Replacing Icebox Insulation, from the Outside

[Anonymous]

I read the great posts on insulating the inside of the icebox, but what about trying this from the outside, and leaving the icebox intact?

It looks like you might be able to get at the box inside the cabinetry
without tearing everything apart by removing the stove and fiberglass
stove liner. You can get at the starboard side by removing the
paneling in the cabinet to starboard of the icebox.

Perhaps you could chop out the old, molded on foam and replace with a
higher R value sheet foam material.

Thoughts?

[Here are a couple of responses to a question about improving icebox insulation I recently posted on the old Yahoo P365 site from some of our fellow owners.  This was before I realized everyone had moved!]

[No doubt improvements can be made, but the original insulation is OK!]

We keep our boat in Turkey. In summer it is HOT, HOT, HOT!! The icebox
as it is, with a good water cooled refrigerator-system (you have the
best in the USA) installed is more efficient than most of the
surrounding boats have.  I never changed anything on the insulation. I
did apply a simple insulation under the plywood between the top and
bottom part of the box and made a dito lid.

[I am trying to find out more about the insulation and lid details.]

We have had our 365 with the original insulation for more than 20
years in S TX where summer air temps are in the 90's and water often
above 80 deg.  With an air cooled Adler Barbour (with good air
circulation) we have had much less problem keeping the box cold than
others who had fancy systems.

I would leave it alone and worry about something else first, unless
you know positively that the foam is saturated or deteriorated.

[How many Amp/hrs. does it use?]

I don't know exactly, I believe it was between 75-90A. My original
Adler-Barbour quit after 18 years of 24-7 running and I installed a
new one about a year ago. I think the new one is a bit more
efficient.

I will add two inches of insulation to the bottom to the box this month.  Plan to use blue board from owens corning and cover it with thin white panel.  All should be in stock at Home Depot.  I will keep the drain and use a plug.  the plug hole will be epoxy to keep it water tight.
