>But there may be some on the list who don't realize that the
electrically operated compressors for air horns such as the Kahlenberg
Model D-0A are quite small and easy to hide. And, to my ears, an air
horn sounds more like something appropriate for a serious boat.
Our boat has a pair of air horns operated by a small electric compressor
mounted under the flying bridge consol. I have no idea what kind of
horns they are (there does not seem to be a makers name on them
anywhere). The only "distinguishing marks" on them is that their
insides were originally painted red. They are VERY loud. But they are
operated by a simple compressor hooked to a 12 vdc source with air hose
connections to each horn. No air tanks or anything else. Very easy
installation, and the compressor is quite small, about the size of a
large windshield wiper motor. I wouldn't think installing a setup like
this would be any more difficult that installing a set of electric
horns.
Something a surprising number of people overlook is the wisdom of
mounting horns (either electric or air) so that they point down enough
to let water-- rain, spray, washdown-- run out when the boat is in its
normal running attitude. It may look cooler to mount the horns parallel
with the cabin or flying bridge line, but if water is allowed to sit in
the back of the horns the diaphragm mechanism will eventually fail.
