[C320-list] Water Pump Repair or Replace Recommendations

[Dennis Harris]

Stephane,

Go to Torresen Marine (www.torresen.com) and click on Yanmar, then "Complete 
Parts Listings by Engine.  My engine is a European model, so engine number 
is 3GM30F-YEU.  The pump assembly is part 128397-42500 if I read it 
correctly and is actually priced at $232.68.  I just talked with Torresen 
and they told that is the complete pump, not just a part.  (There are two 
water pumps listed and the other one was $245).

Hi Dennis,

Where can you find a replacement pump for 245$, here it's in the 700$
range.

Thank,
