As I mentioned, I can't get to the outside of the box to see the 
insulation.  No access.   The fact the lid gets hot both on the inside 
and the outside (lid is 3" or more thick) tells me it's conduction 
through solid material, at least in part.

It's a center cockpit with pretty much no chance of getting a large 
volume of air exchanged.  The only outlet is through the binnacle where 
there is a 3" x 24" louvered vent.  I'm lining that vent with 7 60 MM 
muffin fans.  I'll see what that does.

The existing insulation in the engine compartment has a reflective 
surface.  I'll try some additional insulation.

Jim.
