( Part Type: Ecm ), ( Manufacturer Part Number: 85961063 )
The Mercury Optimax DFI 225 ECM is a state-of-the-art fuel injection system designed to provide superior performance and efficiency for outboard marine applications. This electronic fuel injection system is manufactured by Mercury Marine, a leading innovator in marine propulsion technology.
The Mercury Optimax DFI 225 ECM is a closed-loop system, which means it continuously monitors and adjusts fuel delivery based on engine temperature and load for optimal performance and fuel economy. It features an electronic throttle and shift control capable of precise and responsive maneuvering.
The system is equipped with a 225cc high-pressure fuel pump, which delivers fuel at a rate of up to 71 psi to the injectors. This high-pressure fuel system ensures efficient combustion process and reduces fuel consumption. The injectors are designed to deliver small, multiple injections per cycle, permitting fine atomization and optimal air-fuel mixture for better combustion efficiency.
Additionally, the Mercury Optimax DFI 225 ECM utilizes an intelligent knock sensor that constantly monitors engine knock and adjusts fuel delivery accordingly, eliminating the need for mechanical fuel pressure regulators. This reduces weight and complexity while improving engine reliability and performance.
The DFI system also incorporates an easy-to-install, user-friendly harness with waterproof connectors, which simplifies installation and reduces the risk of wiring damage due to water intrusion.
Overall, the Mercury Optimax DFI 225 ECM is a reliable, efficient, and easy-to-install fuel injection system that delivers better fuel economy, improved performance, and increased engine durability. With its advanced technology, this system sets a new standard for marine fuel systems, making it a popular choice among boat owners and marine enthusiasts.
