Suzuki DF115BTL

Suzuki DF115BTL is a powerful and fuel-efficient 115-hp four-stroke engine featuring a 2.0-liter DOHC block, EFI fuel injection, and Lean Burn control. The high 2.59:1 gear ratio delivers strong torque and good pulling power, while the maintenance-free timing chain enhances reliability. Weighing 186 kg, the engine is a stable and high-performance option for medium-sized and larger boats.

The Suzuki DF115BTL is a powerful and fuel-efficient 115-horsepower four-stroke outboard motor based on Suzuki’s 2.0-liter four-cylinder DOHC engine. EFI fuel injection and Lean Burn control optimize fuel consumption across the entire RPM range, making the engine highly fuel-efficient under both light and heavy loads. The high 2.59:1 gear ratio delivers strong low-end torque and allows for the use of larger propellers, which improves acceleration, carrying capacity, and handling, especially in larger hull models.

The engine’s design is compact and well-balanced, and it weighs just 186 kg, which is light for a four-cylinder engine in this power class. The maintenance-free timing chain operates in an oil bath and ensures a long service life without the need for tensioning. The 40 A charging capacity is more than sufficient for modern electronic devices, fishfinders, and accessories.

Usability is enhanced by electric start, remote control, the Easy Start system, and optional Keyless start and Troll Mode trolling speed control. The RPM range at full throttle is 5000–6000 rpm, providing a good combination of torque and top speed. For private use, the engine comes with a 5-year warranty, underscoring Suzuki’s reliability and durability.

Offset drive shaft

Offset drive shaft

Thanks to the offset drive shaft, we can reduce the size of our outboard motors by shifting the engine’s center of gravity forward, which improves weight distribution, power, and balance while reducing vibration.
Self-adjusting timing chain

Self-adjusting timing chain

A simple, efficient, and maintenance-free timing chain that operates in an oil bath, so it never needs lubrication, and is equipped with a hydraulic tensioner to ensure it is always properly adjusted.
Suzuki Lean Burn control
