Cummins 6CTAA8.3-M260 Marine Engine

Cummins 6CTAA8.3-M260 marine main engine is a 6-cylinder in-line, 8.3-liter four-stroke engine with a 114mm bore and 135mm stroke. Equipped with a Weifu PW fuel pump and RQV-K governor, the engine comes with a turbocharger and Air-Air Intercooler. The prime power at 2134 RPM of the DCEC 6CTAA8.3-M260 marine main engine is 260HP.

Based on standard DCEC marine main engines, Hawks Parts provides both heat exchanger cooling and keel cooling marine main engines. We also provide a complete propulsion system, including the marine engine, gearbox, shaft, and propeller, as a complete power system. Hawks Parts full life cycle services for all our customers, from design to power system supply, installation, commissioning, after-sales service training, spare parts supply, trouble shooting, to overhaul technical support.

All Cummins marine main engines come with a dry-type exhaust system, which includes a dry type exhaust manifold and dry type turbocharger. Hawks Parts provides upgrading services for water-cooled exhaust systems, modifying dry type exhaust systems into water-cooled exhaust systems, which are often requested by passenger boat projects.

Advantages of 6CTAA8.3-M260 Marine Engine:

  • Advanced design and exquisite manufacturing technology ensure reliability and durability, suitable for high-strength and heavy-duty operations under severe working conditions.
  • Utilizes a high-pressure fuel pump for more complete combustion under high fuel injection pressure, resulting in less energy loss, strong power, excellent fuel adaptability, and lower emissions.
  • Features a Holset supercharger with an integral wastegate valve, offering low-speed responsiveness and strong power.
  • Integral cylinder design reduces the number of parts by about 25% compared to similar products, resulting in a lower failure rate and more convenient maintenance.
  • The cylinder liner adopts a platform mesh honing design and a corrosion-resistant high-nickel cast iron piston, which greatly reduces oil loss, enhances durability, and has a longer service life.
