If my trolling motor says 24v then does that mean that I have to hook it up to 2 12 volt batteries to get it to work? Seems like a ton of power for a TM....

In my limited knowledge of 'lectricity, (and I am like labhumper in that regards) I would say that the TM would run on the 12 volt, but draw the battery down super fast.

It means you use two 12V batteries wired in series to yield 24V

If you're wondering how to wire two batteries in series... First battery positive to the positive on the motor - then the negative on this battery to the positive on the second battery and the second battery negative to the negative on the motor.
This is referred to as a "series" connection and will double the output voltage of the batteries.

Just out of curiosity, can I even run it as a 12V or will it a) not run at all or b) run with alot less power for less time?

It will likely not run on 12V.
All electric motors, whether AC or DC powered, will have a recommended range of voltage for reliable operation. I would be willing to say, with decent confidence, that under-voltage will be bad for the motor. I know that over-voltage will cause failure.
DC motor speed and/or torque is regulated by the voltage applied (remember the range of voltage that I was talking about earlier), so 12V will likely not power up the motor, but I'd be willing to bet that if you try and leave 12V to the motor, that you're going to burn something up.
AC motor technology is a totally different animal. If you get to talking about AC power, you can forget all you ever knew about DC power....
