gasolinerecreationalcommercial

Overview
The Hidea HDEF150 EFI is a 150 HP four-stroke, inline 4-cylinder outboard engine (2785 cc) engineered for mid- to high-end recreational and commercial boats. It integrates advanced electronic fuel injection and modern engine controls to deliver strong torque, low emissions and refined onboard behaviour while meeting EU CE and US EPA standards.

Appearance
The one-piece top cover, base and cowling combine smooth lines with mechanical detailing to present a professional, family-style exterior suited to leisure and workboats.

New-Generation Electronic Fuel Injection System
A marine-specific fuel injector with multi-sensor feedback (intake temperature/pressure, knock sensor, cam/crank position) precisely controls fuel delivery and ignition timing for improved combustion efficiency. The system includes a waterproof ECU (IP67), carbon canister evaporation control and adjustable trolling mode for reliable, economical operation.

Excellent NVH Performance
Dual-axis second-order balance, precision-mass pistons and connecting rods, knock-sensor adaptive tuning, optimized mounting frame and reverse-exhaust layout reduce vibration and noise for smooth operation across idle to high RPM.

Powerful Charging and Alarm System
A high-capacity generator supports multiple onboard devices. The ECU continuously monitors key engine parameters and provides audible and visual alarms for operational safety and preventive maintenance.

Intelligent Digital Control
The ECM and ECU enable smart control for single, twin or multi-engine installations. The integrated HD digital display supports instrumentation and a NMEA2000 interface for precise management of start, throttle, gear selection, warm-up and docking procedures.

APP Mobile Diagnostics
Mobile application connectivity allows quick engine-state diagnostics and ECU firmware updates for field convenience.

Industry-Leading Corrosion Resistance
Multi-layer protective coatings and marine-grade materials ensure enhanced resistance to seawater corrosion for long service life.
