The 6BTA5.9-M150 Marine Propulsion Engine is a high-performance power unit designed for small and medium-sized ships. It adopts an inline 6-cylinder structure, a displacement of 5.9 liters, a maximum power of 150 horsepower (110kW) @2600rpm, and a peak torque of 520N·m@1600rpm. The engine adopts turbocharging and intercooling technology, equipped with an advanced electronic fuel injection system, and the fuel consumption rate is as low as 195g/kWh, meeting the IMO Tier II emission standards. The key components adopt a reinforced design, the crankshaft is made of forged steel, and the cylinder body is specially heat-treated to ensure stable output under harsh working conditions. The standard intelligent monitoring system can monitor key parameters such as oil pressure and water temperature in real time.
Engine performance
Efficient intake and fuel system
Equipped with turbocharging and water-air intercooling devices, it can effectively increase the intake volume, allow the fuel to burn fully, and improve the thermal efficiency of the engine.
Reliable structural design
The cylinder block and cylinder head adopt an integrated design, which greatly reduces the number of parts, about 40% less than similar engines, reduces the probability of failure, and effectively prevents water and oil leakage in the engine.
Domestic and international fishing ports and shipyards of all sizes are very familiar with the 6BTA5.9-M150 engine model, and spare parts are widely available. Even in remote ports, finding parts and performing repairs is not difficult. Routine maintenance cycles are clearly defined; daily filter and oil changes can be performed by ordinary mechanics, eliminating the need for dedicated senior engineers and significantly reducing downtime losses.
The 6BTA5.9-M150 is suitable for 15-25 meter trawlers, small cargo ships, harbor workboats, ferries, patrol boats, and other commercial vessels. It is eligible for CCS ship inspection certification, meeting compliance requirements for inland waterway and near-shore commercial navigation.
Overall, it's not a model that pursues extreme parameters; its strength lies in its maturity and reliability. For ship owners, the biggest fear is being stranded halfway through a voyage. This machine is designed for low failure rates, ease of repair and use, and controllable overall operating costs. Whether for near-shore fishing or short-distance transport, its overall performance has been very stable over the long term.
