Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** and thanks for your question.
Yes, unfortunately the controller is at fault. I don't have access to the question you are referring to, you would need to copy the question URL and paste it here. Also make sure the cowl inlet and blower case is clear of any debris that would restrict airflow and only run the heat on full hot when necessary. The controller is cooled by blower airflow. Overheating is the main cause of failure.
