Plastic Shim
Standard transom (13° transom angle)— The bracket
is designed for a standard 13° transom angle. The shim
is not needed for this installation. Skip to "Mounting the
Bracket".
Stepped transom and jet boats (3° transom angle)—
Use the shim with the tapered end down. Place the nuts
in the slots in the back of the bracket (see Fig. 6). Snap
the shim into place.
Small aluminum and fiberglass boats (20° transom
angle)—Use the shim with the tapered end up (see Fig.
6). Place the nuts in the slots in the back of the bracket.
Snap the shim into place.
If you are unsure about using the shim, do one of the
following:
• Measure the transom angle of your boat using a di-
gital level or bubble level and protractor. Then fol-
low the instructions above for your transom angle.
• Experiment with the shim by following the instruc-
tions "Mounting the Bracket" and "Checking the
Transducer Angle and Projection".
Mounting the Bracket
1.
Insert the two nuts in the slots in the back of the bracket if
this has not been done (see Fig. 6).
2.
Apply marine sealant to the threads of the two, #10 x 1-3/
4", self-tapping screws to prevent water seepage into the
transom.
3.
Screw the bracket (with the shim if needed) to the hull.
Do not tighten the screws at this time.
Checking the Transducer Angle and Projection
IMPORTANT! Do not position the bow of the sensor
lower than the stern because aeration will occur.
IMPORTANT! Do not position the sensor farther
into the water than necessary to avoid increasing
drag, spray, and water noise and reducing boat
speed.
NO!

1.
Using a straight edge, sight the underside of the sensor
relative to the underside of the hull (see Fig. 7). The stern
of the sensor should be 1–3 mm (1/16–1/8") below the
bow of the sensor or parallel to the bottom of the hull.
2.
Using the vertical adjustment space in the bracket slots,
slide the sensor up or down (see Fig. 5). Be sure the bot-
tom left corner of the sensor projections 3 mm (1/8") be-
low the bottom of the hull.
3.
When you are satisfied with the position of the sensor,
tighten the bracket screws.
NO!
