Installing

CAUTION

: Do not over-tighten the nuts possibly damaging the 

transducer or fairing.

1. From outside the hull, thread the cable through the mounting 

hole (Figure 4, 5, 6, or 7).

2. Push the stem of the transducer and the anti-rotation studs 

through the hull.

3. From inside the hull:

Fairing

—Slide the backing block and the hull nut onto the 

cable. Seat the backing block firmly against the hull. Screw 
the hull nut in place and tighten it with slip-joint pliers. 

Do not 

over-tighten

. With the bedded side down, slide one washer 

and nut onto each anti-rotation stud. Tighten the nuts 

one full 

turn only

 with slip-joint pliers. 

Do not over-tighten

.

Cored fiberglass hull

Do not

 over-tighten crushing the hull.

Wood hull

—Allow for the wood to swell before tightening.

Metal hull

—Be sure the isolation sleeves are between the 

transducer stem/studs and the hull. 

The isolation sleeves 

must be below the nuts to prevent the sleeves from interfering 
with tightening the nuts.

 Trim the sleeves if necessary.

NO fairing

—Slide the rubbery washer and hull nut onto the 

cable. Seat the rubbery washer firmly against the hull. 
Screw the hull nut in place and tighten it with slip-joint 
pliers. 

Do not over-tighten

. Slide the rubbery washer, metal 

washer, and nut onto each anti-rotation stud. Seat the 
rubbery washer firmly against the hull. Tighten the nuts 

one 

full turn only

 with slip-joint pliers. 

Do not over-tighten

.

Cored fiberglass hull

Do not

 over-tighten crushing the hull.

Wood hull

—Allow for the wood to swell before tightening.

Metal hull

—Be sure the isolation sleeves are between the 

transducer stem/studs and the hull. 

The isolation sleeves 

must be below the nuts to prevent the sleeves from 
interfering with tightening the nuts.

 Trim the sleeves if 

necessary.

4.

Fairing

—When the boat is underway, especially at high 

speeds, water will enter any gaps and push against the fairing 
with considerable force, possibly rotating it. Fill any gaps 
between the fairing and the hull with marine sealant. 

If there is 

any gap greater than 1.5mm (1/16"), replace the fairing.

5. Remove any excess marine sealant on the outside of the hull, 

transducer, and fairing if used to ensure smooth water flow 
under the transducer.
