Main Engine 4-Stroke · Main Engines (4-Stroke)
Direct Injection and Turbocharged, the Yanmar KYDXN2.76D4C engine operates with a 4-stroke compression ignition cycle, delivering reliable performance for variable speed propulsion applications with fixed pitch propellers. Designed to meet Category 1 standards under IMO regulations, this engine features a compact displacement of 0.6 liters per cylinder and a total displacement of 2.8 liters, optimized for efficiency and durability. Operating at a rated speed of 3800 RPM and generating 173 kW of power, the KYDXN2.76D4C ensures robust operation with a torque output of 545 Nm. However, operators should be aware of common failures such as fuel-injection issues, lubricating-oil contamination, cooling-system problems, turbocharger restrictions, and valve-train wear that could compromise performance or safety. Regular maintenance checks on critical systems are advised to ensure the longevity and reliability of this powerful engine.

What our service work and the manufacturer documentation say about keeping this model running.
Review operating trends for lubricating-oil pressure, coolant temperature, exhaust temperatures, load balance, crankcase condition and abnormal vibration or noise. Inspect filters, coolers, fuel equipment, valve gear, turbocharging equipment, mounts, flexible connections and safety shutdown devices in accordance with the installed configuration. Check for fuel, oil, coolant and exhaust leakage and verify that protective alarms and shutdowns are functional. A surveyor will normally look for evidence of disciplined maintenance, clean machinery spaces, leak control, intact guards and reliable safety functions. Use the engine serial number and manufacturer documentation for all exact wear limits, adjustment values and overhaul criteria.
Useful onboard spares typically include fuel-system service items, lubricating-oil and fuel filters, cooling-system seals, belts where fitted, valve-train consumables, injector-related service parts, sensors and common gaskets or O-rings. Critical spares should be selected against the exact engine serial number, installed emissions package and vessel redundancy; refer to the manufacturer parts documentation before ordering.
