Transom Transducer Installation

1. Locate the Transducer Mounting Position

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:
Areas of Possible Turbulence
Rivets
Transom
Strakes

• 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
Hull
side. On outboard or inboard/outboard boats,
it is best to locate the transducer at least 15"
to the side of the propeller(s) (Figure 11).
• The best way to locate turbulence-free
water is to view the transom while the boat
is moving. This method is recommended if
maximum high-speed operation is a high
priority. If this is not possible, select a
location on the transom where the hull
forward of this location is smooth, flat and
free of protrusions or ribs (Figure 9).

• On boats with stepped hulls, it may be
possible to mount the transducer on the
step. Do not mount the transducer on the
transom behind a step to avoid popping the
