Installation Instructions
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the chartplotter or fishfinder 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
Failure to install and maintain this equipment in accordance with these instructions could result in damage or 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.
This equipment should be installed by a qualified marine installer.
To obtain the best performance and to avoid damage to your boat, you must install the Garmin® device according to these instructions.
Read all installation instructions before proceeding with the installation. If you experience difficulty during the installation, contact Garmin Product Support.
Tools Needed
•Drill and drill bits
•Number 2 Phillips screwdriver
•Masking tape
•Marine sealant
Preparing the Transducer for Long-Term Exposure to Water
NOTICE
Do not use acetone or acetone-based products on the transducer. Acetone damages the plastic transducer housing.
When you install a transducer on a boat that spends a significant amount of time in the water, you should coat the transducer and mounting hardware with a water-based antifouling paint to prevent marine growth.
1Lightly sand the transducer and mounting hardware with a fine-grit abrasive pad.
2Wipe the transducer and mounting hardware with isopropyl alcohol.
3Apply water-based anti-fouling paint to the transducer and mounting hardware.
Mounting Consideration
To ensure peak performance with the lowest noise and interference, you should route the transducer cable away from ignition wires, house batteries and wires, trolling motor batteries and wires, and high-energy wires such as radar, audio amplifier, and autopilot pump wires.
Installing the Transducer on a Transom
Mounting Location Considerations
•The transducer should be mounted parallel to the water line.
•The transducer should be mounted as close to the center of the boat as possible.
•If your propeller moves clockwise when the boat moves, the transducer should be mounted on the starboard side.
•If your propeller moves counter-clockwise when the boat moves, the transducer should be mounted on the port side.
•The transducer should not be mounted behind strakes, struts, fittings, water intake or discharge ports, or anything that creates air bubbles or causes the water to become turbulent.
The transducer must be in clean (non-turbulent) water for optimal performance.
•The transducer should not be mounted in a location where it might be jarred when launching, hauling, or storing.
•On single-drive boats, the transducer must not be mounted in the path of the propeller.
The transducer can cause cavitation that can degrade the performance of the boat and damage the propeller.
•On boats with outboard or inboard/outboard motors, the transducer should be mounted at least 38 cm (15 in.) from the propeller.
•On twin-drive boats, the transducer should be mounted between the drives, if possible.
Assembling the Transducer with a Transom Mount Bracket
1 Attach the mount to the transducer with the included
ÀÁ
star washers , and screws .
ÂÃ
2 Attach the mount to the bracket with the bolt , rubber
Ä Å washer , flat washer , and lock nut .
Æ Ç È
NOTE: The bolt should be tight enough to hold the transducer in place when the boat moves at high speed, but loose enough to allow the transducer to pivot out of the way if the transducer hits an obstruction.

Installing the Transom-Mount Hardware
NOTICE
If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened.
The cables connected to the transducer should not be cut, because cutting the transducer cables voids your warranty.
1 |
Cut out the template. |
2 |
With the template À aligned vertically on the transom at the |
|
installation location (Mounting Consideration, page 1), place |
the bottom corner of the template on the edge of the
Á
transom.
3 Mark the center location of the two holes of the template. 4 Remove the template from the transom.
5Wrap a piece of tape around a 4 mm (5/32 in.) bit at 18 mm (7/10 in.) from the point of the bit, to avoid drilling the pilot holes too deep.
6If you are installing the bracket on fiberglass, place a piece of tape over the pilot-hole location to reduce cracking of the gel coat.
7Using the 4 mm (5/32 in.) bit, drill the pilot holes approximately 18 mm (7/10 in.) deep at the marked locations.
8Apply marine sealant to the included 20 mm screws, and attach the transducer assembly to the transom.
9 Route the cable under the transom mount cable hook.
10If you must route the cable through the transom, choose a pilot-hole location well above the waterline and mark it.
11Place a cable clamp on the transducer cable, approximately halfway between the transducer and the top of the transom or the pass-through pilot hole.
12Mark the pilot-hole location for the cable clamp, and using a 3.2 mm (1/8 in.) bit, drill a pilot hole approximately 10 mm (3/8 in.) deep.
13Apply marine sealant to the included 12 mm screw, and attach the cable clamp to the transom.
14If you marked a pilot hole in step 7, choose the appropriate drill bit to drill a pass-through hole completely through the transom:
•If you have the 4-pin cable, use a 16 mm (5/8 in.) drill bit.
•If you have the 8-pin cable, use a 25 mm (1 in.) drill bit. 15Route the transducer cable to the sounder:
•If you are routing the cable using a pass-through hole, push it through the pass-through hole, and install the cable-entry cover (Installing the Cable-Entry Cover, page 2).
•If you are not routing the cable using a pass-through hole, route the cable up and over the top of the transom.
You should avoid routing the cable close to electrical wires or other sources of electrical interference.
Installing the Cable-Entry Cover
If you routed the cable through the transom after you installed the transducer, you should install the cable-entry cover to keep water from entering your boat.
1 Place the cable-entry cover over the hole and the cable,
À
with the opening pointing downward, and mark the location of the two pilot holes.
2Remove the cable-entry cover, and, using a 3.2 mm (1/8 in.) bit, drill the pilot holes approximately 10 mm (3/8 in.) deep.
3Fill the pass-through hole with marine sealant so it covers the cable completely and there is excess sealant around the hole and the cable.
4Place the cable-entry cover over the hole and the cable, with the opening pointing downward.
5Apply marine sealant to the included 12 mm M4 screws, and attach the cable-entry cover to the transom.
6 Wipe away all excess marine sealant.
Testing the Installation
NOTICE
You should check your boat for leaks before you leave it in the water for an extended period of time.
Because water is necessary to carry the sonar signal, the transducer must be in the water to work properly. You cannot get a depth or distance reading when out of the water. When you place your boat in the water, check for leaks around any screw holes that were added below the water line.
Testing the Transom-Mount Transducer Installation
NOTICE
When adjusting the depth of the transducer, make the adjustments in small increments. Placing the transducer too deep can adversely affect the performance of the boat and put the transducer at risk of striking underwater objects.
Test the transom-mount transducer installation in open water free of obstacles. Pay attention to your surroundings as you test the transducer.
1 With the boat in the water, turn on the chartplotter.
