30 hp bad alternator?

2015 Etec E30DPSLADF  05441880 2 1/2 years old, 140 hrs on a flyfishng Micro Skiff single battery for start and 12V trolling motor.  I have GPS which displays voltage. All worked flawlessly: run out in morning displayed 14.2V, run, troll, charge all day, voltage varies, but on the run charges up from 12,2-7 to mid 13’s.  On run Home would gradually charge up to high 13V.  Always very stable.  Last three times out, all of a sudden voltage on the run would vary often and quite a bit.  Thought it was battery, put in new battery, last trip on way home voltage varied fro, 12.5 or 12.6 to 13.1, then back and forth. Bad alternator or V regulator?  All accessories on accessory panel. Advice appreciated.
