Interphase Proble Operation Manual page 14

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 the right.
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
down. Check the location of your boat's waterline and
position the flat top surface of the transducer so that it is
parallel to the waterline as shown below.
Note: If the transducer is not mounted so that its fore
and aft direction is parallel to the surface, then the
forward looking display will be distorted and flat
bottoms will appear to be slanted upwards or
downwards. After mounting the transducer and actually
using the Probe on the water, you may need to readjust
the transducer's mounting for optimum performance.
