Part 1:

Sonar Controls

1.1 Hand Control

All sonar adjustments are conducted
through the hand control.

1.1.1 Trigger Switch

The trigger switch will move the cursor from
the sonar screen to the selection screen when
adjustments are needed. After adjusting, the trig­ger switch will return the cursor back to the sonar

screen.

1.1.2 Four-way Control Switch

The four-way control switch will move the cursor
up/down, left/right on the sonar screen. By placing
the cursor on a target both horizontal and vertical
measurements are logged in the space noted by the
arrows, center right of screen.When the cursor is
in the selection screen the four-way switch will
move the cursor up/down to the item for adjust­ment. Moving the four-way switch left/right will

make the change.

1.2 Switch Panel

Both the sonar and the hoist are independent
of one another. The sonar has its own on/
off switch and the hoist has its own down/
up switch.

2

1.2.1 Sonar On/Off Switch
The sonar on/off switch is fused with a 10
amp slow blow (MDL) fuse. This fuse is
inline with a fuse on the power supply board
inside the computer box. The power supply
fuse is 7.5 amp fast blow (AGC) for 12 or
24 volt operation.

1.2.2 Hoist Down/Up

To lower the hoist push down on the hoist switch.
If the hoist is hydraulic a green light will glow
when the motor is running and turn off when the
motor stops. The green light is not used with the
lead screw hoist systems. On all systems a red light

will stay on as long as the hoist is down.

1.2.3 Hoist Fuse

On lead screw hoist systems the fuse used is MDL
(slow blow) 3.2 amp. On hydraulic systems use
AGC (fast blow) 1 amp. If the fuse is open the

hoist will not go down.

Lead Screw Hoist

1.3 Selection Screens

There are four selection screens where adjustments
are made. Each adjustment can be viewed as the
sonar runs to maximize target detection. The four
selection screens are titled as; Wesmar 395, Sonar,
Proler and Local. To make an adjustment to the
sonar, trigger once with the hand controller. This
will activate the Wesmar 395 selection screen. To
enter any of the other three selection screens push
up or down on the four way switch until SET UP
is highlighted. Push left or right on the four way
switch for: S = Sonar, P = Proler, L = Local then
trigger with the hand controller. After adjustments
are made, trigger the hand controller to move the

cursor back to the sonar screen.

Wesmar 395 is the rst screen to appear when

triggered with the hand controller. All of the
adjustments are for sonar with the exception of
NEAR P and FAR P, which are gain adjustments

for prole.

RANGE
Sonar range can be increased or decreased by push­ing the four-way switch on the hand controller to
the left or right. Range units; meter, fathom, feet
are selected in selection screen Local.

TILT
Transducer can tilt up +4 degrees above the hori­zontal to –90 degrees straight down. A 0 degree tilt
will center the sound beam horizontally.

CENTER
Move the sector in nine-degree steps around the
screen.

REVERSE
Reverse will change the direction of scan. This
is the recommended method when following fast

moving tagets such as tuna and game sh. There

are two ways to reverse scan.

1. Highlight reverse, push the four-way switch to
the left or right. Each time the four-way switch is
pushed scan will reverse.

2. Highlight reverse, pull the trigger to reverse scan.
Pull the trigger again to highlight reverse then pull
the trigger to reverse. As fast as one can pull the
trigger two times the scan will reverse.

THICK
Thickness will work in sonar screen #1 only. Thick­ness is scanning up and down through the target
or over the bottom. This is an excellent way to see

if there are more sh under the sh schools that

were scanned in the horizontal or to determine the
vertical size distribution of the school. Thickness

can also be used to prole the bottom out in front

to measure depth when entering uncharted

waters.

There are two ways to activate thickness.

1. Highlight thick. Wait for the horizontal scan
to pass through the target. Pull the trigger, the
transducer will stop and start to scan up and down
through the target. The vertical display will show

in the lower right of the screen. As the target

4

moves the thickness mode of operation can

move to follow the target by pushing the four-way
switch to the left or right. Reverse can also be used
to change direction of the vertical scan. To end the
thickness mode pull the trigger twice.

2. Highlight thick. Push the four-way switch to
the left or right. The transducer will stop and start
to scan up and down. Push the four-way switch a
second time to end thickness mode. Note: Entering
thickness mode by using the four-way switch will
disable the ability to change bearing. Bearing can
only be changed when entering thickness by using
the trigger switch.

SECTOR
Select the area to be scanned from full circle; 360
degrees down to 11 degrees.

SPEED
Controls the scanning speed of the sound beam.

Speed 1 is for ne resolution. Speed 4 is for fast up­date. Faster speeds may lose single sh targets.

ZOOM
In Screens 1, 2 and 3 the cursor can be used as
a magnier. By activating zoom the target under
the cursor will magnify for a close inspection.
The perimeter line around the cursor indicates the

magnied area.

NEAR S
Near gain adjustment for sonar. Gain numbers run
from 0 to 100. Regardless of range the near gain
has more control over targets from the center of
the screen to half way out. Adjust for best presen­tation.

FAR S
Far gain adjustment for sonar. Gain numbers run
from 0 to 100. Regardless of range the far gain has
more control over targets from half way to the end
of screen range, or the last half of range selected.
Adjust for best presentation.

NEAR P

Near gain adjustment for prole. Prole gains are

separate from sonar. Gain numbers run from 0 to

5

100. Regardless of range the near gain has more
control over targets from the center of the screen
to half way out. Adjust for best presentation.

FAR P

Far gain adjustment for prole. Gain numbers run

from 0 to 100. Regardless of range the far gain
has more control over targets half way to the end

of the screen range. Prole is frequently used to
prole the bottom. FAR P adjustment is used to

bring bottom markings in strong.

