Suzuki DF40A 40HP 4-Stroke Outboard Motor – Long (20") Shaft, Electric start

About this motor

The Suzuki DF40A is a 40HP four-stroke outboard motor built for boat owners who need dependable power on the water. Fitted with a 3-cylinder, DOHC, water-cooled powerhead displacing 941cc and running a electronic fuel injection (efi) fuel system, this long (20″) shaft outboard is set up with electric start and remote mechanical control, giving you a straightforward, reliable setup whether you’re heading out for a weekend fish or a longer day on the water.

At 108kg, the DF40A is engineered to be light enough to handle on the transom while still delivering the torque and acceleration boaters expect from Suzuki’s four-stroke range. It suits aluminum boats, runabouts and small fishing boats stepping up from a 30HP motor, and is finished in Suzuki Grey to match Suzuki’s current outboard line-up.

Key features:
– DOHC powerhead with four valves per cylinder – the only DOHC engine in the 40-50HP outboard class
– Air intake system optimised for maximum efficiency in the high-rpm range
– 19-amp alternator generates strong charging output even at low idle speeds
– Suzuki’s Easy Start System keeps the starter engaged until the engine fires, for smoother starts
– Suzuki’s anti-corrosion finish bonds directly to the aluminum surface for long-term saltwater protection
