1 Position the transducer mount so the center of the bottom À of the transducer is level with the bottom edge of the transom and is parallel to the water line. 2 Align the transducer parallel to the water line , and mark the Á center location of the two outer holes and the center hole of the transducer mount. 3 Wrap (19/32 a piece of tape around a 4 mm (5/32 in.) from the point of the bit, to avoid in.) bit at 15 mm 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 U15simngmth(1e9/432minm.)(d5/e3e2 pina.)t bit, the drill the pilot holes marked locations. approximately 6 Apply marine sealant to the included 20 mm screws, and attach the transducer assembly to the transom. NOTE: The third screw in the lower center screw hole stabilizes the mount. 12If you marked a pilot hole in step 9, choose the appropriate drill bit and drill a pass-through hole completely through the transom: • If you have the 4-pin cable, use a 16 mm (5/8 in.) drill bit. • If you have the 8-pin cable or the 12-pin cable, use a 25 mm (1 in.) drill bit. 13Route the transducer cable to the sounder: • If you are routing the cable using a pass-through hole, feed it through the hole you drilled in step 12, and install the cable-entry cover (Installing the Cable-Entry Cover, Ã page 2). • If you are not routing the cable using a pass-through hole, route the cable up and over the top of the transom . Å Avoid routing the cable close to electrical wires or other sources of electrical interference. Installing the Cable-Entry Cover If you routed the cable through the transom after you installed the transducer, you should install the cable-entry cover to keep water from entering your boat. 1 Place the cable-entry cover over the hole and the cable, À with the opening pointing downward, and mark the location of the two pilot holes. 2 Remove the cable-entry cover, and, using a bit, drill the pilot holes approximately 10 mm 3.2 (3/8 mm in.) (1/8 in.) deep. 3 Fill the pass-through hole with marine sealant so it covers the cable completely and there is excess sealant around the hole and the cable. 4 Place the cable-entry cover over the hole and the cable, with the opening pointing downward. 5 Apply marine sealant to the included 12 mm M4 screws, and attach the cable-entry cover to the transom. 6 Wipe away all excess marine sealant. Testing the Installation 7 If you must route the cable through the transom, choose a pilot-hole location well above the waterline and mark it. Ã 8 Place a cable clamp on the transducer cable , Ä approximately one third of the distance between the transducer and the top of the transom or the pilot hole. 9 Mark the pilot-hole location for the cable clamp, and using a 3.2 (3/8 mm (1/8 in.) in.) deep. bit, drill a pilot hole approximately 10 mm 10Apply marine sealant to the included 12 mm screw, and attach the cable clamp to the transom. 11Repeat steps 8 through 10 to install the other cable clamp approximately two thirds of the distance between the transducer and the top of the transom or the pilot hole. NOTICE You should check your boat for leaks before you leave it in the water for an extended period of time. Because water is necessary to carry the sonar signal, the transducer must be in the water to work properly. You cannot get a depth or distance reading when out of the water. When you place your boat in the water, check for leaks around any screw holes that were added below the water line. Testing the Transom-Mount Transducer Installation NOTICE When adjusting the depth of the transducer, make the adjustments in small increments. Placing the transducer too deep can adversely affect the performance of the boat and put the transducer at risk of striking underwater objects. Test the transom-mount transducer installation in open water free of obstacles. Pay attention to your surroundings as you test the transducer. 1 With the boat in the water, turn on the chartplotter. 2

1
Position the transducer mount
À
so the center of the bottom
of the transducer is level with the bottom edge of the transom
and is parallel to the water line.
2
Align the transducer parallel to the water line
Á
, and mark the
center location of the two outer holes and the center hole of
the transducer mount.
3
Wrap a piece of tape around a 4 mm (
5
/
32
in.) bit at 15 mm
(
19
/
32
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
15 mm (
19
/
32
in.) deep at the marked locations.
6
Apply marine sealant to the included 20 mm screws, and
attach the transducer assembly to the transom.
NOTE:
The third screw in the lower center screw hole
stabilizes the mount.
7
If you must route the cable through the transom, choose a
pilot-hole location well above the waterline
Ã
and mark it.
8
Place a cable clamp on the transducer cable
Ä
,
approximately one third of the distance between the
transducer and the top of the transom or the pilot hole.
9
Mark the pilot-hole location for the cable clamp, and using a
3.2 mm (
1
/
8
in.) bit, drill a pilot hole approximately 10 mm
(
3
/
8
in.) deep.
10
Apply marine sealant to the included 12 mm screw, and
attach the cable clamp to the transom.
11
Repeat steps 8 through 10 to install the other cable clamp
approximately two thirds of the distance between the
transducer and the top of the transom or the pilot hole.
12
If you marked a pilot hole in step 9, choose the appropriate
drill bit and drill a pass-through hole completely through the
transom:
•
If you have the 4-pin cable, use a 16 mm (
5
/
8
in.) drill bit.
•
If you have the 8-pin cable or the 12-pin cable, use a
25 mm (1 in.) drill bit.
13
Route the transducer cable to the sounder:
•
If you are routing the cable using a pass-through hole,
feed it through the hole you drilled in step 12, and install
the cable-entry cover
Ã
(
Installing the Cable-Entry Cover
,

).
•
If you are not routing the cable using a pass-through hole,
route the cable up and over the top of the transom
Å
.
Avoid routing the cable close to electrical wires or other
sources of electrical interference.
Installing the Cable-Entry Cover
If you routed the cable through the transom after you installed
the transducer, you should install the cable-entry cover to keep
water from entering your boat.
1
Place the cable-entry cover
À
over the hole and the cable,
with the opening pointing downward, and mark the location of
the two pilot holes.
2
Remove the cable-entry cover, and, using a 3.2 mm (
1
/
8
in.)
bit, drill the pilot holes approximately 10 mm (
3
/
8
in.) deep.
3
Fill the pass-through hole with marine sealant so it covers the
cable completely and there is excess sealant around the hole
and the cable.
4
Place the cable-entry cover over the hole and the cable, with
the opening pointing downward.
5
Apply marine sealant to the included 12 mm M4 screws, and
attach the cable-entry cover to the transom.
6
Wipe away all excess marine sealant.
