Installing the Swivel Base

Fastening the Swivel Mount without the Cables 

Running through the Mount

You should complete this procedure only if you are not running 

the power and transducer cables under the mounting surface 

and through the swivel-mount base.

1

Place the base   on the mounting surface, and fasten it 

using the appropriate screws or bolts  .

2

Place the swivel mount on the base, and replace the 10 mm 

M6×1 Phillips screw.

3

Seal the cable pass-through holes with marine sealant.

Preparing to Run Cables under the Mounting Surface

NOTICE

Use pan-head screws or bolts when securing the swivel-mount 

base. Screws or bolts with countersunk heads damage the 

base.

Before you can prepare the swivel-mount base, you must 

choose the location to install the mount and decide whether to 

attach the mount using screws or bolts.

1

Remove the 10 mm M6x1 Phillips screw   and separate the 

swivel mount   from the base  .

2

Orient the swivel base so the pass-through holes   face the 

desired direction.

3

Using the swivel base as a template, mark the pilot hole 

locations  .

4

Mark the cable routing hole  .

5

Using the appropriate drill bit for the hardware, drill the three 

pilot holes.

6

Using a 16 mm (

5

/

8

 in.) drill bit, drill the cable-routing hole.

Fastening the Swivel Mount with the Cables Running 

through the Mount

You should complete this procedure only when running the 

power and transducer cables under the mounting surface and 

through the swivel-mount base.

1

Feed the cables through the 16 mm (

5

/

8

 in.) center hole you 

drilled when preparing to run cables beneath the mounting 

surface.

2

Place the base on the mounting surface.

3

Route the cables through the cable pass-through holes.

4

Loosely fasten the base using the appropriate screws or 

bolts.

5

Place the swivel mount on the base, but do not fasten it.

6

Place the cradle or device into the swivel mount (

Installing 

the Device in the Cradle

, page 4

).

7

Pull out enough slack from the power and transducer cables 

so the mount can fully swivel to the desired positions when 

the cables are connected.

8

Remove the cradle and the swivel mount from the base.

9

Apply marine sealant to the 16 mm (

5

/

8

 in.) center hole and to 

the cable pass-through holes.

10

Securely fasten the base with the appropriate screws or 

bolts.

Place the swivel mount on the base, and fasten it using the 

included 10 mm M6×1 Phillips screw.