SET UP
Set up provides access to three other selection
screens; SONAR, PROFILE, LOCAL. To acti-

vate one of the three screens rst trigger the hand

controller once. The WESMAR 395 screen will
appear. Move the four-way switch up or down to
set up. Push the four way switch left or right to
highlight the selection screen you want to go to.
Trigger the hand controller for the second time to
view the screen.

By triggering the hand controller the third time will
place the cursor back into the sonar display.

COLOR BARS
There are two color bars, one on top of the other.
The top color bar represents the colors and thresh­old for sonar. The bottom bar represents the colors

and threshold for prole. Adjustments are found in

SONAR and PROFILE.

1.3.2 SONAR

Sonar refers to horizontal scan around the vessel.

This is different from prole where the transducer

scans from side to side beneath the vessel. To

maximize target detection both sonar and prole

each have their own selection screen. Adjustments
can be different from the other. The SS395 will
store the settings and recall them the next time the
system is turned on. However, if there is more than

one application (more then one shery) a record of

the settings should be kept.

RANGE

Same range adjustment under Wesmar 395. For
6

convenience sonar range is repeated.

PULSE
Pulse refers to the transmit pulse or the time the
transmitter is on pushing sound energy into the
water. A long pulse, 100% is best for long-range
detection. Selecting shorter pulse lengths will
increase range resolution separating two targets
close together. As the pulse length is shortened,
near and far gains will need to be increased.

SECTOR
Same sector adjustment found in the last selection
screen, Wesmar 395. For convenience sector is
repeated.

TVG
Time Variable Gain offsets propagation loss as
sound energy moves through the water. A target
at long range will have a small echo than close
to the vessel. In order for this target to mark the
same color at different ranges the receive gain must
increase proportionally with range. Propagation

losses of sound energy will change with frequency,

salinity, and the amount of plankton and algae in

the water. Adjust TVG according to the frequency

of the sonar.

Adjustment:
160kHz set TVG to 400,
span 200 to 600
110kHz set TVG to 600,
span 400 to 800
60kHz set TVG to 800,

span 600 to 1000

Each 100 units will equal 250 ft or 75 meters of
range. A setting of 400 will then equal 1000 ft or

300 meters. When using the blue background a

gray ring will display on the screen equal to the

TVG setting. Targets on the inside of the ring will
be compensated for propagation losses where
targets outside the ring will become stronger as
the vessel approaches until the target cross over

the gray ring.

SPEED

7

Speed will change the scanning speed of the trans­ducer. A speed of one will step the transducer in

1.8 degree steps, where a speed of four will step
in 7.2 degree steps. A speed of one is considered

regular scan with ne resolution where a speed of

four yields a faster scan with lower resolution.

ENHANCE

Enhance is one of three lters. Selections are

from OFF to 5. Enhance will help in target recog­nition of individual targets such as tuna, salmon,

and sports sh. If bottom typing for shrimp, turn

enhance off.

FILTER

Filter is the second of three lters. Filter is used to
lter out unwanted returns and reduce clutter from

the screen. Filter should be turned off when scan­ning for small targets. Use Filter when scanning

for schools of sh and bottom typing

LIMITER

The third of the three lters. The limiter can be ON

or OFF. When ON, interference from any other

sonar/sounder equipment on board will not mark

on the screen. This is accomplished by eliminating
all targets that are not present in two consecutive
transmits at the same range. The limiter is very
effective; however, when scanning for individual
targets it is recommend to turn the limiter OFF.
When the limiter is ON there will be a (?) after

ON to question the operator if this is the correct

setting.

THRESH
Or Threshold. Selections are from 1 to 4. In order
for a target to display on the screen, the echo, after
going through the receiver, must be strong enough
to reach the colors. The colors can be raised or
lowered. Lowering the threshold will display all
targets including weak ones without adjusting
gains. Raising the threshold will remove weak

targets leaving only strong targets on the display.

DELETE
Delete will remove targets colors weak to strong.

8

CLIP
Clip is a color stronger then red. Clip is primarily
used for bottom typing to distinguish between,
rock, sand, or muddy bottom. On hard bottom ad­just gains so bottom just marks in the clip color.

BACK
Back or background is the color behind the targets
on the screen. 1=Black, 2=Blue and 3=White.

Black can be used at night and during the day. At
night the black background emits no light and the
targets stand out in ne detail. For nighttime view­ing it is recommended to lower the brightness of
the text or words on the right of the screen. To dim
the text go to the LOCAL page and increase the
number for TEXT. Blue and White are normally
day time screen. A background color will increase
the contrast making the target much easier to view.
If small targets are of interest try the white back­ground and select 4 to 6 on PALETTE.

PALETTE
Palette deals with target color brightness from blue
to red. When using a low threshold the screen
may by full of blue and green targets. Too much
color on the screen may be distracting; however,
the weak targets are telling the operator something
about the area of search. Palette is a brightness
scale that will dim target colors from weak to
strong. Select a palette number that will dim the
weaker targets without removing them from the
screen. This helps in strong target recognition with
less fatigue to the operator.

1.3.3 PROFILE

Prole scans the transducer from side-to-side un­der the vessel like a pendulum of a clock. Prole

expands bottom coverage not covered by down
sounders. Because the sound beam is narrow
resolution off the bottom is very good. The SS395

in prole will cover the bottom six times that of

a down sounder without the loss of resolution.
To optimize detection prole has its own adjust-

ments.

9

When operating in split screen, SONAR settings
are used when scanning horizontal. When the
transducer moves to prole the PROFILER set­tings will be used.

RANGE

When proling the bottom select a range equal to

twice the depth. This will give full bottom coverage
across the screen.

