One other thing they did wonderfully was make it easy to install fishfinders. Poking around online provided some good information on how to install a Humminbird. Both brands are owned by the same parent, Johnson Outdoors, so naturally they would like to support each other.
Ocean Kayak made it easy to install virtually any fishfinder on this boat. After digging around for a tutorial, I drew a blank. In the hope of contributing something back to the online community of kayakers who helped me, I've tried to document some of the steps that are required to make a nice, clean installation. It's not hard!
I chose a Lowrance Elite-4 as a reasonable balance of cost, size, and features. It's a combo unit that has both sonar and GPS capabilities. The color screen is nice particularly for navigation. The fishfinder is really best for identifying structure in the water that I've used it. The one feature it lacks that I would have enjoyed is some kind of trip counter so you could see not just the 'breadcrumb' trail of where you paddled, but also get stats like time, speed and distance. Ok, you could argue it's time to put the technology aside and just go fishing, but I do kind of enjoy it.
Here's where we're trying to end up.

|Transducer viewed from the side|
What's nice about the OK Ultra 4.3 is how clean you can make the installation. No cables are exposed to snag. The transducer is tucked away, protected from damage if you bump across rocks while launching. Pretty cool!
Out of the box, the transducer looks like this:

|How do you fit this thing through that tiny hole?|
In the end it wasn't that tricky. The photos and descriptions below focus on this. The remainder of the installation process is pretty straight forward. Here we go!
Turn the boat onto its side so you can work on the bottom. Ocean Kayak gave us a nice recessed pocket to install the transducers into. Notice the two threaded sockets in the pocket. They're sized perfectly for the bracket included with the Lowrance transducer.

From the bottom, thread the cables through the scupper hole above the recessed transducer pocket.
Next, we want to remove the cover for the hatch. Flip the boat right side up. In the photo below the hatch has been removed. You can see our transducer cable coming out of the scupper hole and out of the left side of the photo.
Notice the stainless steel "T" piece that hinges the hatch cover. This unconnected piece slides into the hatch. This is the hole that's too small to get your big transducer plug, through. Here's where the Ocean Kayak designers did a nice trick. The "T" is a full tube for the hinge portion (running top to bottom in the photo). However it's an open 'C' channel piece running left to right. This is where our cable is going to go.
The trickiest part of the whole job is getting the cover off the hinge. Flip the hatch open as in the photo above.
First, you need to remove the plastic cover for the recessed cable storage area in the hatch cover. It's held in place by seven screws. This is where you'll eventually hide all that transducer cable. The photo above shows the hatch cover with the cable storage cover removed. The photo below shows the cover itself.
Your cover won't have holes in it yet. Those come later when we install the combo unit mount.
Once you remove the cover, you'll see where the "T" hinge enters the hatch cover. It's held in place by a plastic bushing and a metal lock ring.

Now you install the transducer to the bottom of the boat. This fixes the length of your cable so you can tidy things up above the waterline.
In order to prevent the cable from moving around, I tied it around the "T" hinge. Highly recommended. Give it just a little slack so the hatch cover can move free without putting pressure on the cable.
|Securing the transducer cable|
The transducer cable runs down into the scupper hole. You'll notice the smaller cable going into a hole in the plastic on the side of the scupper. This is the power cable. I "installed" the battery in the boat (by which I mean I duct taped it in place to see if I liked that location, but then rejected it), but I think it would be better to move it to the stern. The cable's not long enough, so that's another project for another day.

Next you are going to modify the cable storage area cover. (Remember those holes we pointed out before).

The fishfinder's base screws directly to the cover. Ocean Kayak gave us a blank canvas to work with so virtually any fishfinder will work. Put the base on the cover, mark the location of the holes, a start drilling. I put the Elite-4 pretty much dead center. In the end we have 7 small holes around the edge to reinstall the cover to the hatch cover, four small holes to mount the Elite-4's base, and one large hole through which we run the transducer cable. If you use a different unit, make sure the location you pick will allow you to rotate and close the hatch lid with the fishfinder installed!
Install the fishfinder base to the cover and set it aside. Sorry, not photo.
Now we finally get to do something with all that cable.
|Storing the excess cable|
Now reinstall the cover on the coiled cable using the seven screws. Click the fishfinder into it's base.

Hopefully you find this useful. Total time, including head scratching and monkeying around, was a little under an hour. Enjoy!
