I have an Onan 9.5 kW genset, and I'm burning thru impellers at the rate of 1/ 75 hours. I'm asking it to lift
about 6 feet (catamaran), through a water
Too high? If so, is there a fix -- an intermediate pump of some sort? A bigger impeller?
I also note that when I install (correctly spiraled) and then re-open an hour later, one or two of the compressed blades are almost always pointed in the "wrong" direction ... I am sure I am installing these correctly, and the problem has occurred with marina installations as well ...
Hmmm ... help!
