Hyde Kanoe fiberglass repair opinions

[Cherokee-Runabout]

Hey everyone, so I'm back with yet another handful of questions about the best way to tackle this repair. The top of the transom on my Hyde Kanoe has cracked. I really would like to open it up and reinforce transom with some fresh ply as there is a bit of flex but don't really want to try to remove entire cap. Should I just cut a section out from hull ( white portion ) and rebuild transom that way and glass over the cap (red portion) or would there be any benefit to leaving it as two separate pieces? Or should I just repair crack in cap, keep transom as is and just plan on running trolling motor/ under 3 hp outboard? I don't think that the transom is rotten, just not sure that it was beefy enough to handle my four-stroke 6 hp. I've searched a little bit but it's difficult to find topics about this. The cap just seems to be glued on with no mechanical fasteners. Thanks for any and all input!!

Also the crack doesn't permeate into white portion of transom, just the red cap.

I'd want to know for sure if the transom has any rot - if I was gonna be doing anything there, I'd want to do all that was needed

Do you think it'd just be best to cut out from the outside with jig saw/ oscillating tool and then just glass it all together? I can't really get to inside because of design unless I remove cap which I'm not a hundred percent sure I can do. Maybe with a heat gun...

I agree about the rot and I'm just trying to come up with the best way to go about it.
