[C320-list] Raw water pump

[Bruce Stumpp]

Mike, 

I have the same engine and just went through the same dance.  The
experienced advice to me was to have the pump rebuilt rather than buy a new
one.  The guesstimates I was given were $150 to have it rebuilt versus $450
for a new one.  It was picked up late Monday and was ready to go this
afternoon. Cost was $156 including a new cover plate, o-ring and impeller.
Unless you have a crack or some other issue, a rebuild should do it.   Check
around for a Yanmar expert near you.  

No trick to removing the hoses, just back off the clamps and twist off the
hoses.  Caution - do not over tighten the bracket bolts or impeller screws
when you reinstall.    You also may need to prime the pump when you first
start the engine after installation.

Looks like my raw water pump is dripping in the front and needs to be
replaced.  I have the yanmar 3GM30 Japanese engine.  Does anyone know the
make and model number of the pump and the best place to purchase it? Also is
there a trick to removing the two hoses attached to the pump?  I have
replaced the impeller many times but never the pump itself.
