I want to thank everyone for your suggestions. The water was indeed high
enough to wet the crank pulley. Although I didn't hear the belt screeching,
that doesn't mean it wasn't. There were enough other sounds to drown it out,
what with blinding rain battering (this is some of that south Texas flooding
that made the news yesterday) and the fan on high. I bet you're all right on
target, and I appreciate your input.
