Testing The Installation - Garmin STRIKER VIVID Owner's Manual

Installing the Transom-Mount Hardware
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.
The cables connected to the transducer should not be cut,
because cutting the transducer cables voids your warranty.

installation location (Mounting Consideration, page
the bottom corner of the template on the edge of the
transom.
3
Mark the center location of the two holes of the template.
4
Remove the template from the transom.
5
Wrap a piece of tape around a 4 mm (

( / in.) from the point of the bit, to avoid drilling the pilot

holes too deep.

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.

Route the cable under the transom mount cable hook.

If you must route the cable through the transom, choose a
pilot-hole location well above the waterline and mark it.
11
Place a cable clamp on the transducer cable, approximately
halfway between the transducer and the top of the transom or
the pass-through pilot hole.

Mark the pilot-hole location for the cable clamp, and using a

If you marked a pilot hole in step 7, choose the appropriate
drill bit to drill a pass-through hole completely through the
transom:
• If you have the 4-pin cable, use a 16 mm (
• If you have the 8-pin cable, use a 25 mm (1 in.) drill bit.
15
Route the transducer cable to the sounder:
• If you are routing the cable using a pass-through hole,
push it through the pass-through hole, and install the
cable-entry cover
page 2).
• If you are not routing the cable using a pass-through hole,
1), place
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.
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
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 (
bit, drill the pilot holes approximately 10 mm (
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

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
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.
