Delivering Superior Fuel Efficiency and High Performance
With a larger displacement of 941cc for increased power and performance, Suzuki's Lean Control System for improved fuel economy and incorporating designs that are more compact and lighter in weight than the predecessor, the New Generation Suzuki Suzuki DF50A offers industry-first features to provide industry leading performance and reliability. During the 2011 Miami Boat Show, the Boating Writers of America presented Suzuki Marine with the NMMA Innovation Award for the Suzuki Suzuki DF50A's innovations which remains some of the leading features in its class.
MULTI-POINT SEQUENTIAL ELECTRONIC FUEL INJECTION
Suzuki pioneered the use of multi-point sequential electronic fuel injection in four-stroke outboards. This advanced, time-tested system gathers operating data from a series of sensors located in key areas on the engine, processes the data and calculates the optimum amount of fuel and air needed for the engine—all in real time. Boaters benefit with smooth starts, maximum operating efficiency, excellent fuel economy, and reduced emissions.
Outboard Class Exclusive DOHC Performance
This is the only engine in the 40 hp class to offer DOHC performance, with four valves per cylinder, and an air intake system optimized for maximum efficiency in the high rpm range.
LARGE CAPACITY 19A ALTERNATOR
The DF40A is equipped with a powerful 19A alternator that generates approximately 11.5A even with the engine running at a low 1,000 rpm. Under normal circumstances that’s enough power to keep an assortment of marine electronics operating in most situations.
Maintenance-Free Oil-Bathed Timing Chain
The only engine in its class to incorporate a maintenance-free, self adjusting, oil-bathed timing chain to provide increased durability and maintenance free operation. A new oil pump design makes internal oil flow more efficient, keeping moving parts better lubricated while using less energy. The combined reduction in mechanical loss throughout the engine contributes to better fuel economy.
Suzuki's Inovations Have Lead The NEW DF50 To Outperform The Original DF50, Making the 2015 DF50 A Leader In The Class.
MAXIMIZING FUEL ECONOMY AND PERFORMANCE
Suzuki's Lean Burn Control Technology optimises the fuel-to-air mixture throughout the engine's operating range to help maximise performance and fuel economy.
