Dor,
How did you make out with the control box?
Well, the little pivot's that hold the control cables in...they do just slide out. It looks like its designed so you can place a screw in there to pull them out. ie...no need to open the box up, just pull the clip, then pull those little pivot cams out.
However, I did open the box up...which promptly had all the pieces fall out!
(Of course, right?) So...I just got the thing back together correctly. (You can make it all fit incorrectly, btw...found that out too!)
The patio set is currently sitting in the boat, so I have to wait for it to warm up so I can put it in.
I have to completely redo the wood mounting area before mounting the box, which I can't do, until I figure out what I'm doing for my permanent seating solution...
Basically, it'll likely go in over Memorial Day weekend.
On the plus side, I know get how it works, very ingenious piece of engineering!
