INSTALLATION INSTRUCTIONS
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the chartplotter, fishfinder, or sonar module product
box for product warnings and other important information.
You are responsible for the safe and prudent operation of your vessel. Sonar is a tool that enhances your
awareness of the water beneath your boat. It does not relieve you of the responsibility of observing the water
around your boat as you navigate.
CAUTION
For the best possible performance and to avoid potential injury, damage to the device, or damage to your vessel,
installation by a qualified marine installer is recommended.
Failure to install and maintain this equipment in accordance with these instructions could result in damage or
injury.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
Read all installation instructions before proceeding with the installation. If you experience difficulty during the
installation, contact Garmin
®
Product Support.
To prevent interference and avoid possible overheating damage, do not install the transducer near the engine or
in the engine room.
To prevent damage to the cable and the transducer, do not use the cable to pick up or pull the transducer.
Always operate the transducer when it is submerged. Operating the transducer when it is exposed to the air may
result in damage due to overheating.
To prevent permanent damage to the surface of the transducer, do not use solvents such as mineral spirits,
acetone, Methyl Ethyl Ketone (MEK), or similar products when cleaning. Do not use a power sander or pressure
washer to clean the transducer.

Page 2: Software Update
When installing this transducer, it is critical that you install it according to the material of the boat hull. The GT17M-THF transducer housing is made from stainless steel, and it can be installed in a fiberglass, wood, composite, aluminum, or steel-hulled vessels. When installing this model in an aluminum or steel hull, you must install the included galvanic isolation components as instructed. -
Page 3: Mounting Location Considerations
Mounting Location Considerations • On outboard and sterndrive vessels , the transducer should be mounted in front of and close to the engine or engines. • On inboard vessels , the transducer should be mounted in front of and far away from the engine propeller and shaft. - Page 4 Deadrise Angle The deadrise angle is the measurement of the angle between a horizontal line and the outer hull at a single point. These transducers are available in a selection of pre-configured angles from 0 to 20 degrees. For optimal performance, it is critical that the transducer angle you purchase is as close as possible to the deadrise angle at the installation location.

Page 6: Installing The Transducer
Sealing the Core with Casting Epoxy To properly seal the core with casting epoxy, you must create a cylinder with an outer diameter of 98 mm (3 in.) to act as a spacer as the epoxy sets. 1 Coat a 98 mm (3 in.) cylinder with wax. - Page 7 Preparing the Transducer for a Metal Hull 1 Place the flange isolator and the housing isolator on the transducer. 2 From outside the hull, insert the transducer through the mounting hole and hold it in place. 3 Using a knife or scissors, trim the housing isolator so it is flush with the surface of the inner hull. NOTE: The housing isolator must be flush with the inner surface of the hull so that it will not interfere with the spacer when you tighten the jam nut.

Page 8: Completing The Installation
Completing the Installation 1 Insert the transducer through the mounting hole, using a twisting motion to squeeze out excess sealant. If your transducer has an internal angle of 12 or 20 degrees, you must make sure the arrow on the top cap points to the keel of the boat, so that the internal angle of the transducer element will offset the deadrise angle of the hull. -
Page 9: Maintenance
If the transducer cable is not long enough to reach the chartplotter or sonar black box, you can purchase an extension cable from your Garmin dealer or buy.garmin.com. 1 Route and connect the transducer cable to the chartplotter or sonar black box while taking these precautions. -
