A little flotation goes a long way!!
But that said if you made it like that you don't have any water slamming into it and lifting the rear up in ruff water.\
I think it would be a great bracket, But I to would like to see it have a full plate up against the tramsom also for the extra support.
But with that said, if you add the plate to the inside of the transom and leave it like it is, it will be nice and strong!! As the bulk of the stress will be on the transom, and by distributioning the weight from the inside I think it will work great!!
On mine I wanted the inside to use the hole transom for the weight and had a friend make this for me.
There is no way that the bracket is coming off with out the hole transom going with it!!
