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,
this will void your warranty.
Following are some tips and basic installation instructions for three popu-
lar transducers. Detailed installation instructions are provided in the trans-
ducer kits.
Transom Mount Installation
010-10248-00 (depth/temp) Transom Mount Transducer.
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.
OK
Mount the transducer parallel with the bottom.
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.
