ent scenarios out there with used boats.
Some are caused by the manufacturer
and some by previous owners. But, as you
surmise, the issue of plugging holes in
the hull is very important.
We’re talking about holes that drain
water from the
dinghy out through
Sometimes there is
a double hull and
two plugs are used
at the aft end. One
hole is to drain the
inside of the boat
when you are on
a plane or when it
is out of the water.
The other may be
to drain the space
between the hulls,
if there is a space.
Or there may be
only one hole in
the transom – par-
ticularly when it’s a
the interior of the
boat will drain into the space between
the hulls and, from there, out of the boat.
Of course, I can only guess about yours
without seeing it.
The plug in the transom itself is
usually either inserted from inside or
outside of the transom. If you insert it
from inside the boat, the outside of the
hole doesn’t normally reveal the end of
the plug. Some prefer this because it’s
easier to pull the plug from within the
boat when you take on waves or rain.
However, many prefer to insert the plug
from the outside so that the water pres-
sure pushes it in rather than out. Some
even prefer to use two plugs in the hole
as an extra measure, assuming one doesn’t
interfere with the gripping surface of the
other within the hole. (The hole must be
deep enough for two plugs, and often it is
not.) And, of course, if there is no access
hatch to a “tween decks” area, you must
use an outside plug.
If there is no tube or sleeve in the
transom hole, and if the sides of the hole
are bare fiberglass or bare wood, odds
are that sleeve has come out. You would
need the sleeve as well as plug. There are
various tubes and plugs available. Just go
to the West Marine website (westmarine.
com) and type “transom plug” in the
search box at the top. Other suppliers,
such as Jamestown Distributors, can also
help. Standard plugs without the sleeves
are usually inexpensive and readily available in the sporting sections of stores like
Wal-Mart and Ace Hardware.
