[C320-list] Broken Impellar

[P & B Sheerin]

Interesting Jane & Ken. Just opened my water pump cover to find one of the 
vanes missing. Must have occurred some time ago. No evidence anywhere, 
still with exhaust flow good. The impeller otherwise looked in quite good 
nic after 160hrs.

Kurt,
I have had three vanes missing (don't ask) without any problems on my 
Perkins engine. I was able to locate them in the heat exchanger and discard 
them. My vanes were small enough to not block too much water flow. OBUOY

I opened up the water pump to replace the impellar and noticed one of the 
vanes is missing. I could not get to the heat exchanger to open it and look 
for the missing vane. What is the best case scenario and the worst case 
scenario if I don't do anything?

I have the 3YM-30 Yanmar engine. Does anyone know how to remove the 
alternator to get to the front of the heat exchanger?

Thanks,

Kurt
