Can't say it's NOT major until we know what's under that paint! If it was just one small tight crack in one spot, that's one thing, but to have cracks in 3-4 different areas, it seems like the boat is trying to tell us something!

What does the port side look like? Any cracks like on stbd side or anything going on at the hull/deck joint? Shine is a professional fg guy, so if he's concerned, I wouldn't ignore it. I've heard other professional glass guys say that when they start grinding away glass to do a repair, they often find that damage is much more extensive than they initially thought. That's a very high torque motor you have, and it's not only trying to twist the bracket, the setback creates a 2' or so lever arm to put an additional bending moment into the transom, much more than if the motor was just mounted directly to the transom. If the bracket has a big flotation tub and swim platform like a Hermco, that will spread the motor loads across the entire transom, but if it's only about 1' wide with minimal flotation like a Stainless Marine bracket, that not only concentrates the load, the lever arm created by the setback multiplies the bending moment on the transom!

I stole that picture from the reed smith post in For Sale section but it came out much smaller than I expected. Here's a link to his pictures which include a couple of good shots on a B/M SF cap/inner liner.
