"Anybody know what issues there are in leaving a motor sit without oil? Had the oil out of the boat for about a week and wondered if that was not a good thing to do."
Whatever sufaces that were immersed with oil a week ago still had a light film of same on them over the past week, so those components were never really "without" oil, even if just a thin film. I lubed my garage door's hinge points 6 months ago with motor oil, and today those areas are still damp.
