Installing the Transom-Mount Hardware
NOTICE
If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
1
Place the transducer mount so the top of the transducer is even with or up to 12.7 mm (
1
/
2
in.) above the
bottom edge of the transom.
2
Using the transom mount as a template, mark the location of the pilot holes.
3
Wrap a piece of tape around a 4 mm (
5
/
32
in.) bit at 19 mm (
7
/
10
in.) from the point of the bit, to avoid drilling
the pilot holes too deep.
4
If you are installing the bracket on fiberglass, place a piece of tape over the pilot-hole location to reduce
cracking of the gel coat.
5
Using the 4 mm (
5
/
32
in.) bit, drill the pilot holes approximately 19 mm (
3
/
4
in.) deep at the marked locations.
6
Apply marine sealant to the included 20 mm screws.
7
Using the four 20 mm screws
, attach the transducer mount to the transom.
NOTICE
When mounting the transducer, be sure to secure all four corners of the mount with the included screws
.
This is especially important on vessels that operate at high speeds. If only the top or bottom holes are used,
the bracket may bend or break when the vessel moves at high speeds, dislodging the transducer.
8
If you must route the cable through the transom, choose a pilot-hole location well above the waterline and
mark it.
9
If you marked a pilot hole in step 8, use a 32 mm (1
1
/
4
in.) hole saw to drill a pass-through hole completely
through the transom.
10
Route the transducer cable to the sonar module:
•
If you are routing the cable using a pass-through hole, push it through the hole you drilled in step 9.
•
If you are not routing the cable using a pass-through hole, route the cable up and over the top of the
transom .
You should avoid routing the cable close to electrical wires or other sources of electrical interference.
