Indmar monsoon 350 5.7 overheating. I can see no suction and no water through clear plastic flush pro valve. New raw water pump w new impeller, checked oil cooler little inlet screen, fresh water flush cap on back screwed on tight, inlet grill and hose is clear coming from bottom of hull. Thermostat looked a little stiff so i removed for troubleshooting. Not getting any water flow. Fresh water hose connected seems to work fine and engine stays cool... but probably working because of hose water pressure.
