[C320-list] Yanmar Problem

[wflowe3 at aim.com]

 Get 3 or 4' of plastic tubing the same id as the intake hose. Get a plastic barb that fits into both the intake hose and the tubing. Connect the two together and secure with hose clamps. Set the bucket of water in the cockpit and run the tubing through the portlight to the bucket. Fill the tube/hose with water--stick the end in the bucket and start the engine unless there is a major blockage or the pump isn't working, the extra head from the elevated bucket should push out airlocks and get the pump primed and running.  This is the method I use to get anitfreeze into the system for winterizing.

Thanks for your responses. I inspected the impeller after I started  
it.  There are no missing vanes or cracks. There are no air leaks in  
the line.  I think water is getting to the pump because the large  
clear plastic filter in the line is filled with water. The boat is on  
the hard. I have the water intake hose disconnected from the thru  
hull and in a pail of water about six inches higher than the pump.
