I don't think you have anything to worry about mechanically. Notably, there is no rust residue seeping from the gasket between the risers and exhaust manifolds. Had that been present, the gasket is compromised and while not a big deal necessarily in and of itself, the fact that there is no residue means it was either addressed promptly, or the integrity of the exhaust/water jackets are in tact.
The gauge cracking is typical of that era, eventually. Those gauges are at times hard to come by and spendy, but perfect pass would fix one of them. The dash shows minor sunburn.
I note seperation of the vinyl at the seams in the rear. Not terrible yet, but should be on your radar. Notably, the trunk vinyl has been replaced. For a 22 year old Florida boat, not uncommon, but it was not likely a garaged boat.
I am somewhat concerned by the port carpet near the hull. That "pull" up could be indicative of it "sinking" on the trailer/lift. In other words, bilge filled with water with the plug in. Slight waterline at bottom of observer seat "could" confirm the same. Alternator is also particularly pitted, suggestive of storage with the clamshell closed, or that it "sunk" on the trailer. Although, there is evidence of usage of a "BIMP ring" (those in central florida will know the reference), which is good.
That said, that's a smoking price for what is a fantastic boat. At absolute worst, a new 350 costs less than $5,000 last time I needed one. Still a great price.
