    1997 Merc. 40 hp. Turn key on, alarm sounds and stays on. Turn key back between off and start and alarm stops and engin runs fine. Have tested oil float and it changes beeping when empty, so not the low oil sending unit. Disconnected temp sensor and still steady beep. New impeller and plenty of luke warm water pumping out of tell take hole. It has the Quicksilver key switch with switch sealed and horn assembly next to it. Is there a way to test the switch and horn? My thoughts are painting towards a bad switch/horn assembly.
