Hi Todd, haven't heard from you in a while. So you picked up another boat.
Are the cracks below or above the water line? I haven't seen cracks in this area before may have been caused by a grounding.
My concern is water intrusion, therefore first use a dead blow hammer to test for soft spots in the transom core. If Ok then use a dremel to open them with a tapered flare and use gel coat paste to fill.
