Hull

Epoxy material

The thru-hull mount transducer 
(520-5PSD, 520-5MSD) may also be 
installed inside the hull, following the 
procedure below. 
 

You will need the following tools: 

• 

Sandpaper (#100) 

• 

Silicone sealant 

• 

Silicone grease 

 

• 

Turn off the engine and anchor the 
boat while installing the equipment. 

• 

Install the transducer in the engine 
room. 

 

• 

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.

1.  Clean the transducer face to remove 

any foreign material. Lightly roughen 
the transducer face with #100 
sandpaper. Also, roughen the inside 
of the hull where the transducer is to 
be mounted. 

2.  Clean the transducer face again.   
3.  Warm the silicone sealant to 40°C 

before usage to soften it. Coat the 
transducer face and mounting 
location with silicone sealant.
