2) Choose a location where the transducer can be
mounted so that it will be level to the water’s surface and
will not be tilted to either side.
3) The transducer must always remain submerged,
regardless of the speed of the boat and should not be
mounted where it could be damaged by underwater
obstacles or when loading on a trailer.
4) DO NOT locate the transducer in the extreme
bow of the boat where it will be subject to intense
turbulence as the boat pounds through the water.
5) DO NOT locate the transducer directly behind
any hull protrusion which will cause the water to be
turbulent when it reaches the transducer. For
displacement-hull power and sail boats, the thru-hull
installation is usually required.
DANGER: DO NOT allow any solvents, i.e. gasoline,
acetone, to come in contact with the transducer or head
unit as this may dissolve the plastic material.
Transom Transducer Installation
The transom transducer is attached to the boat with two
stainless steel brackets. The brackets should be mounted
to the ears on the top of the transducer using the hardware
supplied. All metallic parts are stainless steel to resist
corrosion. Good operation up to 40 - 50 MPH is usually
possible. Obtaining operation at higher speeds is possible
but may require considerable experimentation with
transducer positioning.
Transom Mounting Location
On single drive installations, it is strongly recommended
that the transducer brackets be mounted on the side of the
boat where the propeller blade is rotating downwards
which usually is the right (starboard) side. To reduce the
possibility of disturbing the water flow to the propeller,
the transducer should be located about 2” outside the
swing of the prop. If possible, the transducer and bracket
should not be mounted directly behind any strakes, ribs,
intakes and outlets for live wells and/or engine cooling
water, or any protrusion which may cause turbulence or
cavitation. For dual engine installation, just off the center
line is usually acceptable.
