Thru-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

in. (4 mm) thick, on the inside of the outer lip and

on the threads of the Intelliducer. Ensure the sealant extends at least

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.

Push firmly to squeeze out excess marine

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.

7. Allow the sealant to dry completely as specified by the manufacturer of the sealant.
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 first 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
