<< Lee, greetings.
 
 I read your account with interest.  For those of us without engine access 
 problems, your experience is still useful for what you found when you cut 
 open your icebox.  I wonder:  Was the insulation cavity -- the space in 
which 
 you found the styrofoam and newspapers laid in -- one continuous space, or 
 was it baffled, or compartmentalized?  It occurs to me that one might cut a 
 couple of access holes in the interior of the box, pull out the old 
material, 
 and fill it with some sort of injectable foam/gel sort of insulation.  Would 
 that seem to you -- having now had the exerpience of dismantling the icebox 
 and having seen the interior construction -- to be a workable fix for the 
 icebox?  If so, do you have any suggestions about how best to proceed on 
such 
 a project?

Hi Sanders,
No, there were no baffles of any kind inbetween the fiberglass liner and the 
wooden case.  I think your solution to improving the insulation of the ice 
box should work fine. It will betough to break up the styrofoam sheets and 
fish out the pieces through holes in the liner, but not impossible.One caveat 
though- I did find some rot begining in the aft wall of the ice box, from 
where water had worked in through the cockpit access.  The drain hoses that 
should have carried the water from the lip in the hatch were clogged, and the 
overflowing rain water had done the damage.  When you cut your access holes, 
try to inspect as much of the wood as you can see, and if you find 
superficial soft wood, spraying some git rot or other thinned epoxy on the 
wood may be a good idea. The inside of the wooden case had no paint or finish 
on it at all, and sprayed foam insulation might trap moisture against it, 
causing rot to start.  You might want to make the access holes big enough, or 
make enough small ones, so you could coat and seal the wood surface with 
epoxy, before spraying in the foam.  
Hope this helps,
Lee
