50A has utilized many of the advancements that Suzuki has pioneered over the past decade.  This three cylinder DOHC engine is designed with Suzuki’s Lean Burn Control System to deliver high tech performance with efficient operation and top level fuel economy. And as an added bonus, new DF50A engines also incorporate Suzuki Troll Mode System.  During the 2011 Miami Boat Show, the Boating Writers of America presented Suzuki Marine with the NMMA Innovation Award for the DF50A/DF40A.

The New DF50AV is designed with a “High Energy Rotation” lower unit sporting a 2.42:1 gear ration, which enables this new model to use a bigger 14″ propeller – perfect for powering pontoon boats and other large, heavy craft. This mid-range engine is also designed with Lean Burn Fuel Control System, which adjusts the air/fuel mixtrue according to operating conditions. The system significantly improves fuel efficiency across the operating range, from low speeds well up into the cruising range. New DF50AV model is also available with the optional Suzuki Troll Mode System.

Engineered to deliver fuel-efficient operation in a compact and light weight design, the DF60A utilizes many of the advancements that Suzuki has pioneered over the last decade. This three-cylinder engine with a four valve DOHC design is combined with Suzuki’s Lean Burn Control System to deliver high-tech performance with efficient operation and top level fuel economy. New DF60A models also sport the optional Suzuki Troll Mode System.
