Most of the vanes missing suggests something radically wrong. The odd vane might go missing in a season - could this impeller have been otherwise in service so long? Or is another agent at work - perhaps clogged ingress of raw seawater laving the pump to run dry, if intermittently. Needs looking at on a whole system basis, I think.
