minimize noise pickup and provide as clear a view as
possible of the water ahead of the boat. Study the hull
shape of the vessel carefully to determine the best
transducer mounting location. To achieve optimal
operation the transducer should be mounted in a spot
which:
* Minimizes acoustic noise reception.
* Minimizes the chance that aerated water
will flow across the transducer's frontal
nose area.
* Optimizes the transducers view of the area
ahead and directly below the boat.
The transducer can be installed on either side of an
outboard or inboard/outboard engine, or between twin
outboards. For single engine installations, normally 18"
to 24" outboard of the propeller center line is acceptable
and the down stroke side of the propeller is preferred.
Choose a location where water flow is smoothest. For
dual engine installation, just off the center line is usually
acceptable.
Because the transducer rotates back and upwards when
the bracket releases, it must be mounted in a location
where there is sufficient clearance and headroom to
allow the full release.
Attaching the Transducer and Spray Shield
to the Bracket
Locate the Stainless Spray Shield inside the transducer's
stainless mounting ears. Make sure spray shield is
orientated as shown in sketch on following page.
Then, assemble the stainless kick-up bracket to the
transducers using the 4 screws, washers and lock nuts
provided. The bracket arms must be mounted outside
the stainless steel mounting ears of the transducer. Do
not fully tighten the lock nuts at this time.
Position the transducer so that it is perpendicular from
side to side and make sure the rounded shaped area is
pointed towards the front of the boat.
Mounting the Transducer to the Boa
After you have selected the optimum mounting location
and have assembled the mounting bracket to the
transducer, mount the bracket onto the hull as shown on
the right.
Make sure to position the transducer so that it is level in
the fore and aft direction and so it will look straight
