Tray on the Edge is quite deep. I have put an additional thin layer of padding (the green one) and the long bow eye barely had some thread underneath. Rickter Edge tray is filled with foam. I put some 5200 once I drilled the hole around the foam inside the hole to try seal it as much as I can. Left it overnight and next day put the bow eye on. I also put some superglue under the lip of the bow eye and let it stick to the turf or it would sink in under the turf as you tighten it down. I hated to drill a brand new hull, however a bow eye for the surf is an absolute must.
Another thing to mention for reference, the foot holds that come from the factory are made to destroy your toes. Both of these on the pic have been cut, modified and re-turfed.
Edge FR is a heavy hull made to sustain heavy surf abuse. It also carves extremely hard. Therefore small engines are not the best option for optimum handling. I have been riding it for quite some time and recently put 950 DASA, 8mil with 148 pump built, installed and tuned by Thrust Innovations. The ski handling has improved dramatically. It comes out of turns so much easier and it becomes a lot more nimble.
I would definitely recommend bigger power for that hull if you want to have smile on your face every time you hit or slash a wave.
Other recommendations for the Edge: Throw that rubber flap scupper in the garbage ASAP and get a versiplug type. I bought mine OVP from France, but believe Thrust has them in stock now.
I havn't put tubbies yet but that will be done soon.
Whoever you order your Edge from, ask for extra soft padding on the pole shock pad. The factory piece is harder than a cement.
If you ride surf, front foot hold is an awesome thing to have as well.
