H-10 Series – H380, H410G, H350G5, H380G6

H-10 Series Engine

Two versions of this modern, electronically controlled design delivers 380 and 170 kg/m of torque and 410PS and 174 kg/m of torque from the 10 litre in-line 6 cylinder engine. The H engine is rated for Heavy Duty and takes Hyundai Seasall into a new dimension with the ability to serve the professional and commercial markets.

The designs optimize fuel injection and intake porting to improve combustion performance, particularly low-temperature combustion stability though lean air-fuel rationing.

This ensures that we satisfy the world’s strictest exhaust emission standards while providing the smooth, quiet and efficient power for which Hyundai SeasAll is becoming known.


The broad flat torque curve proves Hyundai Seasall’s diesel development capabilities are world-class and beats the performance of competitions comparable models. Economy is assured by the state-of-the-art fuel management system featuring Electronic Unit Injectors (EUI). The electronic engine control systems makes the engine lighter,quieter and more fuel efficient with excellent compact dimensions.


At the core of Hyundai Seasall’s Advanced diesel technology is a focus on stability, performance, fuel efficiency and reliability: key elements which make their engines world class.

Cast iron cylinder block

The unique one-piece CGI (Compacted Graphite Iron) cylinder head makes the engine lighter and quieter than conventional engines for more comfort onboard. Plus, longevity is assured with close to double the fatigue life of grey iron and aluminium

Powertrain technology

Hyundai Powertrain Technology, already proven in a full range of modern diesel engines, now brings this exceptional performance and reliability to the marine market.
