Shoot-thru-hull v.s. Transom Mounting

(Strata 128 and Strata 128 Plus Only)
Typically, shoot-thru-hull installations give excellent high speed opera-
tion and good to excellent depth capability.  There is no possibility of
damage from floating objects.  It can't be knocked off when docking or
loading on the trailer.

However, the shoot-thru-hull installation does have its drawbacks.  One,
some loss of sensitivity does occur, even on the best hulls.  This varies
from hull to hull, even from different installations on the same hull.  This
is caused by differences in hull layup and construction.  Two, the angle
of the transducer cannot be adjusted for the best fish arches.  This can
be a problem on some hulls that sit with the bow high when at rest or at
slow trolling speeds.  Follow the procedure listed in the shoot-thru-hull
installation section in this manual to determine if you can satisfactorily
shoot through the hull.

Transducer Assembly and Mounting - All Units
The best way to install this transducer is to loosely assemble all of the
parts first, place the transducer’s bracket against the transom and see if
you can move the transducer so that it’s parallel with the ground.

1. Press the two small plastic ratchets into the sides of the metal bracket

as shown below. Notice there are letters molded into each ratchet.
Place each ratchet into the bracket with the letter “A” aligned with the
dot stamped into the metal bracket. This position sets the transducer’s
coarse angle adjustment for a fourteen (14) degree transom. Most
outboard and stern-drive transoms have a fourteen degree angle.
