  Ok, I'll bite.
  
  First go buy a 45 lb. marine battery then figure out a way to securely
mount it in the rear compartment, making sure that it cannot come loose
during rolls.  You'll need to drill a hole through the deck for the leads
from the trolling motor and you'll want to seal this hole quite well since
you want to eliminate the possibility of water intrusion.  Now install a
one-way vent in the rear compartment to vent any gases created by the
battery.  You're done with the easy part.  You just created a hi-tech
version of a Canadian Ballast Rock (TM)  The next thing is the motor
mount....

  Since most trolling motors are designed for use with boats with MUCH more
freeboard than a kayak you'll quickly notice that a standard length shaft
will place the prop far too deep into the water.  Given that trying to
convince the trolling motor manufacturer to develop an
Ultra-Super-Short-Shaft model targeted at kayakers will be akin to trying to
fly by running down a hill flapping your arms you may find that it is easier
to have someone fabricate a motor mount that simply lifts the mounting point
to a height so that the prop is the appropriate depth under water.  A custom
welding shop should be able to fab something up in aluminum so that the
motor can be mounted approx. 16-18" above the kayak deck.  This mount should
be bolted directly behind the cockpit and hold the motor a short distance
away from the side of the boat - a counterbalance on the other side of the
boat will counteract any tendency of the motor weight to lean the kayak.  Be
sure to use some sturdy backer plates under all bolt locations - kayak hulls
aren't designed to take the type of stresses this will create.  Reaching up
and behind you to steer will enhance your shoulder flexibility - or pay for
a year of your orthopedic surgeon's daughter tuition at Harvard Law.

  The motor mount may interfere with paddle placement or paddler entry
during paddle float re-entries.  This might be a good reason to develop a
new paddle float rescue using paddle placement in front of the cockpit.  
 
  Seriously now - this would be a fairly easy proposition even in a canoe -
there are bolt-on motor mounts widely available or even square stern canoes.
Trying to do this with a seakayak strikes me as somewhat akin to trying to
turn a Pentium III chip into a toaster - you can do it, but why?  There are
boats designed for flats fishing, and even boats that aren't specifically
designed for flats fishing that would do quite well.  For a fairly modest
sum I'd bet you could find a used 14' jon boat (square bow and stern, flat
bottom) and a small used outboard and trolling rig.  

  I think the saying goes something like, "there's a proper tool for every
job".
