In my search for a new to us vessel I found an ideally optioned 390 Dancer It is a 2005 and has 400 fresh water hours on twin 8.1L gas Merc.'s. Seems very high compared to all the boats we have looked at. Price is 15k lower than most w/ 2 x the hours. I have never had a boat w/ greater than 320 hours before. Would I expect this to be prone to maintenance?Opinions please?
