What is this car ???

At one time I worked on commercial fishing boats and saw these engines put to service as generators on 75' vessels. Beauty of the MB 4-cyl diesel is that it was very quiet in operation, unlike the Perkins diesel that made so much racket it would shake the entire boat.

I think the 1.8 litre is actually a very well mannered, highly efficient and practically portable little engine that has probably seen service in all sorts of functions like pumping water, powering winches and operating light heavy equipment

Hello,
Do not want to hijack this thread, but are you refering to the ohv OM636 diesel or the ohc OM621?
IIRC, the 621 was just a ohc head on the 636 bottom end, with 3 bearing crank and all until it was redesigned as the OM615.
Have a good week.
