Great help thanks so much guys. How do you know when it fails? Just high temp due to no circulation?
My 2nd project is installing a temp gauge. Currently I have a coolant temp gauge that is not working. Should I replace it or install an oil gauge? If so, where is the oil port sender will get into?

This was a cost savings for C&C. Those systems use the Yanmar belt driven water pump as a fresh water pump mounted low on the engine and have an added Jabsco belt drive pump for raw water system mounted higher up. Both use rubber impellers (not great). Factory Yanmar 3GMF and 3HMF use metal impellers on the circulation side and the pump mounts up at the thermostat. The rubber impellers are not ideal as a circulation pump as the coolant temperatures are significantly higher than experienced on the raw water side. I’ve also experienced bearing failures with the Yanmar pump which costs upwards of $600.
