Eagle Accura 240

I just picked up a used Eagle Accura 240 to mount on my beater yak.
Has anyone had any experience with the E.A. 240?
Any tips or suggestions regarding mounting/positioning?

I plan on mounting it between the frount hatch and foot wells. There is already a screw there that holds the foam between the foot wells. Can I use just one screw into that already exisint hole to mount the EA240? It doesn't seem like it would really be stable, unless I put some really big washers underneath...The base of the EA240 has a hole in the middle and four on the outside.
I guess I can play around with some double sticky tape, just to see how it'll look and hold.

Any suggestions are appreciate it.
