4. INSTALLATION
40
Note 1:
Do not mount the sensor in an area of
turbulence or bubbles: near water intake or
discharge openings; behind strakes, struts,
fittings, or hull irregularities; behind eroding
paint (an indication of turbulence).
Note 2:
Avoid mounting the sensor where the
boat may be supported during trailering,
launching, hauling, and storage.
Note 3: For single drive boat
, mount on the
starboard side at least 75 mm (3") beyond the
swing radius of the propeller.
Mounting location on single drive boat
Note 4: For twin drive boat
, mount between
the drives.
Installation of bracket
1. Cut out the installation template (en-
closed with transducer) along the dotted
line.
2. At the selected location, position the tem-
plate, so the arrow at the bottom is
aligned with the bottom edge of the tran-
som. Being sure the template is parallel to
the waterline, tape it in place.
Positioning the template
Warning
: Always wear safety goggles
and a dust mask.
3. Using a 4 mm, #23, or 9/64" bit, drill three
holes 22 mm (7/8") deep at the locations
indicated. To prevent drilling too deeply,
wrap masking tape around the bit 22 mm
(7/8") from the point.
Fiberglass hull
: Minimize surface crack-
ing by chamfering the gelcoat. If a cham-
fer bit or countersink bit is not available,
start drilling with a 6mm or 1/4" bit to a
depth of 1 mm (1/16").
4. If you know your transom angle, the
bracket is designed for a standard 13°
transom angle.
11°-18° angle: No shim is required. Skip
to step 3 in "Adjustments".
Other angles: The shim is required. Skip
to step 2 of "Adjustments".
If you do not know the transom angle,
temporarily attach the bracket and sensor
to the transom to determine if the plastic
shim is needed.
5. Using the three #10 x 1-1/4" self-tapping
screws, temporarily screw the bracket to
the hull. DO NOT tighten the screws com-
pletely at this time. Follow the step 1-4 in
"Attaching the sensor to the bracket", be-
fore proceeding with "Adjusting".
Adjustments
1. Using a straight edge, sight the underside
of the sensor relative to the underside of
the hull. 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.
Note:
Do not position the bow of the sen-
sor lower than the stern because aeration
will occur.
2. To adjust the sensor's angle relative to
the hull, use the tapered plastic shim pro-
vided. If the bracket has been temporarily
fastened to the transom, remove it. Key
the shim in place on the back of the brack-
et.
2°-10° transom angle (stepped tran-
som and jet boats)
: Position the shim
with the tapered end down.
