I had bought an 06 Q4 SF earlier this summer from a private party. The guy I bought it from bought it brand new last year and still has a warranty. I'm having problems with the boat porpoising. My local dealer isn't very helpful and gives me attitude everytime I call him to take a look at it, been trying to for 2 months now. My father in-law, who has worked for lund boats for 30 years noticed some cracking where the transom meets the hull and says there is a slight hook in the hull and maybe somebody had tried to fix it before. maybe the factory or whoever. But anyway, I'm wondering how to go about getting this problem resolved since my local dealer isn't very helpful at all. What should I expect to get done? The previous owner said it's been like that ever since he had it too, which lets me believe maybe something was done at the factory? Any input on what I should do or expect would be helpful. Thanx.
