MeridexionMitsubishi’s name appears twice in marine engineering: on medium-speed and auxiliary engines, and inside turbochargers fitted to other makers’ engines. The first is an engine parts enquiry; the second is a turbocharger enquiry wearing a different badge.
In practice, the number on the part is rarely the number we end up quoting.
Two separate product lines
Engines
- SU / KU series — medium-speed auxiliary engines.
- SR series — older auxiliary units, more reliant on equivalents.
Turbochargers
- MET series — widely fitted to MAN B&W, Mitsubishi and other two-stroke engines.
- MET-SB / MET-MB — successive generations with different rotor and nozzle ring designs.
Turbocharger parts are covered under turbocharger and air parts.
Why turbocharger identification is separate
A MET turbocharger is identified by its own type and serial number, not by the engine it sits on. The same engine model may be fitted with different turbocharger types depending on build year and rating. Quoting only the engine model guarantees a round of questions.
Put side by side:
| Data needed | Where to find it |
|---|---|
| Turbocharger type | Nameplate on the turbocharger casing |
| Turbocharger serial number | Same nameplate |
| Component position | Turbine side or compressor side |
| Rotor or cartridge requirement | Stated on the enquiry |
Engine parts: what wears
- Cylinder liners, rings and head gaskets
- Fuel injection nozzles and pumps — fuel injection parts
- Cooler bundles and anodes — cooling parts
- Lube oil and fuel filter elements
Sourcing notes
Mitsubishi engine consumables are widely available as equivalents. Turbocharger components are more specialized: nozzle rings and rotor assemblies should be bought from manufacturers with the correct drawings, and balancing reports are required for rotor work.
Order checklist
- For engines: model, serial number, part number
- For turbochargers: turbocharger type and serial number
- Component position and quantity
- Certificate and balancing report requirement
- Required date and destination
For the wider parts picture see marine engine parts.
In short: Experience says: order the consumables with the parts, not after them, and most of the rest is common sense.

People also ask
Are Mitsubishi MET turbocharger parts available as equivalents?
Nozzle rings, bearings and seals are available from specialist manufacturers. Rotor assemblies and cartridges require correct drawings and balancing, and are usually supplied genuine or fully reconditioned.
How do I identify my MET turbocharger?
From the nameplate on the turbocharger casing, which carries the type designation and serial number. The engine model alone is not sufficient.
Do Mitsubishi engine parts interchange with other brands?
No. Even where dimensions appear similar, material and tolerance differ. Parts must be matched to the specific engine model and serial number.
