MAN marine engines
We supply spare parts across the MAN marine engine range. MAN rates its marine diesels by duty class, light, medium and heavy, according to how many hours a year they run and how hard they work. Find your engine below, then send us the model and serial number and we'll match the right parts.
Engine range by duty class
MAN classifies each marine engine by how it will be used. As a rough guide: light duty, up to ~1,000 running hours a year, full load no more than ~20% of the time (yachts, leisure); medium duty, up to ~3,000 hours a year, full load up to ~50% of the time (commercial craft in intermittent service); heavy duty, unlimited hours, up to continuous full load (hard-working commercial vessels).
Workboat & commercial engines, medium & heavy duty
The core of what we do. These D-Series engines are built for continuous commercial service and are MAN's current workboat line.
| Engine | Configuration | Displacement | Typical applications |
|---|---|---|---|
| MAN D2676 | Inline-6 | 12.4 L | Ferries, pilot & patrol boats, workboats |
| MAN D2862 | V12 | 24.2 L | Larger workboats and fast commercial craft |
| MAN D2868 | V8 | 16.2 L | Workboats, patrol and fast commercial craft |
Yacht & light-duty engines
MAN's high-speed leisure line. Outputs below are approximate and follow each model's name.
| Engine | Configuration | Output (approx.) | Typical applications |
|---|---|---|---|
| MAN i6-730 / 800 / 850 | Inline-6 | 730-850 hp | Yachts & trawlers up to ~55 ft, sport fishing |
| MAN V8-1000 / 1200 / 1300 | V8, common rail | 1,000-1,300 hp | Fast yachts and sport-fishing boats |
| MAN V12-1400 / 1550 | V12 | 1,400-1,550 hp | Compact high-speed yachts |
| MAN V12-1650 / 1800 | V12 | 1,650-1,800 hp | Long-range cruising, high torque from low rpm |
| MAN V12-1900 | V12 | 1,900 hp (1,397 kW) | Performance yachts |
| MAN V12-2000 | V12 · 24 L | 2,000 hp (1,471 kW) | Performance yachts |
| MAN V12X-2200 | V12 · 30 L | ~2,200 hp | Newest "X" generation, high power-to-weight |
Outputs and displacements are given as a guide for matching parts, confirm exact ratings against your engine's data plate. Send us the model and serial number and we'll confirm fitment.
Legacy MAN D-Series we still supply
Much of our business is keeping older MAN D-Series diesels running long after they have left the current sales line-up. Alongside the engines above, we regularly source parts for earlier D-Series families, including:
- D2866 and D2876, the classic inline-6 workboat engines
- D2842, D2848 and D2840, the earlier V-engine families
- D0824, D0826 and D0836, the smaller inline D08 series
- D3872 and other legacy units, sourced on request
Gensets & auxiliary power
Many of these high-speed D-Series engines also drive marine gensets and auxiliary power sets, running at constant speed, these versions usually carry an LE2xx suffix. We supply parts for the common genset variants:
- D2840, LE201, LE203, LE213
- D2842, LE201, LE203, LE213, LE223
- D2848, LE213
- D2866, LE201, LE203
- D2876, LE201, LE203
- D0826 (e.g. LE40, ~180 hp) and D0836, smaller inline D08 series
If your engine isn't listed, or you're working from a builder variant such as DEMP or Lindenberg, send us the details and we'll identify the right parts.
