PRODUCT INFORMATION

Maximizing Fuel Economy, Maximizing Performance Suzuki engineers have delivered a pair of outboards that offer great fuel economy without sacrificing on performance and employ advanced technologies that Suzuki has pioneered over the last decade. The DF140A and DF115A incorporate the Suzuki Lean Burn System—the same system that has been delivering remarkable fuel economy on Suzuki’s award winning flagship, the DF300AP, as well as the DF20A/15A and DF40A through DF90A outboards. The Suzuki Lean Burn System allows the engine to operate on a leaner, more efficient fuel mixture providing significant...

■ 2,044cm3 DOHC 16-valve High Performance Engine ■ Suzuki Lean Burn Control System ■ 02 Sensor Feedback Control System ■ Suzuki Water Detecting System ■ Multi-Point Sequential Electronic Fuel Injection ■ Suzuki Troll Mode System (Optional) ■ Multi Function Tiller Handle (DF115A Optional) Suzuki Lean Burn Control System Recognizing a need for more fuel-efficient outboards, Suzuki developed and introduced its innovative Suzuki Lean Burn Control System on the DF90A/70A outboards, which received great acclaim from boaters and the media alike. The system predicts fuel needs according to operating...

Suzuki has a long history of designing and manufacturing engines for motorcycle, automobile, and marine use. Drawing upon this unrivaled experience 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 124.7 cu.in. (2,044cm3), the in-line four-cylinder block is topped with a high performance 16-valve, dual overhead cam (DOHC) powerhead. Obtaining Maximum Performance employed a two-stage system that provides the required torque without adding unwanted bulk or weight...

Knock Sensor The DF140A and DF115A are Suzuki’s first four-cylinder outboards featuring a knock sensor. Found on some V6 models, this system is used to detect and control abnormal combustion allowing the engine to operate at optimum performance. The system increases engine durability and helps deliver maximum power. Suzuki Water Detecting System Water in the fuel can lead to problems that include poor combustion, lower power output, and corrosion. The Suzuki Water Detecting System is designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert...

Trim and Tilt Limit System The trim and tilt limit system is designed to help protect the boat from damage that can occur when tilting the outboard. A tilt angle sensor performs as both a tilt limit and trim sender and a step-free, continuous type tilt limiter makes installation of the outboard possible on nearly any type of boat. Suzuki Anti Corrosion Finish Suzuki’s Anti Corrosion Finish is specially formulated to increase the durability of the engine and help protect parts of the outboard’s aluminum exterior. This advanced finish is designed for maximum bonding of the finish to the outboard’s...

Suzuki Modular Instrument System (SMIS) SUZUKI MODULAR INSTRUMENT SYSTEM (SMIS) uses an easy to connect and expandable cable system to transmit graphic and numerical data to Multi-Function gauges. This easy to install and set up system can be used with nearly any boat and the DF140A/115A Suzuki outboard. When connected to an *NMEA2000® compatible system, the gauges can display real-time readings from compatible electronic probes and the exclusive SMIS engine interface to monitor engine functions. (Engine Monitor with 4" gauge only) * registered trademark of National Marine Electronics Association...

A word from Suzuki engineers Tomohiko Miyaki Tomohiko Miyaki In charge of Electronic Component Design. Suzuki Employee for 20 years. Our trim sensor integrates the functions of both the trim sender and the tilt limit switch. We also reduced vibrations that occur in the lower trim range to provide greater operating comfort. Placement of the sensors was determined after analyzing strength of the nearby parts. When placing sensors such as the O2 sensor, knock sensor, etc., we looked at operating conditions within the engine room and ran simulations to test proper and reliable function. Knock sensor...
