FAQ

Q1: Is this engine a direct bolt-in replacement for my existing NT855 engine?
A: This engine is designed as a direct OEM replacement for standard NTA855 and NT855 applications. However, due to variations in marine gear couplings, PTOs, and accessory mounts, we recommend comparing your existing engine’s dimensions (L*W*H: 1592x79x1364 mm) and mounting pattern with this unit. Contact our technical team with your engine serial number for specific fitment confirmation.

Q2: What is the difference between the NTA855 (300hp) and NT855 (220hp) versions?
A: The primary difference is the power output. The NTA855 is a turbocharged and aftercooled version, providing 300hp. The NT855 is a turbocharged (non-aftercooled) version, providing 220hp. Both share the same block and many internal components, but the aftercooling system on the NTA855 allows for higher power density. Please ensure you select the correct power rating for your application.

Q3: What is the recommended maintenance schedule for this engine?
A: Following standard guidelines, we recommend an oil and filter change every 250 operating hours. The fuel filter and water separator should be serviced every 500 hours. Valve lash adjustment and injector service are recommended every 2000 hours. Always consult the official NT855/NTA855 operator’s manual for your specific engine serial number for the most accurate maintenance intervals.
