Interphase Sea Scout Operation Manual page 13

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 Sea Scout
on the water, you may need to readjust the transducer's
mounting for optimum performance.
