2-1 Positioning a through hull transducer

This transducer will be ﬁ tted in a hole drilled in the bottom of the boat. Select a position for the transducer that has a smooth ﬂ ow of clear water over the transducer surface at all times. This means that the transducer should be ahead of any keel, hull projections, hull openings, paddle wheel transducers, propellers or propeller wash. If the bottom of the boat is painted and the boat has been used, do not mount the transducer where the paint is eroded (an indication of turbulence).

In addition, position the transducer:

as close to the middle line of the hull as possible and as deep as possible where the deadrise angle is small with sufﬁ cient space inside the hull for access and wiring so that it will not interfere with launching

or retrieving the boat Ideally a depth transducer should be ﬁ tted so that its axis is vertical, however it can be up to 15° off vertical.

Suitable locations for transducer

2-2 Installing a through hull transducer

1 Select a suitable position for the

transducer (see section 2-1). If the hull panel is too thin or the panel

might not be strong enough, consider

ﬁ tting a reinforcing pad on the inside of

the hull. 2 Find the hole size required for the

transducer from the table above. Drill or

cut the hole in the hull. The hole must be

perpendicular to the hull surface. 3 For an insertable transducer:

i remove the locking nut or pin

rom the ﬁ tting

ii pull the transducer out from the

hull ﬁ tting

iii unscrew the nut from the hull ﬁ tting.

For a ﬁ xed transducer:

i unscrew the nut from the hull ﬁ tting

ii hold the nut just inside the hole

in the hull

iii feed most of the transducer cable

through the hole in the hull (from the outside) and through the nut.

4 Apply a thick layer of ﬂ exible bedding

compound (such as Sikaﬂ ex) to the

Remove locking nut or pin

hull ﬁ tting on the inside face of the ﬂ ange

and on the exterior threads where they

pass through the hull. 5 Insert the hull ﬁ tting into the hull from

outside. For a speed/temperature

transducer, rotate the ﬁ tting until the arrow

on the outside lip points forward to within 5°. 6 Fit and tighten the nut on the hull ﬁ tting.

For a plastic ﬁ tting, hand-tighten the nut

and do not over tighten. For a bronze

ﬁ tting, tighten with slip-joint pliers. Tighten the nut until excess bedding

compound is squeezed out from under

the nut and the face of the hull ﬁ tting.

Remove the excess bedding compound. 7 For a speed/temperature transducer,

check that the arrow on the hull ﬁ tting still

points forward. 8 For an insertable transducer:

i ensure there is a thin layer of silicone

grease or O-ring lubricant on the transducer O-rings

ii insert the transducer back into the hull

ﬁ tting, rotating the transducer so that the arrow on the transducer mates with the notch on the ﬁ tting

iii replace the locking nut or pin. 9 Wait for the bedding compound to dry. 10 Before leaving the boat unattended,

check that there is no water ingress

from around the transducer.

3 In-hull depth transducer

One in-hull transducer is available, a depth transducer.

Part # - Europe 27948 Part # - Rest of World AA002161 Material Plastic Connector RCA phono Max. hull thickness ¾" (20 mm) Cable length 26.2 ft (8 m)

Caution

In-hull depth transducers are only suitable for solid GRP hulls up to ¾" (20 mm) thick, without air pockets, beads or voids. They are not suitable for wooden, metal or sandwich hulls. Compared to other types of transducer, in-hull depth transducers generally have lower performance because power is absorbed in the hull.

3-1 Positioning an in-hull transducer

This transducer will be glued to the inside of the bottom of the boat. Select a position for the transducer that has a smooth ﬂ ow of clear water under the transducer at all times. This means that the transducer should be ahead of any keel, hull projections, hull openings, paddle wheel transducers, propellers or propeller wash. If the bottom of the boat is painted and the boat has been used, do not mount the transducer where the paint is eroded (an indication of turbulence).

In addition, position the transducer:

as close to the middle line of the hull as

possible and as deep as possible

with sufﬁ cient space inside the hull for

access and wiring

where the inside surface of the hull is ﬂ at and

smooth and there will be no gaps between

the face of the transducer and the hull.

The face of the transducer is angled. When ﬁ tting the transducer, rotate the transducer so that the axis of the transducer is as close to vertical as possible.

Ideally the transducer should be rotated so that its axis is vertical, however it can be up to 15° off vertical.

3-2 Installing an in-hull depth transducer

1 Select a suitable position for the

transducer and establish how the

transducer should be rotated so that the

axis is as vertical as possible (see section

2-1). 2 Test the transducer at this position with the boat in the water before mounting it permanently:

i Partially ﬁ ll a thin plastic bag with

water, place the transducer inside and

close it tightly around the cable with a tie-wrap. ii Install the depth instrument as

described in the instrument’s

Installation and Operation manual. iii Wet the surface of the hull and press

the transducer against the inside of

the hull where you plan to mount the

transducer. iv Check that the instrument measures

depth correctly and consistently, up

to the maximum depth speciﬁ ed for

the instrument. If necessary, move the

bag around the hull to ﬁ nd the best

position.

3 Choose an adhesive or sealant to glue

the transducer to the hull. Hard epoxies transmit the transducer signals best but temperature changes and hull ﬂ exing can cause delamination. As a compromise, use a viscous slow cure, fairly rigid epoxy or Sikaﬂ ex 252 sealant.

4 Ensure the inside of the hull where the

transducer will be mounted is ﬂ at.

Clean, degrease and dry:

the inside of the hull where the

transducer will be mounted

the sloping face of the transducer

5 Fit the transducer:

i Apply the epoxy or sealant to the

middle of the transducer face. ii Press the transducer into place on the hull. iii Twist the transducer back and forth to

expel any trapped air and to expel as

much glue as possible from the joint.

The ﬁ nished joint should be as thin as

possible and not contain any air bubbles. Leave the transducer rotated to the

correct angle. iv Temporarily secure the transducer in

place with tape and wait for the glue

to cure for 24 hours.
