HDEF150 EFI: The flagship electronic fuel-injected model combining robust power and cutting-edge technology. The HIDEA HDEF150 is a 150 hp, 4-cylinder, inline, four-stroke outboard motor featuring advanced electronic fuel injection technology. With a generous 2785 cc displacement, it is specifically designed for mid-range and high-end boats, delivering outstanding performance, low emissions, and a premium riding experience. As the brand's flagship model, the HDEF150 incorporates numerous advanced technologies, including a 16-valve DOHC engine, electronic throttle control (ECT), direct coil ignition (COP), a dual-axis second-order balancer for exceptionally smooth operation, and intelligent diagnostics via a mobile app. It is also fully compliant with both EC (Europe) and EPA (USA) emissions standards.

Description

Family-style design and modern aesthetic

The harmonious integration of flowing lines and mechanical aesthetics, combined with a one-piece design for the top cover, base and cowling, gives this engine a professional and imposing image on the water.

Next generation electronic fuel injection (EFI) system

A specialized marine fuel injector, combined with multi-sensor feedback (intake temperature/pressure, knock sensor, camshaft/crankshaft position), precisely controls injection and ignition timing for more complete combustion. This ensures robust power while remaining economical and environmentally friendly. The waterproof ECU (IP67 rating), the carbon filter (canister) evaporation control system, and the trolling mode setting further enhance its reliability and ease of use.

Excellent acoustic and vibration (NVH) performance

The dual-axis second-order balancing system, the precision-weighed connecting rod-piston assembly, the intelligent knock sensor adjustment, the optimized mounting support frame and the inverted exhaust system ensure exceptional smoothness and quiet operation from idle to the highest RPMs.

Powerful alternator and security alarm system

A high-capacity alternator offers excellent charging capacity (enough to power several onboard electronic devices simultaneously), while the ECU continuously monitors key parameters and emits audible and visual alarms to ensure your safety.

Intelligent digital control

Communication between the ECM and ECU enables intelligent control for single, twin, or multiple engine configurations. The HD digital display integrates graphics and an NMEA2000 digital network interface for ultra-precise operations related to starting, throttle control, gear selection, preheating, and docking maneuvers.

Mobile diagnostics via app

The dedicated mobile application allows for easy diagnosis of the engine condition and simple updates to the ECU programs.

Leading corrosion resistance

Industrial-grade, multi-layer protective coatings guarantee exceptional resistance to seawater corrosion, ensuring long-term durability of all structures.

Product features:

Electronic throttle body (ECT)

The electronic throttle body precisely regulates the volume of air admitted according to navigation commands, engine load and navigation conditions, enabling smooth starts, instant acceleration and stable deceleration, while effectively reducing fuel consumption and emissions.

Coil-on-Plug Ignition (COP):

Each cylinder has independent ignition, with ignition energy directly applied to the spark plug for stronger ignition and more thorough combustion, enhancing power output and system reliability.

Digital Control System:

The digital control system enables high-speed communication between the ECM and ECU, facilitating intelligent collaboration for single, dual, or multiple engines. It integrates functions like startup, throttle control, gear selection, synchronization, diagnostics, and alarms, making operation more intuitive and safer.

Dual-Axis Second-Order Balance System (NVH Optimization):

The dual-axis second-order balance system, along with precisely weighted moving parts to within 1g, effectively reducing engine vibration and noise, resulting in a smoother and quieter sailing experience.

APP Intelligent Diagnostic System:

Through a mobile app, users can monitor engine status, diagnose faults, and upgrade ECU programs, simplifying maintenance and providing peace of mind during use.
