TRANSDUCER INSTALLATION
If you have a transom mount transducer you can mount it on the transom (preferred), in
the hull, or you can purchase the trolling motor adapter and mount it on your trolling
motor. If you have a puck transducer then you can ONLY mount it in the hull; there is a
separate inside the hull mounting section for puck transducers. Find the correct section
for your transducer installation type.
The included transducer is designed for transom mounting on the boat (directly exposed
to the water). On fiberglass hull boats, this same transducer can be bonded to the inside
of the hull. When mounted inside the hull, the sonar signal actually passes through the
hull of the boat. One of these two mounting techniques will produce acceptable results
on most boats. There are, however, several situations that may demand a different type
of transducer. Inboard boats, wood or metal hulls, and sailboats often have unique
transducer mounting requirements.
TRANSOM TRANSDUCER INSTALLATION
1. Locating the Transducer Mounting Position
NOTE:
If transom mounting is not possible because of a
stepped hull or cavitation noise, and you have a single layer
fiberglass hull, In-hull installation is an option. See
Inside the
Hull Transducer Installation
for more information.
Turbulence:
You must first determine the best location on
the transom to install the transducer. It is very important to
locate the transducer in an area that is relatively free of
turbulent water. Consider the following to find the best
location with the least amount of turbulence:
• As the boat moves through the water, turbulence is
generated by the weight of the boat and the thrust of
the propeller(s) - either clockwise or counter-clockwise.
This turbulent water is normally confined to areas
immediately aft of ribs, strakes or rows of rivets on the
bottom of the boat, and in the immediate area of the
propeller(s). Clockwise propellers create more
turbulence on the port side. On outboard or
inboard/outboard boats, it is best to locate the
transducer at least 15" to the side of the propeller(s)
(See the illustration
Turbulence-Free Location
).
