Only comparable thing for sale is this and it does look significantly better with no bottom paint indication of mooring but is a lot more expensive and maybe sold?

Has he asked if the stingers or transom was ever worked on replaced?
I would try grabbing the leg of the engine lifting it up and down to see if there is significant flex in the transom. Then toe press the whole floor to see if there are soft spots.
If he really wants a boat and the above doesn’t scare him off or assure him the work has been done, then it may be worth hauling it over on the ferry to Blackline. Maybe before he does that get an agreement on price in place minus any estimated work to be done? With blackline they do good work but it adds up quickly so it maybe worth it to get a good deal and then do the work himself.
Get some pictures of the batteries/electrical. That to me is a big indication of one of the expensive systems that can go wrong.
Definitely let him know he could spend 15k on the hull and 15k on the motor and still have a 10k boat in 12 months time.
Price is a little high due to it being moobut it’s supply and demand. I think at 12k it would a lot closer to a fair deal. But if trailer is in good shape, stingers and transom are solid then 15k for a hardtop with a nice cockpit cover might not be the worst deal with a 300 hour engine.
also based on my friend owning a similar boat for 10 months, who is he, who is he taking out and how often? My friend got two foot new footitus and spent another 60k because he wanted something new and reliable.
if your friend drives a 95 regular cab pickup this would be a good boat to go with it, if you get what I’m putting down
