This past weekend I was had a Westerbeake 46 that kept overheating. Just out of Swan Creek we overheated and had to return to the slip. We thought it was a loose hose at the hot water heater and tighted them. All was well for a while but later in the weeked it started to overheat again. I did not think it was pumping enough water so we checked the strainer and the impeller and all seemed to be fine. After we got home I started to think about the weekend and wondered if the thermostate could be stuck, which is causing the engine to overheat which in turn is causing the coolant to overheat which in turn is causing to relief valve at the hotwater heater to blow. Anybody else have any thoughts?
