   Payton,
Before you condemn the sensor, I suggest using an IR temperature gun to check exactly what the temp is. Aim it next to the sensor. Also, for checking proper cooling, I suggest getting it off the garden hose. The pressure from the hose will give you false results. Stick the suction hose in a bucket of water instead and use the garden hose to fill the bucket. Also, you may be sucking air but a water leak won't show up even with the engine shut down.  Double check all your hose connections and the gasket on the sea strainer.

	Hi Guys, I changed and the water impeller and cleaned the water strainer before firing the boat up with a fake-a-lake and let it idle for about 5-10min before the overheating light came on and the boat shut off.. Temp was no higher than 160 on the gauge. I let it cool down for 30min and now the boat dies around 140F with the overheating light coming on. I'm not sure what to do. I took out the thermostat and tested it in a pot of water - seem to open around 150F and be fully open at 160F which I believe is in line with needing to have the 160 T-stat on the TBI motor. I plan on putting a new one in anyway. I checked to make sure the impeller was installed correctly and also made sure the strainer is installed correctly and both check out. I read that I could have an air leak but I see no signs. it seems to be pumping plenty of water still. Maybe I need to replace the temp gauge? I'm trying to diagnose. Any help would be appreciated. Thanks
