Need a little help from Cobra owners. I've tried to look up value of my boat on NADA Blue Book but have had no success. I have a 2002 Cobra Coosa 216 (21 1/2 foot) duel consoles, 2004 Mercury 225 Optimax 2 stroke. Boat is in good shape and has tandem axle trailer with new tires (less than 800 miles on them) and a spare that has never been on the ground, new stainless steel fenders, new keel guard, new Fulton F2 1600 Lb Winch, 2 new Fulton transom retractable tie downs. Motor Guide 109 lb thrust 36 volt trolling motor with new G-force trolling motor cord. Lowrance HDS 9 gen 2 and Lowrance X102. I'm 86 years old and due to health and age just don't fish any more so I will be selling my boat but just don't know what to ask for it.
