My first guess would be that the mechanic assembled something incorrectly, or left something out, and that same issues persists and is causing the impellers to self destruct.


I'm not sure what you mean by the "cam to depress the blades"? Does the pump assembly match the parts drawing, or is something missing?


A whole new pump might be a good next step. That would also give you something to compare against.


Hopefully someone familiar with this particular pump will chime in. I'm not. Is it an identifiable Jabsco, Johnson, or other pump?
