Might want to look at minnkotas 3X steering models. You can reverse the head in seconds and they don't require you to move much when turning. I'd get a 70 + lb and definitely 24v. You'll never say "I shoulda bought a smaller trolling motor".Have fun!
brichards44-- I'd buy it if it was a great deal in good shape. 62 lbs of thrust will be plenty for a 16 footer to give you a break from the oars, however, I wouldn't count on it for getting you too far up the "creek". I run Motorguide 60" 36 volt 101lb thrust on an 18' boat, and that's overkill, but sure nice getting around in a hurry when you want to. As far as brand to go with, you won't find any better that Motorguide or Minnkota. It's a 50/50 split in my opinion. I've owned them both, but prefer the foot control and smoothness of the Motorguides steering. Minnkota offers much better remote motors though.
