Bedding

CAUTION

: Be sure all surfaces to be bedded are clean and dry.

CAUTION

: When installing the anti-rotation studs, use slip-joint 

pliers placed near the bottom of the stud. Do not use pliers farther 
up, as this will damage the threads.

1. Remove the hull nut (Figure 4,5, 6, or 7).

2. Apply a 2mm (1/16") thick layer of marine sealant to the surface 

of the transducer that will contact the hull/fairing and up the stem. 

The sealant must extend 6mm (1/4") higher than the combined 
thickness of the hull, fairing and backing block (if used), and the 
hull nut. 

This will ensure there is marine sealant in the threads to 

seal the hull and hold the hull nut securely in place.

3. Apply a 2mm (1/16") thick layer of marine sealant around the 

anti-rotation studs 

including the bottom

. This will ensure there is 

marine sealant in the threads to secure the studs in the 
transducer, seal the hull, and hold the nut securely in place.

4. Screw the anti-rotation studs into the holes in the transducer. 

Using slip-joint pliers placed 

near the bottom of the stud

, tighten 

each one in turn. Do not use pliers farther up, as this will damage 
the threads.

5.

Metal hull

—Use the isolation sleeving to cover the transducer 

stem and the two anti-rotation studs. Cut the length of each 
sleeve greater than the thickness of the hull. 

Note that the 

sleeves must not interfere with tightening the nuts.

 Slide the 

larger diameter isolation sleeve over the bedded transducer 
stem. Slide the two remaining isolation sleeves over the bedded 
anti-rotation studs. Slide the sleeves as far down as possible. 
Apply a 2mm (1/16") thick layer of the marine sealant to the 
outside of the three isolation sleeves.

6.

Fairing

—Thread the transducer cable through the fairing. Seat 

the transducer firmly within the recess in the fairing. Apply a 
2mm (1/16") thick layer of marine sealant to the following 
surfaces:

• Fairing that will contact the hull

• Backing block that will contact the hull

• Hull nut that will contact the backing block

• Washers for the anti-rotation studs that will contact the 

backing block
