    Have an old dual air horn on wood boat I am restoring. Just the horn, no compressor. Bought biggest Wolo 12 volt compressor (24 psi) they have and does not work. Went to auto shop and hooked up to air hose and horn does work - seemed like at about 28 psi. No info on horn except word "Titan" on top. Have googled Titan air horns with no results.

    Wolo told me if compressor I bought doesnt work would need compressor system for about $400. Cannot believe that this boat (16 foot Grady White) ever had that big of compressor for air horn - no room!

    Any ideas?

    I Don't know anything about the anatomy of air horns. Mine works perfectly with a compressor that can fit into your hand.

    You are assuming it was original equipment. It may have never worked in that installation. Some air horns, like the ones in large trucks, require a large volume of air.

    I probably works on "canned air" which is compressed air in a can (amazingly enough). These are used to power hand held signal horns and a number of other devices. A better setup would be a small 12 VDC compressor feeding a containment tank and a regulator.

    The horn may be disassemblable, if so, take it apart and check the passages, which may be partly blocked. If not, drop in a bucket of solvent for a few days and see if it cleans up.

    Cheaper to replace. with more reliability.

    Ive found that if you need a horn you generally need it badly.

    They sell high volume 12 VDC compressors intended for just this sort of thing. I have one on my Atkins.

    This system is 50 bucks, complete. Compressor, lines, horn button, the works.

    At 16 foot it would be a reasonable argument wether you even need one.

    Electric is fine and I think may even be considerd by some over the top for a 16 footer.

    Sure.... you need a sound device on a 16 footer.

    Even 16 footers operate in the fog ...even 16 footers need to attract attention in an emergency

    I guess. BUT...if I dont have a horn to get your attention when your hauling *** straight at me...then Im going to have to blast you with my rocket flares.

    Not a problem because I have two eyes in the front of my head used solely for navigation and going backwards N stuff.

    2 eyes in the front of you head is generally a first navigation aid and is above all others.

    Don't you know that because Frosty keeps his eyes open and all senses alert while navigating, everyone else does too, theretofore, nobody needs a horn! Because Frosty will never run into anybody, he will never need a horn to keep people from running into him! Because his boat never has breakdowns, breakdowns never happen to anybody! It is so simple, why don't you understand ?????
    Also, if you had your engines in the stern like normal people, that eliminates the need for horns. Frosty can explain, but it is through the miracle of modern science and that is all you really need to know.
