HDEF50

HDEF50 EFI - The top of the mid-range from China's innovation leader for four-stroke outboards

As a leading brand, Hidea has the responsibility to drive technology in the Chinese outboard industry. With the development of the new 4-cylinder HDEF50 EFI, we are expanding our range of four-stroke engines in the medium power range.

Electronic fuel injection system (EFI)

✅ The 4-cylinder engine with DELPHI's programmed EFI system controls the ignition timing precisely, ensuring optimum performance, spontaneous throttle response and efficient fuel utilization.

Fast start

✅ The EFI system automatically adjusts the air/fuel mixture, enabling a quick, easy start and rapid warm-up of the engine. Simply turn the key - and off you go!

Quiet operation

✅ Thanks to the Reverse Exhaust Relief System, the exhaust gas is directed through the propeller into the water, which makes the engine run much more quietly.

Motor protection system

✅ The Engine Alert System continuously monitors important engine functions and warns of overheating, low oil pressure and other critical conditions - for greater safety and a longer engine life.

Power-Thrust-Design

✅ With a higher gear ratio, the HDEF50 EFI provides exceptional forward and reverse thrust - for better maneuverability and higher performance.

Efficient fuel utilization

✅ The Multi-Point Fuel Injection System works together with long intake manifolds and automatically adjusts the air-fuel mixture to the speed and load. This maximizes performance across the entire speed range and saves up to 20 % fuel at cruising speed.

Areas of application:

✅ Fishing
✅ Water sports
✅ Leisure time
