[C320-list] Leaking impeller pump

[Thomas Talling]

Hi,
I am having problems with my raw water pump leaking on my Yanmar diesel.  I have replaced the impeller twice as well as the o ring and gasket and the out going tubing and it is still dripping.  Is anyone aware of a bearing or seal that the impeller shaft sets in that could be in need or replacement and if so how difficult that would be?
