Boat buying advice

The most important, and most problematic issue with boats of this vintage is transom and stringer deterioration. The transoms and stringers both have wood cores and if water gets into them, they will eventually rot and weaken. The notched transoms (like one in pic) are notorious for allowing water to leak under that aluminum angle molding on inside edge of transom and allow water to penetrate core for years, and once inside core, will never come out entirely. If you find that this transom has been compromised, expect to spend roughly $5,000ish to have someone replace it. I would strongly recommend if you do not know a whole lot about boats, to have a knowledgeable person or paid marine surveyor to thoroughly check it for you.

Yep. Take a rubber hammer and tap the hull and transom to see if you can hear differences. Check for any dark spots or softness.
I'm going to go the other way on this one. For $6.5K and assuming you can talk it down further, you are not into it for a ton. You can get a survey for $500-$1K (maybe more, I have not had one done for 20 years). I'd look for gross defects. Bring someone familiar with boats if you can. Your likely going to be spending some money in the future. It is an older boat. Just don't go into it totally strapped.

A survey should be less than $500 for that size and I encourage one AFTER you take a first look at the boat. If boating is new to you, perhaps you have a friend who has more knowledge that would come along for support. A sea trial is a must at some point too. That hull is not a SeaV2 and the ride will be rougher than later years
First time buyers can be y 'blind' when looking over a vessel and in addition pictures can be misleading.
From the pics, the boat looks clean (maybe too clean). Cushions are shot, wood trim has not been kept up. There are no pictures of the motor well, close up of transom or helm station so it's hard to judge. There is no mention of any electronics.
Moisture in the transom or anywhere else for that mater can be impossible to detect without a professional's help. Some wetness is normal especially for the age of the hull.
So if you like the boat, you can always do a deal with a sales agreement that states the sale is contingent on the results of the survey and sea trial.
Note that if there is a cost to launch and haul the boat for a sea trial, you will probably be on the hook for that even if you decide not to buy. Surveyors usually don't do outboard evals so that can be another cost.
even going forward, make sure there is clear title to the boat AND the trailer.

Check for softness in the deck. Any softness is a negotiating point. Also find out what's the deal with the fuel tank. Is it original? Has it been replaced? If it original its 28 years and probably will need replacing soon, another negotiating point. As other have said the transom also needs to be looked Into. Keep in mind that if you love the boat and plan to keep it you'll be investing 5-8k down the line to have those things professionally redone and we haven't even talked yet about the motor. How many hours? Original power head? Original lower unit?If not and you try to unload in in 4-5 years expect to lose 3k more or less because like us its gna keep aging.

Boat looks nice but keep in mind also that once you own it your either Investing time and money Into it or gna sell as you bought it. if it has issues now you'll have to deal with selling It with these issues. If yout lucky you could find a green horn to flip it to butsomeone who knows boats will chew you up and down n probably offer you allot less than what your gna pay for it. Ita kinda like a double edged knife.

You can always make it contingent upon a survey. Hire one if you find anything fishy.
