Why no radiators in boats?
 

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.

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.

There are indeed many boats with closed cooling systems, but I have never
seen one with a radiator and fan.

Most use a heat exchanger linked with sea water.

Perhaps you could supply us with the specific link to a radiator/fan cooled
inboard?

Sandy and All,
I'd like to thank everyone for their comments. I sort of figured that
excess heat and getting cool air to a radiator would be a hindrance. I
definitely think a closed system is the way to go even in fresh water,
though I probably wouldn't pass on a boat with regular open cooling system
since I do boat in fresh water. In salt water I'd only buy a closed system.

Since external water used in cooling engines causes a lot of problems,
why
hasn't a car type radiator system with fan ever been used?
Paul


In layman's terms, an inboard engine in a planing hull works very hard (as
compared to a automobile engine) because the inboard engine is always in
the
automotive equivalent of first gear. The water in a radiator is hot,
whereas the raw water (from a lake, river or ocean) used for cooling an
inboard engine is at the very most less than half as hot as radiator
coolant, and most of the time the raw water is around one-third the temp
it
would be if it were radiator coolant, so an inboard engine must run cooler
with raw water than the same engine would run if it had a radiator.

A fan and radiator on the end of the engine would take up extra room,
about
1 foot or so, in a small inboard runabout, room which really is not
available.

Also, a mechanically driven fan which cools a radiator takes some
horsepower
from an engine. An inboard engine does not lose this small amount of its
horsepower.

Steve,
Heck of a conversion job, how does it workout? Is overheating a problem?
What's the temperature in the engine compartment?

Thanks, but I really can't take the credit, just responding to the request
for links. Look for Poleka's posts at
http://www.boatered.com/forum/forum.asp?FORUM_ID=3 for more details.

Finally, where are you gonna mount that radiator? Take your yacht club
pennants on the front of the bow off, and line up three automotive
radiators
across there, with fans . . . and black radiator hose running for and aft?

Technically, a heat exchanger is not a radiator.

A radiator transfers the heat of coolant to the atmosphere. IOW, it "radiates"
heat.

A heat exchanger, as the term is commonly applied, transfers heat between
liquids.

Thats a lame argument. Think about it.
