Available for sale New Yanmar 6EY17W Marine Propulsion Engine 1138 HP with affordable price US $58000.00. Only limited stock, so contact us immediately.


This economical engine meets the NOx exhaust emission standards adopted by the International Maritime Organization (IMO). With a displacement of more than 31 liters, large
diameter intake and exhaust valves, and a high pressure ratio turbocharger, and employing a state of the art high-efficiency charge air cooler, the engine displays superior combustion performance over a wide range of conditions.

Features:

Low Emissions in Compliance with IMO Tier 2 Regulations
Yanmar’s proprietary fuel injection pump combines high injection-pressure and an original injection nozzle design to miniaturize spray droplet size, which, when used with an advanced re-entrant combustion chamber design, realizes superior combustion for reduced NOx emissions and improved fuel efficiency. This economical engine meets the NOx exhaust emission standards adopted by the International Maritime Organization (IMO).

Large Displacement with Ample Torque and Power
With a displacement of more than 31 liters, large diameter intake and exhaust valves, and a high pressure ratio turbocharger, and employing a state of the art high-efficiency charge air cooler, the engine displays superior combustion performance over a wide range of conditions. The large capacity of the high-pressure ratio turbocharger means that more than enough air is available for any load. Combining a long stroke with Yanmar’s proprietary fuel injection technology yields stable high torque, even under high-load conditions.

Straightforward daily inspection and onboard maintenance
Side windows on both sides of the cylinder block can be employed to inspect the main bearings or facilitate removal of the pistons. Individual cylinder heads can also be removed to allow access to each cylinder. The engine also employs easy to use cartridge type fuel and lubricant filters.

Ever greater durability and reliability
Core components such as the cylinder block and major moving parts such as the crankshaft are engineered down to the minutest details with functional design, utilizing 3D CAD and FEM analysis. The wear-resistant properties of the specially cast cylinder liner combined with an exotic surface finish on the piston rings ensure that durability and reliability do not suffer, even under extreme high-output and high-torque conditions. In order to achieve even higher output, the engine is outfitted with optimal high-performance accessories to mitigate the heat load of the various parts.


YXH-500L (large reduction ratio marine gear)

With a cast case and utilizing a bushless design, the YXH-500L marine gear provides reliability under heavy loads. Light-weight, yet with transmission capacity suitable for high-output engines, this compact, large reduction ratio marine gear is suitable for installation in tugboats.
Again, a major feature of this bushless construction is that there is no need to separate the marine gear from the engine to remove or install the gear components, with maintenance man-hour savings realized accordingly.
