HDEF175 EFI

The Hidea EF175 is a 175HP four-stroke inline 4-cylinder outboard motor that utilizes advanced electronic fuel injection technology. With a displacement of 2785cc, it is designed specifically for mid to high-end boats, offering powerful performance, low emissions, and an excellent handling experience. As the flagship product of a high-end outboard motor brand in China, the EF175 incorporates numerous cutting-edge mainstream technologies, including dual overhead camshaft (DOHC), 16 valves, electronic throttle body (ECT), independent coil-on-plug ignition (COP), dual-axis second-order balance system, digital control system, and APP intelligent diagnostics, all while meeting EU CE and US EPA emission standards.

Family-style great Appearance: The seamless integration of smooth lines and mechanical aesthetics, with a one-piece design for the top cover, base, and top cowling, showcases a professional and grand image.

New-Generation Electronic Fuel Injection System: A specialized marine fuel injector combined with multi-sensor feedback (intake temperature/pressure, knock sensor, cam/crank position) accurately controls fuel injection and ignition timing for more complete combustion, leading to strong power output that is economical and environmentally friendly. The waterproof ECU (IP67 rating), carbon canister evaporation control, and trolling mode adjustment further enhance reliability and convenience.

Excellent NVH Performance: The dual-axis second-order balance system, precision-weighted piston connecting rod assembly, intelligent adjustment via knock sensors, optimized mounting frame, and reverse exhaust release ensure exceptional smoothness and quiet operation from idle to high speeds.
