As mentioned above, I rebuilt my 200 CCP, enclosed the transom and added an Armstrong bracket. It worked out great. The full transom gives a great sense of security offshore, and I gained a ton of fishing room. I relocated my bait well to the leaning post, it on a 246 you’d have the option of building it into the transom cap. It’s great to be able to brace thighs against the transom while putting out baits or fighting fish. The cost for the full transom won’t be much more than rebuilding a cut out. New, a bracket will add 3-4K.
Be sure to post pictures. I look forward to following your rebuild.
