Based on your previous posts,I know your looking at Sceptre models. I have been advised that some of late 80's Sceptre's had a "Hook" in the hull caused by using a retired mold. Check the Port side between the chines at the transom. Lay a 4' straight edge fore & aft. You will see it if pronounced. The Potter era hulls are consistant in their construction. The later years have had many surprises
BTW: Any hull can have or have had problems. Judging the quality of a hull only by it's year is foolish. "Clean Looking" does not always mean "Structural and Mechanically Sound" Get a moisture meter and hire a good marine surveyor & engine Mechanic and don't be afraid to stick your nose where it doesn't belong. Most cosmetics can be repaired
