I am getting hairline cracks on my 2002 Pro175 cockpit and can't figure out why. I have always kept it wiped down with marine vinyl protector when I do my seats and although the boat is stored outdoors, it has always been double covered (boat cover and a silver tarp over the cover). I sent an email to G3 last week, but have not heard from them. Anyone experience this with this model year? I am the original owner. I am concerned about the structural integrity.
