Symptom - Over heating, and no water coming from pee tube (what I call it)
took the lower unit off and inspected the water pump and found it to be perfectly fine.
The key was still in place and not boogered up, the impeller was fine and not boogered up.
Took a thermostat out and found the area behind the 'stat to be bone dry.
re-installed and a bit of water was coming out of the pee tube, like it usually does before the 'stats open up. Stopped the engine to do something and restarted and no water came out of the pee tube this time.
removed the lower unit one more time looked at the impeller again and all seems fine.
tomorrow I will reinstall and leave the 'stats out to see if water is getting up there.
Is it possible for a water pump to be bad even though it looks fine and doesn't slip past the key?
thanks
Chris
