I have one of these from a HMS Queen Mary (I not II) lifeboat. Anyone know of any schematics or technical details? I got it running a few years ago, but want more info if available. We sleeved the cylindars, got good compression and cleaned the injectors to get it operating, but now I want to recondition to orignial condition. It has been sitting for over 10 years since I ran it! It is water cooled and has a bilge pump, fuel filter wipers, as well as a reduction gear built in. Could not find a serial number, or model number on the engine. Weighs about 800 lbs.