PULSE
A long transmit pulse, 100% will deliver more
power into the water then a short pulse. A short
pulse has superior range resolution then a long

pulse. When proling for sh just off the bottom

a short pulse should be selected. As the pulse
length is shortened, near and far gains will need
to be increased.

SECTOR

Prole has its own sector sizes with the center mark

straight down.

TVG
Time Variable Gain offsets propagation losses
as sound energy moves through the water. These
losses are compensated by the TVG setting. Losses

are different with different frequencies.

Adjustment:

160kHz set TVG to 300, span 200 to 600
110kHz set TVG to 500, span 400 to 800
60kHz set TVG to 700, span 600 to 1000

SPEED
Speed will change the scanning rate of the trans­ducer as it sweeps over the bottom. For good bot­tom detail use speed 1.

ENHANCE

Enhance is one of three lters. Enhance will help
in target detection of sh and objects on the bottom

small in size.

FILTER

Filter is the second of three lters. Filter is used to
reduce clutter; however, too much lter will lower

10

the probability of detection of small targets.

LIMITER

The third of three lters. The limiter can be ON or

·

OFF. Turning ON the limiter will remove inter-

ference from other sonar/sounder equipment from

the screen. Objects close to the bottom or on the
bottom may not mark with the limiter ON. The
limiter should only be used when large targets are
of interest.

THRESH
Or threshold. Selections are from 1 to 4. If set
too high, only strong targets will be detected. If
the threshold is set low the smallest of echoes will
be detected. For bottom typing a low threshold
setting is desirable.

DELETE
Delete will remove targets colors weak to strong.

CLIP
Clip is a color stronger then red when selected.
When bottom typing make the following settings.
Select the clip color. Lower the threshold to 1.
Turn ENHANCE to OFF. Turn FILTER to 5. When
over hard bottom adjust the near and far gains so
the bottom just marks in the clip color. All other
bottom types will mark in cooler colors.

BACK
Back or background is the color behind the targets
on the screen. 1=Black, 2=Blue and 3=White.

Black can be used at night and during the day. At
night the black background emits no light and the
targets stand out in ne detail. For nighttime view­ing it is recommended to lower the brightness of
the text or words on the right of the screen. To dim
the text go to the LOCAL page and increase the
number for TEXT. Blue and White are normally
day time screen. A background color will increase

the contrast making the target much easier to view.
If small targets are of interest try the white back­ground and select 4 to 6 on PALETTE.

11

PALETTE
Palette is a target brightness control. When ac­tivated screen targets will dim from blue to red.
When using lower thresholds 1 or 2 the screen may
be cluttered with targets. Rather then deleting the
lower colors use PALETTE to lower the brightness
of the weaker targets.

1.3.4 LOCAL

Local are general adjustments that are not changed
to often.

UNITS
Select; feet, meters or fathoms.

LANGUAGE
Select the number that corresponds to the language
of preference.

AUDIO
The hand controller has a built in speaker that will
sound when targets are displayed on thescreen.
For additional volume connect an external ampli-

ed speaker to the audio line output jack on the

computer control unit, see section 3.1.6 for more

information. Audio is only activated after the rst

range ring. This will reduce any audio from noise
that is around the boat. Audio is extended to the
corner of the screen. Two types of audio are avail­able; Fish Alert and Modulation.

FISH ALERT

Fish alert is ideal for purse seining. When sh

schools mark on the screen the alert will sound.
Fish alert is only sensitive to the clip color. Colors

other then clip will not trigger the sh alert. The

size of schools that triggers the alert is determined
by selecting 1 for small schools and 10 for larger

schools. OFF will turn the sh alert off.

MODULATION

Modulation will sound on any size of sh target

and or bottom. By deleting colors or changing
thresholds the sound will follow the change. There
are three selections of the modulation sound, M-1,
M-2 and M-3. Both M-1 and M-2 will have the
sound of the transmit pulse at the beginning of

the receive cycle. Modulation M-1 has a louder
transmit sound then M-2. Modulation M-3 has no

transmit sound, only the sh target will sound and

or bottom will be heard.

VOLUME
Speaker volume selected from 1 to 5.

TEXT
Text will dim all the white lettering and range rings
for night time viewing.

MARKS
Range rings can be turned on or off.

SCREEN

There are four shing sonar screens available.

Screen #1: Full circle sonar
Screen #2: Split Screen sonar on top with bottom

prole on bottom.
Screen #3: Half screen bottom prole only. Can

run with the soundome in the up position
Screen #4: Full screen down sounder.
(Note: Sounder controls Down Sounder settings.)

BRIGHT
Brightness will control the overall intensity of the
display.

TUNING

Adjust frequency for the best target presentation

with minimal noise. This adjustment changes the

frequency of the transmitter and receiver.

ADJUSTMENT:

160kHz, set to 159kHz:
span 156kHz to 162kHz.
110kHz, set to 114kHz:
span 108kHz to 117kHz.
60kHz, set to 60 kHz:
span 57 to 62kHz.

UPDATE
When new programs come available the software
can be installed in the sonar computer board. Select
UPDATE to transfer the new program to the trans­mit receive motor drive board no the hoist assembly.

Can be used to restore the program if need be.

Expansion Box

2.1.1 Hand Controller

The SS395 hand controller can be considered the
sonar consolate where all adjustments are made.

Its location should be easily reached when shing.

The hand controller has a 10ft, 3.0 meter cord with
a connector at the end that mates to the bulkhead
connect.

Would you like to have more than one hand con­troller? Three good locations would be the wheel
house, ying bridge and/or the sh deck. By in­stalling the hand controller expansion box, part
#64.00342.0, and three bulk head connectors part
#64.10342.0 this will give you full sonar control

from three locations.

