OK, here's the situation. When I run my boat (20' Aquasport) if I hit some waves, or while I'm on plane, or if I corner sharply the hoern starts to chirp. Not loudly mind you, but it chirps. Once I have the boat back level, the chirping stops after a bit. I just bought a new horn thinking it was defective ($95.00 later) and now it still chirps. The engine (95 Evinrude Vindicator 200) doesn't show any signs of overheating and runs well. I had a small crack in the fuel line a week ago and fixed that so it can't be sensing fuel smell and I don't smell fuel in the cabin. So, is there really a problem that I can't find, or is the problem electrical, or perhaps a bad sensor that the horn is attached to?
