Shopping for a used boat, a couple that we like have extremely low hours on them. One of them is 8 years old and hasn't been out of the slip since delivery!! Another one has not been out of the slip in 2 years. The current owner has never had it out, and doesn't really know much about the actual mechanics of the vessel. They start easy and seem to run fine. What special things should we watch for on boats that have been sitting so much of their lives? I'm guessing impellers could be a problem(?)

I believe marine surveyors will go out on a test drive for an extra fee. Would that be advisable? We plan to boat, not float - as much as we can afford.
