Looks beautiful BG love the look of those duallies. I don't think you will have any problems with the level while underway but you will have to address the problem if you are going to fish in a good chop or swells drifting, and if there is a lot of boat traffic.
As a temp fix what you can do is purchase a pair of the toggle type garber plug that you use for the outside of the boat and stick them in the scupper holes on the inside for when you are just normal condition fishing etc. to keep the cockpit dry. Just remember to pull them out if the water gets tough and you stand a chance of getting MJ'D.
Other than that you are going to be a$$ heavy and will have to relocate weight forward to balance the boat. It is the balance that you have altered with the bracket and the engine size. It can be done I believe and I am sure you will sort it out.
You should be very proud you did a good job my friend ;)
