Take off the spool. on the frame of the reel you will notice some small screws (depending on the reel there may be only one screw)that are holding a plate on a hex nut. undo those screws carefully. lift the plate off the hex nut. loosen the nut a quarter turn. You'll have to line up the nut so that the plate fits back on it. put the screws back in and you are done. You may have to do it a couple of times before you get the drag right where you want it. Don't blame Ebay or the person who sold it to you. I use my 8/9 on largemouth usually with a 12 pound tippet. I have my drag adjusted pretty darn tight too. The previous owner probably never dreamed of using 5x on it... The reel is probably fine and if you ever want to chase something big with it, you have a reel that can handle it.
