Well, under the dash I have a small hornsiren/ that has two wires coming from it a purple and tanred/ and I am wondering what this siren is for as it is not hooked up to anything. The wires are just dead ended.
That is your overheat alarm.
Tells you when the engine gets too hot.
One wire should be hooked up to the "I" terminal on the ignition switch.
The other wire should be connected to the orange or tan wire that runs to the motor temp sensor.
My guess is that someone got creative and disconnected it.
Maybe the sensor is bad, or they rewired the boat when they switched motors.
