HIGH PERFORMANCE DOHC 12-VALVE ENGINE

The DF40A and DF50A are powered by Suzuki’s proven in-line three-cylinder 12-valve engine. This high-performance engine has a displacement of 941cm3 and features a DOHC powerhead—the only DOHC engine used in the 40-50HP outboard class—with four valves per cylinder and an air intake system optimized for maximum efficiency in the high rpm range. When designing this engine, Suzuki engineers also focused on improving mechanical efficiency.

Each component was analyzed and redesigned to reduce mechanical loss to improve efficiency. As an example, 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.

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 from smooth starts, maximum operating efficiency, excellent fuel economy, and reduced emissions.

3 + 3 YEARS RECREATIONAL WARRANTY

All recreational/privately registered Suzuki Outboards come standard with a 3-year / unlimited hours manufacturer’s warranty. Recreational outboards are also eligible for a bonus 3-year Warranty providing that an authorized Suzuki Marine Dealership completes servicing as per the owners’ manual schedule. The Suzuki dealer must use only genuine parts and oils during both manufacturer’s and bonus warranty periods.
