Reel - If Blue has been running the boat for 2 years and the transom wood is dry and the transom doesn't flex . . . I'd have to conclude that the transom crack is just cosmetic and probably a result of the air pockets (voids). Grinding out a narrow 4inch crack and filling it won't effect the structural integrity of the transom.

Epoxy for injecting into the voids => Systems Three 2:1 or west systems will work well. West marine or any other fiberglass supply store will should carry these (both website have a list of resellers). Syringes are available at west marine or pet supply places.

Epoxy fairing compound . . . . Systems Three "Quick Fair".
Goes on like butter.


BR - Just for piece of mind . . . I'd recommend drilling a few holes into the questionable area. If you're going to patch it anyway you can always fill those holes.

Grind out with 50 or 80 grit disc, clean with acetone, quick fair, block sand, acetone, prime and paint.
