Anyone use a shoot through the hull transducer in their kayak. I'm thinking of picking up a lowrance elite 4x.

Don't see why you can't, as long as there is not a double layer.

What kind of kayak do you have? SOT or sit inside? I know that some guys do it that way, but it will throw off your temp gauge.  In the spring and fall when temperature can be really important in finding the fish you will be missing out on that.  If at all possible I would suggest rigging it in the water.  You will get a better image and still have the temp gauge working. 

I have a wilderness ride 115. I'm not sure if I should rig it through a scupper over the side or through the hull

My suggestion would be to go through the scupper.  I have a jackson cuda 12 and have it run through the scupper.  Works perfect as it sits up in the scupper a little so I am not worried in any way of it getting hit or damaged, but it has a clear shot through the water and temp is not effected.  Looks like the way the wilderness scuppers are located it is pretty protected as well.  This where I got my idea....it has worked very well.  I am sure you could modify it how you need it to fit your wilderness ride.
