7Thru-Hull Intelliducer Installation Instructions
Step 3: Install the Intelliducer
After you have a hole drilled and prepared, install the bottom portion of the Intelliducer in the
boat.
To install the bottom portion of the Intelliducer:
1. Apply a layer of marine sealant, at least
1
/
8
in. (4 mm) thick, on the inside of the outer lip and
on the threads of the Intelliducer. Ensure the sealant extends at least
1
/
2
in. (12 mm) higher
than the thickness of the hull, gasket, and locking ring.
2. From the outside of the boat, push the
Intelliducer into the hole with a twisting motion.

sealant.
3. From inside the boat, twist the Intelliducer so
the “Keel” marking points toward the keel of the
boat.
4. Place the gasket over the Intelliducer and press
it against the hull.
5. Thread the locking ring on the Intelliducer until
it tightens against the gasket. Hand tighten the
locking ring—do not use tools—while ensuring
that the “Keel” marking points toward the keel of
the boat.
6. From outside the boat, remove any excess marine sealant. This ensures water will pass
smoothly over the Intelliducer.

8. Test the installation for leaks.
CAUTION: Do not leave the boat in the water unchecked for several days. Ensure there are no
leaks before leaving the boat unattended in the water for more than an hour. Microscopic leaks may
not be immediately apparent and could possibly sink your boat if left unattended.
Place the boat in the water and immediately check for leaks in the installation of the
Intelliducer.
If no immediate leak is observed, check the installation
everyhourfortherst24hours.
To install the top portion of the Intelliducer:
1. Ensure the sealant has dried completely, and ensure the
installation of the bottom portion does not leak.
2. Connect the cable from the bottom portion of the
Intelliducer to the underside of the top portion
