How much fuel capacity did you give her? I replaced the two original 75's with identical tanks but out of 3/16" gauge aluminum and added a 105gal 3/16 alum tank in the belly while I had the deck out. A little overkill but I will never have fuel capacity issues.
The only real issue I encountered was that by placing the heavy outboard 30" further aft on the brackett, it upset the fore aft lay at rest. Put 350# lead in the anchor locker which helped and also installed a sump in the rear deck with a rule 2000 on a floatswitch. The sump has a grate over it to keep guts, debris etc, out. I also made some foam plugs for my 2" scuppers to keep water out when she is really heavy. I sometimes put over 2000# fish on ice.
Somehow, I don't think your boat will be as heavy as mine and will not carry all the heavy gear either, so you might be just fine. If you end up having the same issue for some reason....let me know and I'll take some detailed photos of my sump setup.
Your brackett setup looks great. Nice job on the refit.
Here's a shot kind of showing the sump setup. Best I can do for now...Jo
