Cummins 6CTA8.3-M188 Marine Engine
Cummins 6CTA8.3-M188 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 BYC PB fuel pump and R801 governor, the engine comes with a turbocharger and Water-Air Intercooler. The prime power at 2328 RPM of the DCEC 6CT8.3-M188 marine main engine is 188 HP.
Based on standard Cummins 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 offers full life cycle services for all our customers, from design to power system supply, installation, commissioning, after-sales service training, spare parts supply, troubleshooting, 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 offers to upgrade services for water-cooled exhaust systems and to modify dry-type exhaust systems into water-cooled exhaust systems, which are often requested by passenger boat projects.
Advantages of 6CTA8.3-M188 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, greatly reducing oil loss, enhancing durability, and extending service life.
