Most of the way done now. Learned a few things today. Let's see:

Unless I'm oblivious (possible) there is no place to mount a 2D Humminbird transducer flat on the bottom of the hull. Lowrance transducers fit (there were 2 in there to start with) but the bird one is bigger. To compensate I built a marvelous dam of playdough which I appropriated from my 3 year old to keep the epoxy close to the puck in the slight channel it was sitting over. We'll find out later if this worked or was a fail.

My most hated part of all boat work is running cables through the hull. Today I found out why I hate the previous owner of my boat (or at least whoever worked on it for him). Theoretically there's a string available to you to pull cables. My boat had no string. It was no doubt used and not re-fished.

After removing the seat and taking a close look up the side I found where the string should have been, in a corrugated tube that ran the corner of the boat. 10 seconds with an electrician's fish and it was through the tube. Guh! Easy.

Yes, you ride around in this boat while sitting on a chair made of gasoline. How cool.

Anyhow, here's the tube in all glory

After filling the livewell and finding my leak (o-ring on the livewell pump out pump) I buttoned it all up and put the new starter batt in.

Finished Compartment :)
