sceptre transom cooler

[floorboy]

I am thinking about how (if I can) to put a cooler/livewell in the transom of my sceptre. It would be maybe 48x10x 10-11 inches deep. It would serve mainly as a cooler for "pop" I'm not concerned with the little bit of weight on the stern.
Has anybody done this? Is there a hinge that is similar to a hood hinge on a car the could be mounted underneath? I don't see anything else working with the arch. Something that comes up and back if you follow me.
The box would drain into the scuppers.
Another reason I want to do something is so I can mount my washdown pump as I have no chance of squeezing any part of me in there to mount it. [img]/forum/images/graemlins/tongue.gif[/img]

Still in the planning stages, open to input. Thanks.
