Lots of closed freshwater systems. Lot's of radiators? Not. My boat is a
closed freshwater system and uses a heat exchanger. Is a radiator in some
respects that it cools the engine coolant. But the heat exchanger is used
on all these closed cooling systems. Do a google search and enlighten
yourself on on these freshwater engines are cooled.

Sometimes, I really get shocked, reading some of this crap ! and the
responses are just as dumb !!!
People, call some dealers, look at the boats for sale on the web. There
are
plenty of inboards, with closed
fresh water systems, using radiators. I think even if you used yahoo, and
typed closed fresh water system , and the word boat, you'll get plenty
of
pages to go too. Don't respond now, and say you knew that, because your
posts, certainly do not say a word about them, and those systems, are not
new, used since maybe the 60's
God Bless, the dumb and the stupid because they know,not what they say.

Noisy. Very noisy. On an airboat, no-one cares about the fan, it's
lost in the hurricane. On a boat, you don't want to start the engine
for a little assist at the dock and suddenly have to put up with
yelling over a cooling fan.

Many boaters crave tranquility on the water, not hi speed thrills.

Besides, a rad and fan weigh more than a piece of hose and a
waterpump you already need, especially since, if you don't want hot
exhaust pipes in the bedroom, you want additional cooling capacity
to cool the pipes.

It's cheaper and less hassle to use raw water or even a keel cooler.

With a rad, you also have a blast of hot air to contend with.
