With the DF40A Suzuki's engineers have combined a high performance DOHC (dual overhead cam) engine with Suzuki's Lean Burn Control System to create an outboard that delivers superior power and performance along with top-level fuel economy. Suzuki's Lean Burn Control System monitors engine performance and operating conditions to predict fuel needs and deliver a leaner fuel mixture to the engine, providing great improvements in fuel economy from low speed operation up into the cruising range. A new oil pump design also improves the efficiency of the internal oil flow, better lubricating the moving parts while using less energy.

This DF40A is one of only two outboards in it's class to incorporate a timing chain. The chain is self adjusting and maintenance free, providing years of reliable service. This outboard is also fitted with a powerful 19A alternator, which generates approximately 11.5A even with the engine running at a low 1,000 rpm.
