    I just put a 4 blade aluminum prop on my boat and the performs great but between 1100 and 1300 rpms a slight squeal is coming from my prop. It also does this when coming off plane but not in reverse. The trust washer has been installed and there seems to be no rubbing between the prop and lower unit housing, what is this sound????
