Not sure about your motor, my 1991 115 merc had same problem, I tried module, 90 dollar mistake, eventually found to be float in oil tank, it contacts sensor and stops floating. This horn has many functions, low oil, oil pump motion sensor(pump failure), overheat. Go to 50 to 1 premix in gas till you figure this out. If your temp sensor is in head check it.
