4.  INSTALLATION

4. Tape the location shown in the figure be-

low. Fill the gap between the wedge front 
of the transducer and transom with epoxy 
material to eliminate any air spaces.

5. After the epoxy hardens, remove the 

tape.

The thru-hull mount transducer may also be 
installed inside the hull on FRP boats. Howev-
er, this installation method affects the ability to 
detect the bottom, fish and other objects be-
cause the ultrasound pulse is weakened 
when it passes through the hull.

Note: This mounting method should not be 
used to mount the transducer that supports 
the bottom discrimination display feature, 
since performance is greatly degraded.

You will need the following tools:

If the thickness of the hull varies, then the at-
tenuation of the ultrasound pulse. Select a lo-
cation where attenuation is the lowest.

1. Select 2-3 locations considering the four 

points mentioned below. (You will finalize 
the mounting location through some trial 
and error later.)
•  Mount the transducer at a location 1/2 

to 1/3 of the length of the boat from the 
stern.

•  The mounting location is between 15 to 

50 cm from the centerline of the hull.

•  Do not place the transducer over hull 

struts or ribs which run under the hull.

•  Avoid a location where the rising angle 

of the hull exceeds 15°, to minimize the 
effect of the boat's rolling.

2. Clean the face of the transducer to re-

move any foreign material. Lightly rough-
en the face with #100 sandpaper. Also, 

•

• Silicone sealant

•  Do the installation with the ship moored at a 

dock, etc. The water depth should be 6.5-32 
feet (2-10 meters).

•  Turn off the engine.
• 

Install the transducer with the engine 
room.

•  Do not power the unit with the transducer in 

the air, to prevent damage to the transduc-
er.

•  Do not use this method on a double layer 

hull.

•  Before attaching the transducer to the hull, 

check that the site is suitable. Put the trans-
ducer in a water-filled plastic bag. Connect 
the transducer to the display unit and put 
the transducer on the installation site. Turn 
on the display unit and check that the depth 
indication appears.
