Mercedes-Benz has produced a range
of petrol, diesel and gas engines and
marinized some models for different
companies like Solé, Yanmar, etc...
hard enough to find some technical
manuals but you will find here,
for example the Mercedes-Benz OM 636
which is a diesel engine produced by
Daimler-Benz from 1948 to 1990 and the
Mercedes OM314, a 4-stroke diesel engine.
