Drill it, put bolt with washers on both sides of transom, coat with 5200, tighten nut, let it cure for 24 and you're done.
You can weld a patch, but if the welder gets the metal too hot, your problems will expand. A guys hit on of our pontoons with the mudboat prop and I fixed it like above with a 3"x3" drilled patch. This was the season after Katrina, its still holding.
