A common solution in a marine environment is to manufacture a metal tube
bent to right shape coupled at both ends with a short length of certified
straight hose using 2 hose clamps on both sides of the coupling hose for
security. That means 8 hose clamps per run. This is the method used on
commercial vessels.

Gentlemen (and ladies if you have any comments):

Does anyone know of any "real world" reasons why automotive-type,
corrugated flexible hoses should not be used to replace unavailable or
ridiculously expensive OEM molded hoses in marine engine cooling
applications, i.e.:

A. On the fresh water (antifreeze) side of a heat exchanger cooled engine?
B. On the sea water (salt water) side of the same cooling system?

Please, folks, I'm asking for VALID reasons why the automotive hoses
should NOT be used, not non-specific comments like: "Well, the XYZ company
must have had SOME reason for not using those hoses."

Your comments, advice, or experience with this will be appreciated!

Thank you,
Ed Greeley
