Maximising Performance & Fuel Economy

Suzuki engineers have delivered a range of high performance outboards that offer the great fuel economy without sacrificing on performance and employ advanced technologies that Suzuki has pioneered over the last decade. Incorporating the Suzuki Lean Burn System— the same system that has been delivering remarkable fuel economy on most of Suzuki’s outboards starting from the DF9.9B to the flagship DF350A.

The Suzuki Lean Burn System allows the engine to operate on efficient fuel mixture providing significant fuel efficiency while providing the power. These engines also incorporate an O2 Sensor Feedback System that keeps emissions cleaner and more stable, thus reducing impact on the environment. Suzuki outboards are built with decades of experience in the design, development, and manufacture of motorcycle, automobile, and marine engines. Built with the needs of today’s boaters in mind to help you go further, faster, for less.

Suzuki Lean Burn Control System
This system predicts fuel needs according to operating conditions allowing the engine to run on a more efficient fuel mixture through the use of a lean air to fuel ratio. Its benefits are delivered over a wide operating range providing significant improvements in fuel economy from low-speed operation up into the cruising range. In-house testing shows that while cruising, the new DF140A is 14% more economical than its predecessor without sacrificing any of the original DF140’s power.
O2 Sensor Feedback Control System
An O2 Sensor Feedback Control system keeps emissions cleaner and more stable by controlling the air to fuel ratio across each of the engine’s operating ranges, the system helps maintain optimum engine operating efficiency across the engine’s full operating range.
Optimised DOHC 4-Valve Engine
Suzuki engineers have designed an in-line four cylinder engine that delivers high power output, high performance, excellent fuel economy, and efficient operation. With a displacement of 2,044cm3, the in-line four-cylinder block is topped with a high performance 16-valve, dual overhead cam (DOHC) powerhead.
