Bring a rubber mallet so you can bang on the transom and see if it is soft, also lift the motor up and lock in place and try lifting it from the prop, there should be no cracking noise or movement.
The metal cap on top of transom is a place for water to get in and has rotted many transoms!!
Ck the lower unit oil for any water, or any metal on the plug magnet. ask if he knows when the water pump was changed?
You know there are floor problems, so we won't go there.
Last the gas tank, is it in the console or below the floor? How old is the gas? Does he know if it has ever been replaced?
$3600 Is way over!! But if all checks out the $1500 would be ok!
Good Luck!
