Better add some knees to that transom. The extra weight of a 4 stroke OB on a bracket{leverage} can be very large. The transom was not designed to hold that type of weight The stringers where the engine mounts were located are designed for that chore. Connect the transom and the stringers together with a triangle, and you have a knee, you need 2. Been there done that.
