Hello,

I have a 1996 Mercury 225 outboard hp motor for my boat. Been having an on-going issue with one of the warning horns that nobody can seem to resolve. When it comes on it beeps continuously like it has a cooling issue but we have changed out so many parts including the new thermometer, water hoses, new computer, sensors. It seems to run ok for a while and then it starts again. Took it to the marine dealer for them to look at it and they could not find anything wrong with it. Any ideas would be appreciated. Thank you
 
Hello,

I have not. Could a bad float be sending a signal and making the warning horn go off? I will look into changing that out. Thank you for the advice, appreciate it.