2.1.2 Bulkhead Connector Panel

The bulkhead connector panel comes with a 10ft
(3 meter) cable with a connector at the end. This
connector will mate to the computer control unit or
expansion box. To install the bulkhead connector,

Bulkhead Connector

make a hole in the instrument panel 1 3/4 inches
(44.5 mm) in diameter. Attach the bulkhead con­nector plate to the instrument pnael using the holes

in the four corners.

2.1.3 Computer Control Unit

The computer control unit is designed to t under

the instrument panel. There are three cables in the
wheelhouse that connect to the computer control
unit. Consider the length of these cables before
selecting a lcoation to mount the computer control

unit.

1. The cable from the bulkhead connector panel is
10ft ( 3 meters) long. it must reach the computer
control unit.

2. The AC power cable from the switch panel is
6 ft (1.8 meters) long. It must reach the computer
control unit.

3. The monitor video cable on most monitors is
normally short. Use an extension VGA cable to
reach the computer control unit if needed. (Exten­sion cable not supplied).

Fasten the computer control unit in place using the

holes in the mounting plate.

2.1.4 Switch Panel

There are two switch panel assemblies, one for
a lead screw hoist and the other for a hydraulic
hoist. Installation is the same for both. The switch
panel does not need to be next to the bulkhead
connector.

Computer Control

Lead Screw Hoist

Switch panels for both the hydraulic hoist and the
lead screw hoist are the same size. They provide
power to the computer control unit through a 6ft
(1.8 meter) cable. This cable must reach the com-

puter control unit. Make a hole 2.5 X 2.5 inches
(63.5 X 63.5 mm). Pass the wires through the
hole and attach the plate by the four corners to the

instrument panel.

2.1.5 Monitor

Specications:

1. VGA, 640 X 480

2. Horizontal Sync. 31.5 kHz

Hydraulic Hoist

15

3. Vertical Sync. 60 Hz

4. Flat Screen or Tube type. Any size.

When selecting a location, keep in mind the fol­lowing:

1. Select a location where the monitor is in full

view when shing.

2. What voltage is available in the wheelhouse to
run the monitor? A converter may be needed to
supply the correct voltage.

3. If there is a chance the monitor might get wet,
install a splash proof or waterproof monitor.

4. If the monitor is in direct sunlight, install a sun­light viewable monitor.

5. If the monitor will be ush mounted, select a

monitor with the on/off and adjustment controls
are on the front.

6. Most monitors come with cables. The video
cable is typically 5 ft (1.5 meters) long. The video
cable connects to the computer control unit. If the
video cable is not long enough use a standard VGA
extension cable.

2.1.6 Audio Line Output

Below the VGA connector on the computer control
unit is a mini jack. This jack will supply the audio

line voltage to an external amplier that is con­nected to the speaker. Speakers with ampliers are

the type used as external speakers on computers.
The mini jack on the SS395 is compatible with the
computer type speakers.

WARNING: Do not connect speakers directly.
In doing so, the audio circuit will be damaged,
not covered by warranty. Only use speakers
with built in amplier like the type used on
computers.

2.2 Seachest
Installation

Checklist:

How much room is needed?
Seachest location.

Seachest Specications.

16

2.2.1 How much room is needed?

There are three measurements needed to determine
the vertical height of the hull unit, seachest and
hoist assembly together.

1. Depth of keel at the location of the seachest.
The overall vertical height is the total length
of the seachest plus the hoist assembly on top. If
the boat has a keel then part of the seachest will
pass through the hull to the bottom of the keel.
This distance will reduce the vertical height needed
inside the boat.

2. Seachest length.
The seachest must be long enough for the
soundom to t inside plus 1 1/2 (38mm) for protec­tion when not in use. This becomes the minimum
length. the minimum length is different for the
following models:
Model: Minimum Length
SS395-E-160 21 in (53.3 cm)
SS395-H-160 24 in (61 cm)
SS395-E-110 22.5 in (57.2 cm)
SS395-H-110 25.5 in (67.8 cm)
SS395-E-60 22.5 in (57.2 cm)
SS395-H-60 29.5 in (74.9 cm)

3. Hoist length
The vertical length is different for the fol­lowing models:
Model: Minimum Length
SS395-E-160 25.75 in (65.5 cm)
SS395-H-160 33 in (83.8 cm)
SS395-E-110 28.75 in (73 cm)
SS395-H-110 33 in (83.8 cm)

SS395-E-60 28.75 in (73 cm)

SS395-H-60 33 in (83.8 cm)

2.2.2 Seachest Location

For the best sonar performance avoid items in
front of the seachest that can create bubbles or
turbulence. Items such as zinc plates, cooling pipes,
sounder housings, water intakes or discharge ports
should NOT be in front of the seachest.

17

Avoid installing the seachest near other sounding

equipment. Down sounders should be behind the

seachest. Other sonars should be on the opposite
side of the keel.

Select a location 1/3 to 1/2 of the ship’s overall
length back from the bow. On lighter boats where
the bow is likely to come out of the water at times,
moving the seachest closer to the half length is
recommended.

Athwart Vessel Location:

1. Installation through the keel is optimum,
center line of vessel roll.

2. Along side the keel and 1/2 in (13 mm)
up from the keel is a very good location, vessel
roll is minimal. The keel also adds strength to the
seachest as it protrudes through the hull. Fair the
seachest to the keel. Alongside the keel will help
keep debris from snagging.

3. If next to the keep is impossible, locate
the seachest within 40 in (1 meter) from the keel.
The bottom of the seachest must extend down to
1/2 in (33mm) up from the keel. Fair the seachest
for-and-aft but not to the hull. If faired to the hull,
bubbles will travel down the taper to the soundome.

To deect debris a plate cut at a 45 degree angle

to the hull should be attached to the leading and

trailing edge of the fairing. The plate will deect

debris and not catch on the seachest.

