Had irratic frequent beeps from warning buzzer with 97 Merc 60 HP. I discovered that the oil level switch is a two part apparatus with a magnet of some type inside the tank and a small switch device about two inches long which is inserted into the bottom of the tank and it apparently works off the magnet inside the tank when the oil level gets too low. Since the magnet device is a part of the tank and the tank costs sixty + dollars, I bought the $14 switch and I am going to see if that will fix it. If not, I will have to buy the tank also unless someone knows another solution. Anyone had a problem with the magnet inside the tank? If so, how does the thing work and what does it look like? Is there any way to fix it without buying a new tank?
