Main Engine 4-Stroke · Main Engines (4-Stroke)
This marine propulsion engine is designed for high-performance applications, particularly in variable speed and fixed pitch propeller systems. The FPT Industrial C87 (EPA family KFPXN08.7R3A), manufactured from 2019 to 2019, delivers a rated power of 478 kW at 2300 RPM, with a total displacement of 8.7 liters across six cylinders. The engine is turbocharged and features a direct injection (common rail) fuel system, conforming to EPA standards and classified under IMO Category 1. It operates on a 4-stroke compression ignition cycle, suitable for recreational and general cycle duty. Common issues that may arise include fuel-injection problems, lubricating-oil contamination, cooling-system fouling, charge-air restriction, and valve-train wear, all of which can be mitigated through regular maintenance and the use of spare parts such as fuel-system service items, oil and fuel filters, and cooling-system seals. Critical spares should be ordered based on the specific engine serial number, installed emissions package, and vessel redundancy requirements. Service and inspection should focus on monitoring operating trends, including lubricating-oil pressure, coolant temperature, exhaust temperatures, and overall system balance. Regular inspections of filters, coolers, fuel equipment, valve gear, turbocharging equipment, mounts, flexible connections, and safety shutdown devices are essential to ensure reliable and safe operation.

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.