2.2.3 Seachest Specications

The SS395, depending on the model, will have a 6
in soundome or an 8 in soundome. The size of the

soundome will determine the pipe and the ange
specications. Use one of the following drawings

when fabricating the seachest at the boat yard.
Steel and wooden boats use steel. Aluminum boats

use aluminum. Fiberglass boats use berglass.

Fiberglass seachest with ange can be ordered
from WESMAR. (6 in part #62.04327.0 or 8 in
part #62.04329.0)

6-inch Seachest

1. Use 6-inch schedule 80 steel pipe
(5.761 Id nominal)

2. Length between minimum length (3.2.1)
and 40 in (1.2 m)

18

3. Paint inside with same bottom paint as hull.

8-inch seachest

1. use 8-inch Schedule 80 steel pipe
(7.625 in ID nominal)

2. Length between minimum (3.2.1)
and 40 in (1.2 m)

3. Paint inside with same bottom paint as hull.

2.3 Electrical Hoist
Installation

Note: The SS395 can be ordered with an electrical
hoist or a hydraulic hoist. Section 3.3 will cover
the electrical hoist with 3.6 will cover the hydraulic

hoist.

2.3.1 Calculate Lenth Of Soundome
Tube

There are two electrical hoist systems. One for the
6 in soundome and another for the 8 in soundome.
The difference between the two is the size of the

ange and the total travel.

1. 6 in soundome: measure the length of the
seachest and add 4 in (10 cm)

2. 8 in soundome: measure the length of the
seachest and add 5.5 in (14 cm)

When the proper length of the soundome tube is
determined, measure from the threaded end, mark
the length and cut. File the rough edges.

2.3.2 Check soundome clearance in
side seachest

The soundome should not fit tight inside the

19

seachest. This can place addition strain on the
hoist motor and damage it. Also, if the insides of
the seachest start to rust the dome may jam and
possible damage to the hoist motor may be the

result. A loose tting soundome will be subject to

vibration reducing sonar performance.

The SS395 soundome must t the seachest with a

clearance no greater than 1/16 in (1.6 mm). Both

the 6 in and 8 in ABS soundomes have ns or ribs
on the side of the dome. The ns can be led down
for the correct t.

When checking the soundome, do not handle the
soundome by the soundome cable. Hold the dome

by the neck.

2.3.3 Fasten the soundome to
the soundome tube

1. Thread the jam nut into the soundome.

2. Wrap teon tape around the threads of the soun­dome tube. WARNING: only use Teon tape
on the threads of the soundome tube. Chemical
thread sealant will damage the ABS threads of the
soundome.

3. Run the soundome cable all the way through the
soundome tube, starting from the threaded end.
Have a helper hold the soundome at the same time
rotate the soundome tube. Be careful not to cross
threads. Tighten by hand without tools.

4. Tighten the jam nut using a wrench for a snug

t.

5. To protect the soundome cable from chang on

the end of the soundome tube, a urethane strain
relief is supplied. Cut the urethane strain relief
down one side. Open the cut and push the soun­dome cable into the strain relief. Slide the strain
relief down the cable and into the open end of the

soundome tube.

2.3.4 Asemble Hoist

1. Remove the packing ax from the packing gland

20

on the ange.

2. Run the soundome cable through the ange

following by the soundome tube. Insert the pack-

ing ax one at a time. Use a 1/4 in (6 mm) rod to
push the ax to the bottom of the packing gland.
Rotate the next ax by 90 degrees and push to the
bottom. Do the same for the remaining ax, total

six pieces. Slide the packing gland cap over the
soundome tube. Apply ANTI-SEIZE (supplied) to
the thread posts. Thread the two nuts on each cap
post DO NOT tighten the 7/16 in nuts.

3. Thread the top hoist clamp onto the lead screw

until it is ush with the top.

4. Apply ANTI-SEIZE to the bolts on the saftely
clamp and top hoist clamp. Slide the safetly clamp
over the soundome tube. DO NOT tighten. Push
the soundome tube through the top hoist until 2 in
(51 mm) remain on the other side. Tighten the top
hoist clamp (3/8 in nuts) so the soundome tube is
locked in place.

5. Place safety clamp directly below the top hoist

clamp and tighten bolts.

2.3.5 Attach Hoist to Seachest

1. The 6 in soundome has a FWD stamped on top
of the dome. Locate this mark and make a new
mark on top of the soundome tube in line with the
FWD stamp. This mark will be the reference point
that points to the bow.

2. The 8 in soundome has an AFT stamped and

arrow that points to one of the ns on top of the
soundome. Align the AFT n so it points towards

the stern or back of the boat when the soundome
goes into the seachest. Make a mark on top of the

soundome tube that is in line with the AFT n on

the soundome. This mark will be the reference
point that points to the stern of the boat.

3. Clean the flange surface of both hoist and
seachest. Place the clean neoprene gasket on the
seachest ange. There is no need to grease the gas-

21

ket. Carefully lift the hoist and align the soundome
to the opening of the seachest. Lower the hoist onto
the seachest. Rotate the hoist for easy access to
the TR box. Apply ANTI-SEIZE (supplied) to the
1 inch bolts (supplied). Insert the 1 inch bolt from
the bottom up. Use the lock washers and nuts (sup-

plied) to tighten the hoist ange to the seachest.

4. Align the soundome to the boat, FWD for the
6 in dome and AFT for the 8 in dome. Loosen the
bolts on the top hoist clamp. Rotate the soundome
tube so the mark made in step #1 or #2 are in line.
Tighten the bolts good and tight.

5. Check the soundome inside the seachest. The
hoist is shipped from WESMAR in the up position.
The above procedure will place the soundome 1.5
in (38 mm) inside the seachest. If the boat is out of
the water, check this distance. To make corrections,
loosen the top hoist clamp and push up or down on
the soundome tube for the correct measurement.
Retighten the hoist clamp.

