I bought a Tracker Pro170 very much like your new boat back in 2014. It's been a pleasure to own.
I use it on Lake Champlain, "the sixth Great Lake," between NY and VT. The lake is 120 miles long and the south end, where I'm at, is shallow with a mucky clay bottom and full of weeds. In going on seven years, I've never been stuck in the weeds or mud and have never seen anyone else stuck in the weeds or mud (other than a sailboat with a deep keel who drifted out of a channel in one spot, but it wouldn't have happened with a modified V-hull).
It might ease your mind to carry a push pole, but the trolling motor will get you out of any shallow situation you could to get into. You just may have to lift it a bit as mentioned by Way2slow.
And if it's shallow enough to get stuck on the bottom or in the weeds, remember, as a last resort, you can always get out and push!
Take Jaderose's advice and spend a day or two on the water with an experienced boater to get some extra confidence. Then, get out, catch some bass and have fun with your family!
