I always had a nice steady stream of water out the overflow opening (p-hole) but now it just spits and is quite hot. The cylinder head also gets extremely hot.
I pulled the water pump which appears to be in normal condition with no obvious signs of wear.
I changed the head gasket and there was no carbon and water passageways were clean (compression is 115 in each).
Could a crack or break in either the exhaust cover and/or exhaust cover gasket disrupt the water flow perhaps forcing hot water to travel backwards within the cooling system? Perhaps this explains the minimal (spitting hot) p-hole water.
The motor is a 1983 15hp.
