If that's the 17 I'm thinking of it's a great looking boat with the same Step-lift hull as the V20. 2 fishing buddies had them and kept them for years. One had a 115 Evinrude and ran over 40, after 30 years of use it had the same cracks you describe and he landfilled it. I think it could have been saved. Probably was ran too long and too hard with soft stringers.
