The Hidea HDEF115 EFI is a robust and refined 4-stroke outboard that delivers high performance with cutting-edge EFI technology. Powered by a 4-cylinder engine, this 115HP model is engineered for reliability, fuel efficiency, and smooth operation.

Featuring a Programmed Electronic Fuel Injection (EFI) system with a DELPHI ECU, the HDEF115 provides quick starts, precise throttle response, and optimal fuel economy across all speeds. Its Reverse Exhaust Relief system ensures quieter operation by directing exhaust through the propeller hub underwater.

The HDEF115 EFI also includes an advanced Engine Alert System to monitor critical functions like temperature and oil pressure, enhancing long-term durability. With its power thrust design and high gear ratio, it delivers impressive forward and reverse thrust, boosting control and maneuverability.

Ideal for recreational and light commercial use, the HDEF115 is NMEA2000 compatible for easy integration with marine electronics—performance, efficiency, and innovation in one powerful package.

Hidea HDEF115 features
