Thru-Hull Intelliducer Installation Instructions
Inboard engine boats
Mount forward of the shaft and propeller, and ensure the location is submerged at high
speeds.
Planing hull boats
Mount within the first set of lifting strakes, near the keel and as far aft as possible, to ensure
that the location is submerged at high speeds.
Mount on the starboard side (where the propeller blades are turning downward).
Stepped hull boats
Mount ahead of the first step and ensure the location is submerged at high speeds.
Boats capable of speeds in excess of 25 knots (29 MPH)
Consult a professional installer.
Confirm Your Intelliducer Choice
Garmin has four models of Thru-Hull Intelliducers:
NMEA 2000 NMEA 0183
0–12 Degrees (010-00701-00) 0–12 Degrees (010-00702-00)
13–24 Degrees (010-00701-01) 13–24 Degrees (010-00702-01)
After you have chosen a suitable location on your boat, ensure you have chosen the correct
Intelliducer to offset the angle of your hull and the type of data interface on your boat.
Use an angle finder or digital level to measure the deadrise angle of your hull at the chosen
mounting location. The deadrise angle is the angle measured between the waterline and the
slope of the hull.
CAutIoN: If the deadrise angle of your boat does not fall within the angle specified by your
model of Thru-Hull Intelliducer, you will not obtain accurate depth readings. Be sure to install the
correct Intelliducer for your boat.
Step 2: Drill and Prepare a Hole for the Intelliducer
After you have chosen the proper location for the Thru-Hull Intelliducer in your hull, drill a
hole in the hull to install the Intelliducer.
WARNING: Always wear a dust mask and safety goggles when drilling, cutting, filing, and
sanding.
To drill a hole for the Intelliducer:
1. Drill a 1 /
8
in. (3 mm) pilot hole from the inside of the boat.
2. On the outside of the boat, ensure the pilot hole is in the correct location; if not, seal the
incorrect pilot hole with epoxy and drill the pilot hole in a better location.
3. Use a hole saw to cut a 2 in. (51 mm) hole from the outside of the boat.
Note: If you are installing the Intelliducer in a cored-fiberglass hull, see the additional
preparation procedures provided in this section.
4. Ensure the Intelliducer fits in the hole. If needed, refine the hole using a file or sandpaper.
5. Sand the hole and the area around the hole, inside and outside the boat, using a fine
sandpaper, to ensure the sealant will properly seal the hull.
6. Clean the hole using a mild detergent or weak solvent (such as isopropyl alcohol) to remove
any dust and dirt.
