1.   Assemble   the   stainless   steel   brackets   to   the   transducer   using   the

hardware  furnished.  Do  not  tighten  until  final  adjustments  are  made.

2.   Place   assembly   on   transom   at   selected

location   with   the   front   of   the   transducer

extending   1/2"   to   5/8"   below   the   bottom   of

the   boat   and   with   the   front   part   against   the

transom.   The   least   amount   that   the

transducer   extends   below   the   bottom   is

desired.   If   too   low,   spray   and   turbulence   will

occur.

3.   With  transducer  in  place,  mark  location  of  slotted  holes  in  brackets.

4.   Drill   in   center   of   slot   outline   with   a   9/64"   (3.5mm)   drill,   3/4"   (19mm)

deep.

5.   Fasten  the  transducer  to  the  transom  using  the  #10  x  3/4  screws.

6.   Before   final   tightening   the   4   screws   holding   the   brackets   to   the

transducer,  tip  the  rear  edge  down  approximately  1/8"  as  shown.

7.   Tighten   all   screws.   CAUTION.   DO   NOT   use   any

thread   locking   compound   on   the   screws.   Most

products   such   as   LOCTITE   contain   chemicals   that

attack   and   weaken   plastics.   IMPORTANT.   There

should   be   no   gap   between   the   brackets   and   the

transducer.   A   wide   space   between   these   parts   will

cause   stress   on   the   transducer   mounting   ears   and   result   in   breakage

with  time.

8.   In  running  the  cable  to  the  sounder,  avoid  proximity  to  other  wiring  on

the   boat,   particularly   ignition   and   alternator   cables.   They   can   be   a

source  of  noise  on  the  sounder  display.

Puck  Style  Transducers

There  are  two  ways  in  which  the  puck  style  transducer  can  be  mounted.  It

can  be  mounted  in-­hull  or  on  an  electric  trolling  motor.

 

In-­Hull  Mounting

This  method,  gluing  the  transducer  to  the  hull,  gets  the  same  results  as  if

you  were  using  the  high  speed  transducer,  only  there  are  no  holes  to  drill

in  the  boat  and  there  is  no  transducer  on  the  transom  to  get  damaged  by

impact.

Finding  the  best  location  for  the  transducer  before  you  mount  it  is  critical.

Choose  a  flat  smooth  spot  near  the  center  of  the  bilge  and  near  the  back

of  the  boat.  It  is  a  good  idea  to  make  a  "test  run"  before  you  permanently

install   the   transducer   to   make   sure   that   you   can   indeed   get   a   reading

through  your  hull  and  when  the  boat  is  on  plane.  Put  about  a  half  inch  of

water   in   the   bilge   and   hold   the   transducer   in   the   intended   location.   Move

the  transducer  around  until  you  get  the  best  reading.  Mark  that  spot.
