absorbing sea water into the hull. If the hull is "corded," obtain a fiberglass sealing kit
from your local marine supplier to seal the cording before installing the sea cock,
eliminating the possibility of "water logging" your hull. This is also true of water out
thru-hulls.
IMPORTANT
FAILURE TO SEAL A “CORDED” HULL MAY RESULT IN SERIOUS
DAMAGE TO THE BOAT’S STRUCTURE.
Note: The threads on the foot scoop end about 3/8 of an inch from the actual foot scoop.
If after drilling the hole for the foot scoop you discover that your hull is thinner than 3/8
inch, you will need to reinforce the hull with a 6” x 6” pad to “shim up” to insure the nut
tightens correctly. We usually use ¾ inch marine grade plywood to fashion the pad.
Apply fibreglass on both sides of the pad and affix to the inside of the hull. After the
fiberglass has cured, assuming that you had already drilled the hole for the foot scoop
through the hull, then drill through the pad from the outside of the hull to insure proper
alignment through the pad and hull. Do not attempt to drill through the pad from the
interior of the boat.
Before installing the sea cock, apply a bead of marine sealant around the foot scoop and
mounting post. We recommend "3 M" 5200 brand or a sealant brand of equivalent
quality.
Insert the foot scoop up into the boat with the scoop intake facing toward the bow
(foreword) and secure it to the hull with (2) 1/4 inch flat head s/s screws. We
recommend that the screw holes be predrilled with the appropriate size drill bit to
eliminate cracking of the outer gelcoat of the hull. When drilling the holes, take care not
to drill through the hull. Use a hand held screwdriver to eliminate stripping the hole out.
These screws are intended only to keep the foot scoop from turning under the boat when
the inside fastening nut is tightened down.
Inside the boat, attach the bronze retaining nut to the sea cock threaded post. Using an
appropriate size tool or slip jaw pliers, tighten the nut to the hull snugly to insure that it
will seal against the hull. After tightening the nut completely, cover it with a thick coat
of marine sealant from the post out to about 1 inch from the nut onto the hull.
Now that the foot scoop is mounted, the ball valve (shut off valve) can be attached.
Generously coat the foot scoop post threads with marine sealant and screw the ball valve
onto the post. After the ball valve is fully tightened on the post, check the action of the
shut off arm to make sure it can be fully opened and closed without interference with the
boat structure, the water hoses when they are attached or any other obstruction. If
interference is encountered, turn the ball valve on the post to a position that allows proper
operation. CLOSE THE VALVE, REPEAT, CLOSE THE VALVE!
To connect your water hose you will need a 90 degree "thread to hose barb" fitting and a
¾ inch “closed end nipple.” Using 3M 5200, thread the ¾ inch “closed end nipple” to
