Transom Mount Locations
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 bottom left
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 Boat
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 at
left.
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 iScan V90 on the water, you may need to
readjust the transducer’s mounting for optimum performance.
