The NLDE-3 is a compact, high-torque engine optimized for small marine vessels. Specification NLDE-3 (380J-3) Configuration In-line, vertical, water-cooled, 4-stroke Number of Cylinders Rated Output 20.6 kW at 2800 rpm Combustion System Direct injection Starting Method Electric (optional spring/mechanical starter) Standard Gearbox Weight Approx. 200 kg Engine Component Breakdown
The NLDE‑3 is not sold as a standalone engine; it is always part of a complete lifeboat or rescue boat package. Primary applications include:
Counter-clockwise (looking at the flywheel). 2. Main Structure & Fuel System A significant portion of the manual is dedicated to
The NLDE-3 is a vertical, water-cooled, four-stroke engine featuring direct injection. Key specifications include:
The NLDE‑3 is a water‑cooled, inboard diesel engine primarily manufactured for use in marine survival craft. It is best known as the standard powerplant for the VIKING Norsafe Midget‑530 MKII rescue boat, where it drives a conventional propeller through a ZF12M gearbox (a 1:1 transmission specially designed for lifeboat applications) . The engine is also fitted to larger SOLAS lifeboats, such as the 8.56‑meter enclosed lifeboat series and the GES30/NLDE‑3 lifeboat . Every NLDE‑3 unit meets the rigorous International Maritime Organization (IMO) standards and the Life‑Saving Appliance (LSA) Code, ensuring that it can start and run reliably even after prolonged periods of inactivity.
Check battery voltage (12 VDC), ensure glow plugs are activating, check fuel supply, and ensure the emergency stop is not engaged. Fuel System : Often linked to fuel air-locks
VIKING’s technical support department can supply either a digital copy (PDF) or a printed manual. They may also provide access to a secure owner’s portal where all documentation for your specific lifeboat can be downloaded.
Always clear codes after repair, perform a “diesel adaptation drive” (10 minutes at 2,500 RPM, light load, then full throttle 3 times), then re-scan.
Avoid generic “NLDE-3 service manual” from unknown sources – they often mix data from different engines.
