Chris:

Systems on power boats are exactly the same as sail, with one exception. Some power boats have the room for a full size vertical refrigerator/freezer but I have never seen one on a sailboat. Sailboats have fiberglass top opening ice boxes that usually have had a cooling system added. Both sail and power use DC cooling, although the power boat ones usually also work on AC.

One reason that power boats have more problems with their engines is that some have high hp, turbocharged and after cooled engines and these are more complex so they have more problems. If you were to compare a Perkins 4-154 on a sailboat and a displacement hull power boat, I suspect they would do the same.
