Will newer or bigger batteries increase the power of a trolling motor or just increase the battery life?

Just battery run time and life. Power is the same.
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
So switching from a Group 27 to a Group 29 or 31 wouldn't have an affect on the output/power of the TM, just the battery life?
Battery life or Run time. Power the same.

Yes, however the discharge voltage curve of a lead acid is very non-linear.....if you are waiting until the TM noticeably slows down ("starting to die"), the battery is being overly discharged.
The power (top speed) of the trolling motor throughout the "safe discharge" of the battery is reasonably constant (the flatter part of the voltage curve) .
When I first put in in the mornings I can run on 4 or 5 and cover water at a good speed but after running the TM for about 3 hours or so I end up having to crank it up to 7 or 8 to get the same type of speed out of the TM. Batteries are 4 year old Everstarts that stay on the charger when not in use.
With a larger capacity battery, you will have more power longer. This is with a typical lead-acid or AGM battery. A Lithium, Nickel-Cadmium, or other specialized cell delivers its voltage, under load, at a constant value until failure. A Lead Acid has a downward slope to its voltage as its reserve is diminished.
A newer battery will be more efficient. If you got the money, buy new and big.