FWD

6. Slide the safety clamp up to the top hoist clamp.
Apply ANTI-SEIZE to the bolts and tighten.

2.4 Wiring

All the cables are tted with connectors. They will

mate at both ends to the computer control unit in
the wheelhouse and to the TR unit located on the

hoist assembly.

NOTE: Starting 1 March 2005 all SS395 computer
control units will operate on 12 to 24V DC. Before

2.5 Operational Checks

2.5.1 Lowering hoist rst time

1. Check to make sure there is enough room beneth
the boat when the soundome goes down.

2. Unplug the hoist motor from the hoist cable.

3. In the wheelhouse push the hoist down on the
switch panel.

4. Plug the hoist motor back into the hoist cable
only enough so the motor runs.

5. Watch the motor as it travels down. It should
stop before the safety clamp comes in contact with
the packing gland. If it looks like the safety clamp
will hit the packing gland unplug the hoist motor.
Rotate the lead screw by hand so the clearance is
no less than .5 in (13 mm) above the packing gland.
Remove the bronze shear pin at the bottom of the
lead screw. Plug the motor back in. The motor will
run and stop. Replace the shear pin.

6. In the wheelhouse verify the red hoist light is on.
This light is a reminder that the hoist is down.

7. In the wheelhouse push the hoist switch up to
raise the soundome. In about 20 seconds the red
hoist lgiht should go out. When the light does go
out, check the position of the top hoist clamp. It
should be up and the motor has stopped running.

2.5.2 Check hoist travel distance

The hoist motor is calibrated at the factory for the
correct travel distance. Lower the hoist and check

24

the distance the soundome travels beneath the keel,
item #4 below.

To make corrections loosen the top hoist clamp and
safety clamp. Move the soundome up or down for

the correct position.

2.5.3 Packing Gland

Tighten the packing gland by rotating the two nuts
hand tight then two complete turns
with a wrench Tighten the second nut agains the

rst nut.

When the boat is back in the water, cycle the hoist
up and down four times. Check the packing gland

for water. It is normal for the packing gland to be
wet but not dripping with water. Retighten the
nuts on the packing gland. WARNING: Do not
tighten the packing gland too tight. A tight packing
gland will hold the soundome tube from moving,
either the fuse will blow or the bronze shear pin
will break.

2.6 Hydraulic Hoist

Installation

The hydraulic hoist will require some

assembly. There are four parts that make up the
complete hoist unit: hoist rack assembly, soundome
tube, hydraulic power pack with hydraulic ram and
soundome. There are two models of hydraulic pow­er packs, DC and AC. The DC unit can be installed
on the hoist rack. The AC, due to its weight, must
be installed on a bulkhead. Bulkhead installation

may require some longer hydraulic lines.

NOTE: The soundome tube has been cut to
match the seachest on board. If there is any
uncertainty on the length contact your dealer
or WESMAR before proceeding with the in-

stallation.

2.6.1 Assemble the soundome tube

1. Remove the packing gland cap and pack ax

25

from inside the packing gland on the ange.

2. Run the soundome tube through the ange

and stop when the tube is half way up the rack
assembly.

3. Insert the packing ax one at a time. Use a
screwdrive to push the ax to the bottom of the
packing gland. Rotate the next ax by 90 degrees

and push to the bottom. Do the same for the
remaining pieces, six in total. Slide the packing
gland cap over the soundome tube and down so

it is touching the ax. Apply ANTI-SEIZE to the
gland cap bolts and thread them in nger tight.

Do not tighten at this time.

4. Slide the tube safety clamp over the soundome
tube.

5. Slide the tube guide clamp over the soundome

tube.

2.6.2 Install the soundome

1. Clean the matting surfaces of the soundome

and soundome tube ange.

2. Run the soundome cable through the ange

o-ring then through the soundome tube so there
is 1 foot 30 cm slack at the dome end.

3. Apply silicone compound to the o-ring. Posi­tion the o- ring in the machined groove on top of
the soundome.

4. Use ANTI-SEIZE and bolt the soundome to

the soundome tube and tighten.

2.6.3 Install the hydraulic ram

1. Remove the top cross plates from the rack as­sembly. Note which plate is connected to which
rack. Make sure the tube guide clamp does not
slip off the soundome tube when removing the
cross plates.
26

Safety Clamp

2. Remove the cable strain relief from the hydraulic
ram end cap.

3. Place the soundome cable in the slot on the
hydraulic end cap. Slide the hydraulic ram inside
the soundome tube. The ram can be disconnected

from the hydraulic power pack by using the quick
disconnect ttings at the end of the hydraulic lines.

Align the soundome cable coming through the end
cap with the rack leg that has the limit switches.
The cable will be to the left and the limit switches
to the right. Push the hydraulic ram in place. Align
the holes in the soundome tube with the holes in the
ram end cap. Slide the tube guide clamp up over the
aligned holes. Bolt all three pieces together. Before

tightening visually draw a line from the packing
gland bolt and the bolt just installed. Rotate the
soundome tube so the two bolts are in line with
one another Tigthen the two bolts. Do not tighten
the packing gland bolts at this time.

4. Place the strain relief grommet around the sound­ome cable. Slide the grommet down the cable until

it ts snuggly into the top of the hydraulic end cap.

Bolt the strain relief plate over the grommet.

5. Push the soundome tube up until the hydraulic
ram shaft goes through the holes in the center of
the cross plates. Thread the castle nut onto the ram
shaft so its snug; at the same time align the holes
through the shaft with the nut. Place a cotter pin

through the hole and lock it in place.

2.6.4 Install hoist assembly

on seachest

Placing the hoist assembly on the seachest will

require the assistance of two or three helpers. Use

a chainfall connected to the overhead to lift the
load.

