I understand for earlier threads that the MAN 1200hp LE406, 1200 HP is the very last development of their fully mechanical engines, produced for decades and widely regarded as very reliable. From earlier threads I also read that the engine needs a rebuilt at some point (running hours), depending on usage. What would be the typiscope of such a rebuild? My engines now have close to 3 000 hours on them (sits in a Princess/Viking 20M from 1999), most of these at low loads.
