Product catalog summary
Overview
Suzuki's DF140A and DF115A outboards are engineered to enhance fuel economy and performance through advanced technologies like the Suzuki Lean Burn System and O2 Sensor Feedback System, which improve fuel efficiency and reduce emissions.

Main Features
The outboards feature a 2,044cm3 DOHC 16-valve high-performance engine, Suzuki Lean Burn Control System, O2 Sensor Feedback Control System, Knock Sensor, Suzuki Water Detecting System, Multi-Point Sequential Electronic Fuel Injection, and optional features like the Suzuki Troll Mode System and Multi Function Tiller Handle.

Suzuki Lean Burn Control System
This system optimizes fuel consumption by predicting fuel needs based on operating conditions, resulting in a 14% improvement in fuel economy compared to previous models.

O2 Sensor Feedback Control System
Ensures cleaner emissions by optimizing the air-to-fuel ratio across all engine operating ranges.

Engine Design and Performance
The DF140A and DF115A boast a high-performance in-line four-cylinder engine with a 16-valve DOHC powerhead, an efficient "4 into 2 into 1" exhaust system, and a two-stage reduction gear for enhanced torque and acceleration.

Additional Technologies
Includes a Knock Sensor for detecting abnormal combustion, Suzuki Water Detecting System to alert operators of water in the fuel, Multi-Point Sequential Electronic Fuel Injection for precise fuel delivery, Trim and Tilt Limit System for protection during tilting, and Suzuki Anti Corrosion Finish for enhanced durability.

Optional Features
The Suzuki Troll Mode System offers finer control over engine speed at low RPMs, and the Multi Function Tiller Handle is ergonomically designed for easier control.

Specifications
The DF140A and DF115A models feature a 4-stroke DOHC 16-valve engine with a displacement of 2,044 cm3, offering a maximum output of 103 kW (140 PS) at 6000 rpm for the DF140A and 84.6 kW (115 PS) at 5500 rpm for the DF115A.

Design and Innovation
The new engine cover design enhances cooling efficiency, while the offset driveshaft improves weight distribution and reduces vibration.

Expert Insights
Suzuki engineers emphasize the integration of technologies like the knock sensor and vapor separator system, which enhance fuel efficiency and reliability.

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...

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...
