I have a 2000 4.3 litre that is overheating because it is not pulling in cooling water from the lake. I replaced the impeller and thermostat before realizing raw water was not coming in. I pulled all the hoses at the thermostat and poured water into them to verify there is no clogged passageways. I pulled the outdrive and did not see any obvious problems. The only thing I have not done is put in a new water tube seal.
It sounds like I have an air leak in the raw water passageway. Is there a chance that a worn water tube seal would cause this much trouble?
