Unfortunately the above maybe an over simplification of the real difference between an automobile's gasoline engine
and a sailboat's marine
The gas engine requires electricity to ignite the gasoline/air mixture - The diesel engine requires only compression
to ignite the diesel/air mixture.
And probably the greatest source of problems in a marine
diesel engine is it's need for raw water
to cool it. To do this it will utilize a heat exchanger
with its own water
pump which in turn cools the engine's fresh water
The Automobile's cooling
system usually relies simply on a radiator and a fan.
Probably the closest one might get to a marine engine in an automobile would be a light pickup truck with an diesel engine around 2,500 cc.
