    Merc 225EFI Alarm

    I am totally frustrated and need some help. Problem began with temp light and beeping horn going off with a temp reading of around 140. Replaced thermostats, temp sensor and water pump. It now changes to an alternating temp and oil light and a beeping horn while running. Temp is around 140 and onboard oil tank is full and oil is being consumed. Replaced the throttle position sensor and on board oil tank. BTW, I have disconnected and reconnected all sensor and gauge wires and could get some lights to go off. Now with the key in the on position and the motor not running the alternating temp and oil light and beeping warning horn comes on after about 15 seconds
