It should sound a constant horn for either an overheat or an oiling problem-like an oil restriction. What model do you have? Is your GT a crossflow-they made both a looper and crossflow 150 this year?

It's a crossflow. You could temporarily disconnect the two overheat senders in each head. If the horn still goes off, then it is the oil system. If not, you are either overheating, or you have a bad overheat sensor.
