FishFinder Powered and Mounted

First off thanks to all the feedback from everyone about my fishfinder. Above is the link where I have a few pics. 

I have an unique set up because my kayak is a hybrid an Old Town Angeler DLX so I started with the mount for the unit in the cup holder.  I used 1/8" drill bit where the bolts would go but the first hurdle was I could get my drill in the back hole.  This was because the locking mechanism on drill was hitting the mount and not allowing the bit to go all the way so I just marked the other two holes with the center of my finger and rotated the mount around so the back hole lined up and made a mark.  Then I used 3/8" toggle bolts to hold it tight. 

The battery box is a $2 Ziploc box with 5/8" rubber stopper with 3 1/8" holes drilled and the wires running through the stopper.  Then the wires just hook right up to the 12v 7.2aph battery the ducer is next.  I am going with the duct seal well strategy.
