Good afternoon from Scotland
I have recently ordered and received an impeller kit from Marine Engine . com which I have fitted today and I am frustrated that the water is still not circulating when the engine is running. I removed the bottom end and fitted a hose to the engine tube and removed the thermostat cover and water flowed unimpeded through this route. I sat the lower end in a tank of water and manually turned the shaft which resulted in water flowing up through the plastic outflow from the impeller proving that the new impeller was working yet when all is bolted together there is nothing coming up through the thermostat housing which is baffling.
I noticed that the thermostat was missing from the housing indicating that a previous owner had been having problems presumably with overheating.
Can anyone advise how best to proceed or what to check next please.
Best regards
