Looking good!!
I have a similar boat, 2015 Xpress XP200 SC with a Yamaha 115 (same camo). I love it so far and like yourself have made several modifications to mine.
Mine came with 3 bases up front and only 1 in the rear so I bought a Dub-L-Seat because I could not add anymore in the rear, that is something you may want to look into if you don't want to add the other bases. Mine also has a rod box on the left side that goes up into the deck.
I will agree with you about the trolling motor mount, I have not found a way to reach the front of the boat with the design. My fiancee` can get inside the deck (can't get my fat butt in the hatch!) but can't reach up far enough with the way the deck rises on the nose. Some course thread self tappers may do the job or a really small kid? lol

I am really pleased with how they ride for a tin boat even in rough water, kinda wishing I had went with a 150 and hydraulic steering.
Looking good and thanks for sharing the pics.
