Multi-Point Sequential Electronic Fuel Injection The DF140A and DF115A are the Suzuki's first fourcylinder 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. Multi-Point Sequential Electronic Fuel Injection is Suzuki’s sophisticated fuel injection system found on Suzuki outboards from the DF40A to DF 350A. The system uses a 32-bit computer in the electronic control unit to monitor vital...

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...

Jun Itoh In charge of Engine Design. Suzuki Employee for 17 years. When we started development of the DF100A/115A/140A our goal was to retain the best characteristics of original DF140 and focus on more fuel efficiency and reliability. To achieve our goal we incorporated a number of new technologies into these outboards. These are the first four-cylinder outboards to incorporate a knock sensor. To determine the sensor placement, we carried out a series of tests to find the proper position for mounting the sensor on the engine. Adding the knock sensor to the engine allows for finer control...
