I guess that you, Limey have got enough experience of looking at boats good enough to see if it's any good or not.
Providing the tubes are in good nick and the hull is sound, everything else can be removed and replaced easy.
Consoles are fairly straight forward to move, and the addition of some nice seating would be good. Place an A frame at the rear to stop your passengers falling off and your nearly home dry
Next thing is the outboard....Get it serviced by a main dealer (better still, get the seller to do it) and really find out what it's like. If you replace it, it'll cost you a little more than the price of the whole outfit for a brand new one and that's not too bad.
$10,000 seems like a real cheap price for this outfit, so go with a Nautical friend for a second opinion and be wary of con-men/something wrong with the rig. Take cash as well, because you can buy it (often getting a better price by waving $'s in their face) and you get to drive it away then and there.
I suspect that if it's a genuin sale then and been on the market for a while, then the layout is what is putting people off.
Good luck mate!