1. If the hydraulic lines are removed from the

ram end cap, the ttings may leak when the hoist

is lifted up. To reduce leaking, install the safety
clamp around the soundome tube just above the
packing cap and tighten inplace. This will keep the
soundome tube from slipping down when lifting
the hoist.

2. Clean the ange surfaces of the seachest and

hoist. Place the neoprene gasket on the seachest

ange.

3. Lift the hoist assembly and set it on top of

the seachest. Rotate the ange to coincide with

the hoist power pack and limit switches for easy
maintenance.

Alignment considerations:
a) Only DC power pack can be
installed on the hoist rack. The rack opposite the
limited switches is the only rack leg the power pack
can be attached to.
b) The AC power pack must be
installed on a bulkhead. The DC power pack can
also be installed on a bulkhead and not on the
rack. Rotate the hoist so the rack leg with the limit
switches is adjacent to the bulkhead that has the
power pack. This will avoid crossing the hydraulic
lines.

4. Bolt the hoist ange to the seachest. Apply

ANTI-SEIZE on the bolt threads. Insert the bolts
from the bottom up. Use the lock washer and nuts
and tighten in place.

5. Tighten the packing gland cap bolts nger tight.

Use wrench and tighten each bolt one full turn,
repeat for a total of two turns.
NOTE: When the vessel is back in the water, cycle
the hoist up and down four times. Check the pack­ing gland for water. It is normal for the packing
gland to weep but not drip. Tighten if necessary.

2.6.5 Install hydraulic power pack

1. Install the DC power pack on the rack leg op­posite the leg with the limit switches. About half
way up on the leg are two holes where the DC
mounting bracket will bolt to. Use ANTI-SEIZE
and tighten in place. Connect the hydraulic lines
to the cylinder.

2. Install the AC power pack to the bulkhead. Use
the mounting bracket attached to the motor. Gener­ally taped standoffs are welded to the bulkhead and
the motor will bolt to them. The hydraulic lines will

28

need to be lengthened. Make sure there is enough
slack in the lines for up and down travel. Connect
the hydraulic lines to the cylinder.

3. After the hydraulic lines are connected make
sure they are free to travel and no change to catch
on nonmoving part. The soundome cable must also
be free to travel and not catch on any nomoving
part.

4. Install the vent screw in the reservoir. In order to
ship the hydraulic power pack full of oil the vent
screw was replaced with non-venting screw. This

non-venting screw must be removed and replaced

with the supplied venting tape.

2.7 Wiring, DC

Hydraulic Hoist

The DC hydraulic hoist is a stand alone sys-

tem that does not require power from the sonar. It

will operate on its own. The hydraulic power pack
is avialable in 12V, DC and 24V DC. Wiring is dif­ferent between the two voltage systems. Check the

voltage of the hydraulic pack unit before wiring.

DC Power Pack

DC Power Pack Mounting

Pack Leg Opposite Limit Switches

2.7.1 DC hoist board wiring

1. The DC hoist board is enclosed in its own alumi­num box. The DC hoist board will work on both
12V hydraulic power pack units and 24V hydraulic
power pack units.

2. Hoist control cable, PN: 78.10015.0
The hoist control cable is 25 feet (7.6 meters) long.
One end is terminated witha six pin connector, the
other end is terminated with terminal lugs. The
connector end will mate with the connector on
the switch panel in the wheelhouse. the other end

will go through a strain relief tting on the hoist

control box and connect to termintal TB1, number
to number.
If a longer hoist control cable is needed, hoist ex­tension cables are avialable in 25 feet (7.6 meter)

29

lengths, PN: 78.10015.1

3. Hoist board voltage
Voltage to the hoist board must be the same as the
voltage for the hydraulic power pack. This voltage
powers the solenoid valve, the big relay on the
DC motor, the up/down relays on the hoist board
and the red and green lights on the switch panel
in the wheelhouse. The hoist board is fused with
a 5A slow blow fuse. Run ships power through a

strain relief tting on the hoist box and connect

the battery negative to terminal #31 and battery
positive to terminal #30. Use the correct wire size

to carry 5 amps over the distance from battery to
hoist board.

4. Solenoid valve wiring
The large relay on the DC motor is activated by
the same voltage that operates the solenoid valve.
To simplify wiring the relay is pre-wired into the
solenoid valve. From the solenoid valve there is
a pre-wired cable with numbered lugs at the end.
Pass the cable through a strain relief on the bot­tom of the hoist box. Connect the wires to TB2,
number to number.

5. Limit switch up/down wiring
Located on the hoists are two limit switches that
will stop the hoist at its up and down limits. Both
switches are pre-wired and numbered at WES­MAR. Run the limit switch wires through a strain
relief on the hoist box. Connect the wires to TB2,
number to number.

12 Volt Wiring:

+12V

12V Ground

24 Volt Wiring:

6. DC motor wiring
The hydraulic power pack is available in 12V

and 24V. Conrm the voltage of your unit before

wiring. The 12V motor will draw 65 amps under
normal load. The 24 volt motor will draw 40 amps
under normal load. The amperage will go up if
resistance in hoisting increases. Fuse the 12 volt
motor for 130 to 140 amps. Fuse the 24 volts for
55 to 60 amps. Select a wire guage appropriate for
the load. The hoist takes less than ten seconds to
go up or down so the cycle is very short before it
turns off. Wire as pictured to the left.

2.8 Wiring, AC

hydraulic hoist

The AC wiring hoist is a stand-alone sys-

tem that does not require power from the sonar to

operate. It will operate independent from the sonar.
The hydraulic power pack is available 110V AC
signle phase and 220V AC single phase. Wiring is

the same for both systems.

