What is the difference between a Marine 350 and a car 350?

A car engine typically only uses a portion of its horsepower to maintain a decent speed on the road. On the other hand, a marine engine is essentially at full throttle all the time just to move it through the water, so it has to be pretty heavy duty to keep up.
