NOTE: You will drill the third mounting hole and finalize the installation after you
route the cable and test and finish the installation in the following procedures.
Transom Transducer Installation
6. Adjust the transducer assembly vertically,
until the seam on the leading edge of the
transducer (the edge closest to the transom of
the boat) is level and just slightly below the
hull (Figure 23).
NOTE: The XNT 9 28 T (Dual Beam transducer) has a natural
downward slant of 4 to 5 degrees from leading edge (closest
to the boat transom) to trailing edge (farthest away from the
boat). Looking at the back of the transducer, the seam should
be slightly below the bottom of the hull.
NOTE: A downward slant is not required for the XNT 9 DI T
(Down Imaging transducer). Adjust the running angle so that
the transducer is parallel to the water, and submerged in the
water, so that the beams point straight down during
operation.
7. Continue to adjust until the bracket is also
level from port to starboard (horizontally level
as you look at the transducer from behind the
boat [Figure 24]).
8. Mark the correct position on the transom by
tracing the silhouette of the transducer
mounting bracket with a pencil or marker.
9. Tighten the pivot bolt, using the pivot screw
and nut to lock the assembly. Hand tighten
only!
CAUTION! Do not use a high speed driver on this
combination of fasteners. Hand tighten only.
10.Hand-tighten the two mounting screws.
