[C320-list] Overheating Engine

[Joseph Aberdale]

Today I started the Yanmar engine in my 2002  C320 and the  
overheating light and alarm went on. I discovered that engine cooling  
water was not being discharged from the hull but you could see the  
discharge of air. Further investigation revealed that water was being  
drawn in through the intake and getting to the engine. Is the likely  
problem the water pump? I recently installed a new impeller and the  
engine ran well after that. How do I determine if the water pump is bad?

Also, I cannot get water to run out of the galley and bathroom  
faucets. The tanks are filled and I can hear the water pump operating  
but do not get any running water. Any thoughts on how I should  
proceed from here?

Thank you very much.
