I've fixed my original horn few times. The location is horrible (anchor locker) and the fix by taking the horns apart and cleaning them lasts only short wile. As you can imagine, few good wave splashes voids all of your efforts quickly. My next attempt was installing electric version (Dual Stainless Steel Trumpets Marine Electric Train Horn for Boats/RV/Trucks 12V Chrome) without an air compressor. I figured if I put it up on the arch, I'll be keeping the tubes as far from the sea water as possible and they should last. Well, this was a good idea but these horns just don't last. I've replaced it at least once, maybe even 2 times already. It's not a hard fix but I checked my last purchase, it was just a little over a year ago. I don't think that replacing the horns every 1.5 years is a solution. Does anyone have recommendations on somewhat reliable horns? I prefer to stick with just electric version, as running a hose would be a PITA project. Also, does anyone have any recommendations on how to keep these horns alive? I assume they get corroded inside from the moist air. I don't think sea water is an issue here, as mine is on the radar arch 20' from the water.
