@vtjc: WOW! Thanks!!! Very kind of you! I appreciate the advice. The boat I've been looking at does not have ZO, just PP. It is crazy how much difference in pricing exists. I think I'll hold out for a boat with ZO, if I can find the right boat. If a boat has been well maintained, in excellent condition, is there a total hours that would scare you away? Seems like a pain to convert to ZO on the pre 2007 boats, probably not worth it. Thanks again!
