I have a 1993 Starcraft SFM 170 powered with a 1993 Mercury 115 outboard. Recently, the alarm sounded continuously when the ignition was on. I replaced the overheat sending unit, and the alarm stopped for about 1/2 day of fishing. It is now on continuously. The engine is not overheating. I am thinking I may have a faulty alarm control. I have located the actual alarm horn under the dash, but cannot locate the alarm control unit. Can someone help?
