I found a 2003 Fisher 165 Pro Avenger Sport walk-thru for sale. Any opinions on these? The asking price is $6500 with a 50hp Merc. Only know problems are the tilt/trim switch on the throttle isn't working(motor switch works) and some rub marks on one side from the dock. It was also used in the bay but the motor looks very clean along with the bottom of the boat. <br /><br />Any tips or idea's as far as cost, what to look for, quality, etc.?
