Install the Intelliducer
To install the Thru-Hull NMEA 2000 Intelliducer:
1. Choose a location.
2. Drill through and prepare the hull.
3. Install the Intelliducer in the hull.
4. Connect the Intelliducer your existing NMEA 2000 network.
OR
Connect the Intelliducer to power and a NMEA 0183-compatible device.
5. Update your Garmin chartplotter (if applicable).
Step 1: Choose a Location to Install the Intelliducer
It is very important to carefully choose a proper location on your boat to install the Thru-Hull
Intelliducer. When choosing a location, consider the following guidelines.
General
• The Intelliducer is designed for metal- and fiberglass-hull boats.
CAutIoN: Do not install the Intelliducer in a wood-hull boat, because swelling wood can break
the intelliducer and possibly sink your boat.
• Install the Intelliducer as close to the keel as possible.
• Install the Intelliducer away from obstructions and sources of interference such as the
propeller, shafts, other machinery, other sounder transducers, and cables.
• Do not mount the Intelliducer near water intake openings or water discharge openings. Do
not mount the Intelliducer behind fittings, strakes, or irregularities in the hull.
• The Intelliducer must be submerged at all times during use.
• You must be able to access the Intelliducer from inside the boat.
• Allow for 8 in. (200 mm) top clearance and 6 in. (150 mm) of clearance around the
Intelliducer to accommodate the height of the internal unit housing, and to allow for the
rotation and connection of the internal unit housing.
Hull Types
Additional, boat-specific details should be considered when choosing a location.
Sailboats
• Fin Keel – Install as close
as possible to the centerline,
1–2 ft. (300–600 mm) ahead
of the fin.
• Full Keel – Install midships,
at the point with the least
deadrise.
outboard and Inboard/
outboard engine boats
• Mount slightly forward of the engine, off of the transom.
• Mount on the side where the propeller blades are turning downward, or centered between
dual engines. Mount as far aft as possible, but out of the wash of the propellers.
