Transducer
The thru-hull mount transducer (520-5PSD,
520-5MSD) may also be installed inside the
hull, following the procedure below.
Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
• Silicone grease
Remarks on installation
• Turn off the engine and anchor the boat
while installing the equipment.
• Install the transducer in the engine room.
Choosing the mounting location
• Keep the following points in mind when
choosing a mounting location:
• The mounting location should be where
the hull is of single-hull thickness and is
void of air or flotation materials other than
solid fiberglass between the transducer
face and the water.
• 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.
• You will finalize the mounting location
through some trial and error. The
procedure for this is shown later.

Also, roughen the inside of the hull
where the transducer is to be mounted.
2. Warm the silicone sealant to 40°C
before usage to soften it. Coat the