2.8.1 AC hoist board wiring

1. The AC hoist board is enclosed in its own alu­minum box. Before wiring, check the AC voltage
of the board. Next to transoformer T1 there will
be one or two jumpers installed. One jumper is for
220V AC and two jumpers are for the 110V AC
NOTE: Use a 30 amp slow blow fuse for 110V AC
and a 20 amp slow blow fuse for 220V AC.

2. Hoist board voltage.
Voltage to the hoist board is the same voltage that
will power the motor and the solenoid valve on
the hydraulic power pack. Run ships AC power

through one of the strain relief ttings on the hoist

box and connect the wires to TB3. Use wire size
capable to handle a one horsepower motor.

3. Hoist control cable, PN: 78.10015.0
The hoist cable is 25 feet (7.6 meters) long. One
end is terminated with a six pin connector, the other
end is terminated with terminal lugs. The connector
will mate with the connector on the switch panel
in the wheelhouse. The other end will go through

one of the small strain relief ttings on the hoist

control box. Connect each number wire to the same
numbered terminal on TB1.
If longer hoist control cable is needed, hoist exten­sion cables are available in 25 feet (7.6 meters) in
length, PN: 78.10015.1.

4. Solenoid valve wiring

31

The solenoid valve is pre-wired with terminal lugs
at the ends. Run the solenoid cable through one of

the strain relief ttings on the hoist box. Connec

the wires to TB2, number to number.

5. Limit switch up/down wiring:
There are two limit switches on the hoist rack that
will stop the hoist at the travel limits. Both swtiches
are pre-wired with terminal lugs at the ends. Run
the limit switch wires through on of the strain relief

ttings on the hoist box. Connect the wires to TB4,

number to number.

2.9 Operation check,

hydraulic hoist, DC & AC

2.9.1 Lowering hoist rst time

1. Check to make sure there is enough room be­neath the boat before lowering the soundome. Total
travel is 18 inches, 45.5cm. Outside the seachest

16.5 inches, 42cm.

2. Make sure the hoist switch is in the up posi­tion.

3. Disconnect the upper hoist limit switch wire
labeled #27 located on, TB2 for DC motors or TB4
for AC motors. Once this wire is disconnected the
hoist will only move down when powered.

4. Disconnect the hoist down limit switch wire la­beled #1 located on, TB1 for DC motors and TB1
for AC motors. Once this wire is disconnected
the hoist will not move when the hoist switch
in the wheelhouse is pushed down to lower the
soundome.

5. 1. The hoist will lower. The hoist should stop
before the safty clamp comes in contact with the
packing gland. If it looks like the safety clamp will
come in contact with the packing gland remove
the wire immediately. Tap the wire on terminal #1
for short movements until the hoist stops. The top
clamp should stop no less then 0.5 inches, 13mm

32

above the packing gland.

Adjustment - Move the lower limit switch up on
the hoist rack so the top clamp is 0.5 inch, 13mm
to 1.0 inch, 25.5mm above the packing gland

6. Lift up the soundome - Push the hoist switch up
in the wheelhouse. Touch the wire labeled #27 to
terminal #27. The hoist will start to go up. The
hoist should go up and stop and the motor turn
off.

Adjustment - If the motor keeps running when the
hoist has stopped in the up position the top limit
switch must be lowered. Lower the limit switch
so the hoist will stop 0.5 inch, 13mm before the
mechanical stop.

7. Connect the wires back to terminal #27 and
#1.

2.9.2 Check hoist soundome travel.

1. Lower the soundome, push the hoist switch down
in the wheelhouse.

2. Measure the distance from the bottom of the
seachest to the bottom of the soundome under the
boat. The distance should be 16.5 inch, 42mm to

15.5 inch, 39mm.

2.9.3 Packing gland

1. Tighten the packing gland by rotating the two
nuts hand tight then two complete turns with a

wrench. Tighten the second nut against the rst

nut to lock.

2. When the boat is back in the water cycle the hoist
up and down four times. Check the packing gland
for water. It is normal for the packing gland to be
wet but not dripping with water.

3. Retighten the nuts if water drips after cycling
the hoist. WARNING: Do not tighten the packing
gland too tight. A tight packing gland will hold
the soundome tube from moving and may trip the

33

circuit breaker or damage to the electric motor.

4. From time to time inspect the packing gland.

Tighten if needed.

2.10 Hydraulic Hoist Trou­bleshooting

1. Up and down are reversed:
a. Solenoid valve is wire opposite.
b. Hydraulic lines are reversed.

2. Hoist motor runs, green light on, but will not
raise or lower.
a. Solenoid valve stuck.
b. Check solenoid wiring.
c. Fluid level in reservoir is too low.
d. Packing gland cap is too tight.
e. Hoist rack is bent.
f. Obstruction in seachest.
g. Reservoir is not vented.

3. Hoist motor continues to run, green light on,
hoist did go up & down.
a. Limit switch arm not triggering.
b. Soundome tube not traveling all the
way.
c. Broken wires to limit switches.

d.Reservoir low on uid.

4. Soundome tube will not stay up.
a. Dirty check valve.
b. Leak in hydraulic lines.
c. Leak in hydraulic cylinder.

34

2.11 Hydraulic
Maintenance

Monthly checks:

1. Oil Reservoir - Fluid level should be at the
venting plug with the hoist in the up position.

Oil, Chevron automatic transmission uid,
“Dexron II” or equivalent.

2. Packing gland - Little water should weep
from the packing. It should not drip. If there is
too much water coming from the packing gland
tighten each of the cap bolts one full turn. Run
the hoist up and down and check for water. If
the packing gland cap has bottomed out, add one
new layer of packing, Wesmar part #09.00749.0

3. Check all wiring and hydraulic lines that may
catch or snag when the hoist is moving
