Good idea to track the leak (leaks) down if you can
and fix them where they stand if you want the
shortest possible job. I could not find my
leaks… so I removed the fixed ports…and am
glad it did. The whole interior wood area under
the port from was wet…so I was happy to dry it
out. This also gave me a chance to test the seal
between the plastic panel to frame which looked bad.
I placed the whole port, external side up, on a
level table top with newsprint under the whole
port. I carefully filled the fram with water as
high as I could get it. I let it side there for
days. Then carefully removed some of the water and
lifted the port. There were no wet stains on the
paper…so I was pretty sure there were no leaks
(granted that this is not a high pressure test, but
better than nothing).
I was already equiped to replace all of the
Beckson opening ports and had their instructions
and all the materials at hand. Key points are:
-
Clean the area where the port seals against the
external cabin side VERY THOROUGHLY. Us no soap
(because silcone will not seal to a soapy residue).
Us a mildly abrasive pad and alchohol or gelcoat
degreaser…and elbow grease…to get every last bit
of old caulking off. Do the same for the aluminum
frame.
-
Beckson recommends that you do a test fitting
with a few screws to locate the port in its proper
place, and then gently “paint” a soapy solution on
the external fiberglass cabin side around the
outside perimeter of the the aluminum frame. This
will act as a release agent for the caulking that
oozes out when you reinstall the port and pull the
frame down. But… you MUST USE A VERY DRY
BRUSH…or soap will run down into the sealing
surface. This step is not completely
necessary…but it does make the cleanup process
easier.
-
Apply Dow silcone sealant (will give the exact
product number tomorrow) to aluminum frame and
reinstall the frame. This is a two person job.
Install all of the screws…but don’t pull them down
tight. Leave a turn or so until the next day.
This will allow the caulking to harden up a bit
before it is mashed flat…effectively giving you a
thicker “gasket” area between the frame and the
boat. Don’t try to clean up the caulking that oozes
out.
-
In a day or two, come back and tighten the
screws, super tight is not necessary. If the
cauking seems very firm, then you can cleany cut it
away with a new sharp razor blade. GENLTLY insert
the blade perpendicular to the cabin side and just
touching the aluminum frame, and trace the blade
round the frame. Use the lightest of finger
pressure so that you do not scratch the gelcoat.
The silicone is very easy to cut. Remove excess
caulking…patiently…never digging down into the
caulk between the frame and the cabin side.
We reinstalled all ports using this method on our
F30…and not a leak in the last 6 months. I only
wish that I had replace the plastic glazing on the
fixed ports at that time…because there are
definitly showing their age.

an expert since I still have some leaks, but I have
to second Mike’s suggestion to check the fit of
the outside frame to the coach top side. When I
started looking at that, I found that the bottom of
one of the aluminum fixed ports was a good 1/8"
away from the side of the coach top. Don’t know
whether the frame was bent or the coach top buckled,
but there was plenty of room for water to be
wicked in. I taped the coach top and injected
caulking up into the gap and that leak, at least,
seems to have stopped.

again
I have a 30 and from the sound of it the port
installation is a bit different, however I did
have a
leak a while bck n I think my experience may be
relevant.
There are two wys for a leak to happen
- There is a leak between the frame and the hull
- Leakag betwen the glass and the frame
Before you attack you should try to determine which
type of leak you have.
Mine was frame to hull along the top lip of the
frame
where a small secton of the sealing compound had
failed. I used one of those small disposable
plastic
box cutters,the kind that has the break off
blades.
Extended the blade about an inch and a half and was
able to slide the blade between the frame lip and
hull
to thoroughy clean the old sealant out. Then bot a
fabric glue syringe (these things are worth their
weight in gold, I got a bunch on the boat) filled it
with a few ccs of sealant and injected sealant
into
the narrow gap I had created between frame and
hull.
Th leak was stopped and I’ve been good for several
years now.
I have also removed the window from the frame for no
reason other than to clean up the ratty plumbers
gasget material that was originally used by
Freedom to
seal the glass to the frame. This is a big job and
IMO
sholdbe avoided at all costs unless you have
absoultely confirmed this is the source of the
leak.
Finding the source can be a challenge. I did it by
creating a cofferdam above and around the port with
rags and setting up a slowly running hose to
provide a
skein of water on the exterior. Remove the
interior
trim frame and begin the search. Freedom went wild
with the black silcone round the glass (it not
only
covers the glass edge, it also obscures the
interior
frame to hull interface) so I found that I neeed
to
cut some of the excess away to be able to see the
frame to hull interface. Sure enough, after a
littie
detective work I was able to trace the leak to a
one
inch area between hull and frame which I proceeded
to
repair as above.

Please!
The fixed portlight over the galley on my 1986

I’m trying to remove it to rebed it. So far I
have
gotten the
aluminum trim off the inside which revealed
large
amounts of
silicone-like caulk surrounding the U shaped
channel.
It looks like the following:
