Mounting the Transducer
Proper transducer installation is key to getting the best performance
from your new unit. If the transducer lead is too short, extension cables
are available from you GARMIN dealer. DO NOT cut the transducer lead
or any part of the transducer cable, as this will void your warranty. The
cable cannot be spliced and connected to any existing (GARMIN or non-
GARMIN) transducer cables.
Following are some tips and basic installation instructions for the
optional dual frequency transducer and speed sensor. Detailed installation
instructions are provided in the transducer kits.
Transom Mount Installation
Dual Frequency Transom Mount Transducer (with depth/temp).
DO NOT mount the transducer behind strakes,
struts , fi ttings, water intake or discharge ports, or
anything that creates air bubbles or causes the
water to become turbulent. It is important that
the transducer be in calm, non-turbulent water for
optimal performance.
Do not mount transducer directly in the
path of the prop. The transducer can cause
cavitation that may degrade the boat's performance
and damage the prop.
Make sure that the transducer is
below water level when the boat
is on plane at high speed
Mount the transducer cable cover
well above the waterline.
Transducer should extend 1/8" below
fiberglass hull or 3/8" below aluminum hull
Apply marine sealant to all
screw threads to prevent water
from seeping into the transom.
Mount the transducer parallel with the bottom.
OK
NOTICE: The Transom Mount Transducer and
the Speed Sensor must be installed separately.
These two devices may not be combined.
