I just changed the head gasket on my Force 85hp. I tested it after. Runs great. I replaced the impeller last week. When I tested it though, the water was still not kicking out. I shut it down right away. I took the thermostat out, and now the water shoots out fine. Problem is, I cant get a new one till Monday. It's about 90 deg out right now. Will I damage anything running without one?
