I need help with this issue. <br />I know the engines are in great shape. I keep my boat on the same marina where this Formula is kept. I know the mechanic at the marina and as far as engines they are very well maintained. <br />It is twin 350 mercruisers. <br />What concerns me is the hull of Formula. <br />I opend all areas of the boat and it all looks solid with no traces of rot or water. Bilges are dry and clean. The fiberglass looks like it's a hand layed mat (woven cloth). But it is original with no repair patches. There is no visible cracks or anything like that on the hull (both outside and inside). <br /><br />Do I need a surveyer to check out the boat?<br />Any suggestions are apreciated.<br /><br />Thank you all,<br />Lenny
