[C320-list] Leaking impeller pump

[Jeff Hare]

As others have mentioned, a rebuild is in order.  But, you'll likely also have wear/scoring of the back plate and the forward surface inside the housing as well from grit in the water.  So the rebuild will likely stop leaking if you replace the shaft and seal, but it won't pump as much water as a new pump that doesn't have this wear.

We purchased a new pump for $180 that primes instantly and pumps water like a firehose compared to the old one (which I had installed the pump rebuild kit). So, if you ever have any issues priming after clearing the strainer, don't bother with a rebuild, get a new one for just a few bucks more.

My opinions of course...

Subject: [C320-list] Leaking impeller pump

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?
