My 2001 horn was Ongaro. When it died, the new model had slightly different mounting hole spacing. I had two options: Patch old holes and make new or remove the mounting bracket from the original and install it on the new horn assembly. The actual horn units were identical, just the bracket was different. Since the old bracket was in good shape and polished up nicely, I opted to swap brackets.Fishtales said:https://www.amazon.com/Ongaro-Mini-Compact-Twin-Horn/dp/B0000BYPGF/ref=sr_1_5?ie=UTF8&qid=1494628897&sr=8-5&keywords=ongaro+marine+horn
I think this is the exact one.
