Transom Repair
From April to August of 2005 I
learned all about fiberglass repair.
The following pictures document my efforts. The first picture is the
most recent.
Scroll all the way down to see the steps I took to get this far.

Done !

Ready for mounting.

After more sanding and
applying the Gelcoat.

This is sanded after the
second layer
of fiberglass mat. It's almost ready for the Gelcoat.
![](allglass.JPG)
Entire transom is now covered
in one layer
of fiberglass mat. I will sand it and add another layer.

Full view showing the
insulation sanded and covered with more BondoGlass® which
was also sanded. I can now cover the entire transom in several layers
of fiberglass mat.

I used more BondoGlass®
around the edges of the plywood to fill in the gap between the
old fiberglass and the plywood, then sanded it smooth in preparation
for some fiberglass mat.
![](plywood.JPG)
The last sheet of plywood has
been attached using Bondo® resin.

Fiberglass mat has been added.
![](allbondoglass.JPG)
It took 30 cans of BondoGlass® to get the transom smooth enough for the plywood.
![](almost.JPG)
Almost done adding what I
hope to be the last bit of BondoGlass®.
![](topsanded.JPG)
Closeup of BondoGlass® after sanding.
![](topleftglass.JPG)
Closeup showing how the
BondoGlass® sticks to the boat, but not the
plywood covered with contact paper. This area is now ready for sanding.
![](contact.JPG)
I found that by applying a
sheet of contact paper to the inside area of
the last
sheet of plywood, I was able to mix 1 can of BondoGlass® and apply
it to
the contact paper in the next area to be covered. I then sandwiched in
the fresh
BondoGlass® onto the boat using clamps all around the transom. The
BondoGlass®
only sticks to the boat, but not the contact paper, which then gave me
time to sand, etc.
![](fullglass.JPG)
After sanding the matting,
more BondoGlass® was added, one section at a time,
because the resin sets in less than 5 minutes after mixing with the
hardener. I wasted
at least 2 cans when trying to mix up too much and ran out of
time. DOH!
![](outsideglass1.JPG)
Fiberglass mat has been added
and covered with Bondo® resin.
![](outside3.JPG)
After applying more
BondoGlass® and sanding.
![](outsidetop2.JPG)
BondoGlass® has
been used to fill in the gaps. The transom is
starting to look like it
may actually hold a motor once again!
![](insidetop.JPG)
Top inside of transom
showing new plywood.
![](outsidetop.JPG)
Top of inside transom has
been reinforced with plywood attached using BondoGlass®.
![](outside2.JPG)
More BondoGlass® was
used to fill in the gaps. The transom is now even MORE solid than
before!
![](outsidejack.JPG)
A second piece of plywood
was used to fill in the gap where the old fiberglass was removed.
This was held in place with the old trailer jack similar to the inside
repair.
![](outside.JPG)
BondoGlass® was used on
outside of transom as well, then coated with Bondo® resin.
![](inside.JPG)
BondoGlass® was used to
seal in the new plywood. It is VERY solid now!
![](insidejack.JPG)
I used an old trailer jack
to keep pressure on the new plywood inside transom to create a tight
fit.
![](before9small.JPG)
Bilge area needed
reinforcing so I used a thin piece of plywood, then covered with
Bondo®.
![](before8small.JPG)
Bilge area was sanded
down and Bondo® was used to level the area.
![](before5small.JPG)
New plywood has been
fiberglassed and fitted inside transom.
![](before4small.JPG)
Jagged area of remaining
fiberglass has been trimmed away.
![](before3small.JPG)
Old wood has been
removed and sanded down to remaining fiberglass.
New plywood has been setup
inside transom for support.
![](before2small.JPG)
Wood is wet and rotten and must be
removed.
