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 optimised for maximum efficiency in the high rpm range.
When designing this engine, Suzuki engineers also focused on improving mechanical efficiency. Each component was analysed and redesigned to reduce mechanical loss in order 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.

Self-Adjusting Timing Chain
Self-Adjusting Timing ChainThe timing chain runs in an oil-bath, so it never needs lubricating, and is equipped with an automatic hydraulic tensioner, so it remains properly adjusted at all times. Simple, effective and maintenance-free.
Large Capacity 19A Alternator
Large Capacity 19A AlternatorThe DF40A, DF50A, DF60A and DF60AV are all 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.

Suzuki’s Anti Corrosion System
Suzuki’s Anti Corrosion SystemSuzuki protects its outboards with an anti-corrosion finish specially developed by Suzuki. Applied directly to the aluminium surface it maximises the bond between the finish and the surface, increasing the protection and durability of parts that are constantly exposed to saltwater.
