Cummins Marine 6LTAA8.9-M300 and Engine Parts
Cummins 6LTAA8.9-M300 marine engine is a 6-cylinder in-line, 8.9-liter four-stroke engine with a 114mm bore and 145mm stroke. It is equipped with a Weifu PW2000 fuel pump and RQV-K governor, along with a turbocharger and Air-Air Intercooler. The prime power at 1800 RPM of DCEC 6LTAA8.9-M300 marine main engine is 300 HP.
Based on standard DCEC marine main engines, Hawks Parts provides both heat exchanger cooling and keel cooling marine main engines.we also offer a complete propulsion system, including the marine engine, gearbox, shaft, and propeller as a complete power system. Hawks Parts provides full life cycle services for all customers, from design to power system supply, installation, commissioning, after-sales service training, spare parts supply, trouble shooting, to overhaul technical support.
All DCEC marine main engines come with a dry type exhaust system, meaning a dry type exhaust manifold and dry type turbocharger. Hawks Parts offers upgrading services for water-cooled exhaust systems, modifying dry type exhaust systems into water-cooled exhaust systems, which are often requested for passenger boat projects.
Advantages of 6LTAA8.9-M300 Marine Engine:
- Advanced design and exquisite manufacturing technology ensure reliability and durability, suitable for high-strength and heavy-duty operations under severe working conditions.
- The integrated oil and water pipeline replaces traditional hoses, eliminating the risk of leakage. Enhanced cooling and lubrication functions effectively prolong the engine’s service life.
- The high-pressure common rail fuel system (HPCR) ensures rapid throttle response at different speeds, better power and fuel economy, and lower noise.
- Adoption of an exhaust gas bypass turbocharger ensures smoother supercharging at low speeds and more stable power output at high speeds.
- The engine back-end power output device (REPTO) can enhance the control ability of remote equipment.
