I have a Volvo 2002B, 1985. The temp warning came on after about 1 hours continuous use at 2300rpm. The engine ran fine the day before and the previous yrs. Its raw water cooled. I was still seeing the normal amount of water exiting with the exhaust. I removed the thermostat, assuming it was stuck. This did not solve the issue. Since then I have back flushed the thru-hull intake with a shore water hose, its clear. Checked the water pump impeller, all vanes are attached. I checked that water flow our of the exit on the far side of the thermostat and water is flowing meaning water is circulating in the block. Block temp right next to the sensor reached over 200F. I have lots of water flow and still overheats. Suggestions?
