We recently acquired a large inventory of overstock items from a boat manufacturer. These products originally arrived in the manufacturer's packaging; however, in some cases, the original packaging may not be suitable for shipping and has been replaced with new packaging. Lower unit does have some minor box rash from previous storage (Please review photos).
