Got tired of replacing whimpy-sounding electric horns once a year when the saltwater/air got to them.

Bought a single trumpet air horn, with the most plastic parts possible, on Amazon for a whopping $35. I actually bought two ----- to have one as a spare.

I can't believe how loud it is compared to my last 12V ongaro electric horn was. I think the length of the trumpet matters a bunch.....

Mounted the little compressor in the helm console - it is a bit loud when running, but so is the horn at that time, so no matter!!

I'll update (if I remember) how long it lasts.........
