Installation:

NOTE: If you are installing the transducer with NO fairing, 
disregard all references to a fairing and backing block. Skip to 
“Hole Drilling” on page 3.

Cutting the Fairing

CAUTION:

 The arrow on the fairing points forward toward the 

bow when installed. Be sure to orient the fairing on the band saw, 
so the angle cut matches the intended side of the hull and not the 
mirror image.

CAUTION

: Shape the fairing to the hull as precisely as possible. If 

there are gaps between the fairing and the hull near the ends, cut 
a new fairing. Over tightening the rods to minimize gaps may 
crack the transducer and/or crush the fairing.

1.

Metal hull

—The holes for the anti-rotation studs must be 

enlarged to accommodate the isolation sleeving. Using a 10mm 
(3/8") drill bit, enlarge the two holes in the fairing.

2. Measure the deadrise angle of the hull at the selected mounting 

location using an angle finder or a digital level (Figure 3).

3. Tilt the band saw table to the measured angle and secure the 

cutting fence (Figure 4).

4. Fasten the fairing to the center of the block of wood using the 

four corner holes and No. 8 screws.

5. Place the fairing on the table so the cutting guide rests against 

the fence. The arrow will be pointing 

toward

 you for installation 

on the starboard side of the boat or 

away

 from you for 

installation on the port side (Figure 5).

6. Adjust the cutting fence, so the fairing will be cut in about two 

equal parts (Figure 3). 

The section that will become the fairing 

must be a minimum of 7mm (9/32") at its thinnest dimension

This number corresponds to the flange on the fairing.

7. Recheck steps 1 through 5. Then cut the fairing.
8.

Check the fit of the fairing by placing it against the hull, 
being sure it is parallel to the centerline of the boat (keel)

Hold the fairing on the ends and try to rock it back and forth. 
Shape the fairing to the hull as precisely as possible with a rasp 
or power tool until it no longer rocks.

9. Remove the fairing from the block of wood.
10.Use the remaining section of the fairing with the cutting guide 

as the backing block.

Hole Drilling

Cored fiberglass hull—Follow separate instructions on page 6.

1. Locate and drill the holes for the transducer stem and anti-rotation 

studs, using the fairing or the provided template on page 8 as a 
guide (Figure 4, 5, 6, or 7). Align the fairing or template parallel to 
the centerline of the boat (keel).
• Drill 3mm (1/8") pilot holes for the transducer stem and the 

two anti-rotation studs.

• Using the appropriate drill bits/hole saw, drill the holes for 

the transducer stem and the two anti-rotation studs.

Fairing

—Drill through the holes in the fairing to be sure the 

holes are drilled 

perpendicular to the waterline 

and not at 

the angle of the hull.

NO Fairing

—Be sure to drill the holes perpendicular to the 

hull.

2. Sand and clean the area around the holes, inside and outside, 

to ensure the marine sealant will adhere properly to the hull. If 
there is any petroleum residue inside the hull, remove it with 
either a mild household detergent or a weak solvent (alcohol) 
before sanding.

Metal hull

—Remove all burrs with a file and sandpaper.
