Installation Preparation

Before permanently installing any part of your echo, plan the installation by
determining the location of the various components. Verify that the cables are
long enough to connect the components to each other and to power.
about the transducer
The transducer is the component of your echo that transmits sound waves
through the water and receives them to relay the information to your echo
device. With the supplied hardware, you can install the included transducer
on the transom of your boat (page
If you already have an existing Garmin 6-pin dual-beam transducer on your
boat, you can use it with your echo device by installing an adapter cable (sold
separately).
about the echo Mount
The echo device can be mounted using the included swivel-mount bracket
(page 3), or it can be mounted flush with the dashboard using the appropriate

Installing the transducer on a transom
Selecting a transom-mount Location
Select a transom-mount location while considering these guidelines for
optimal performance.
• Mount the transducer as close to the center of the boat as possible.
• Do not mount the transducer 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.
3).
• Do not mount the transducer in the path of the propeller on single-
drive boats.
The transducer can cause cavitation that can degrade the performance
of the boat and damage the propeller.
• On twin-drive boats, mount the transducer between the drives, if
possible.
• Do not mount the transducer in a location where it might be jarred
when launching, hauling, or storing.
