Hi Dennis. Did that. No apparent problem downstream. No water is getting to heat exchanger which is first thing downstream of pump. Dave

Focus your investigation downstream of the pump. Disconnect the hose from the discharge of the pump or the inlet to the exhaust elbow. Start the engine and observe if you have flow.
--Dennis C. Touche' 35-1 #83 Mandeville, LA Eliminated many possibilities yesterday. Pump shaft turning fine. Replaced impeller. Still not pumping water. Has anyone had a priming problem? My current hypothesis is that either the pump is not self priming or the seacock is partially plugged limiting flow. Water comes into raw water strainer with lid off but no idea if it is normal rate or not. Dave
