4. INSTALLATION

The transom mount transducer is very com-
monly employed, usually on relatively small I/
O or outboard boats. Do not use this method 
on an inboard motor boat because turbulence 
is created by the propeller ahead of the trans-
ducer.
DO NOT overtighten screws. They may be 
damaged.

Choose the installation method depending on 
the rise angle of the hull.

A suitable mounting location is at least 50 cm 
away from the engine and where the water 
flow is smooth.

1. Drill four pilot holes for self-tapping screw 

(5x20) in the mounting location.

2. Attach the transducer to the mounting loca-

tion with self-tapping screws.

3. Adjust the transducer position so the trans-

ducer faces right to the bottom.
If necessary, to improve water flow and 
minimize air bubbles staying on the trans-
ducer face, incline the transducer about 5

°

 

at the rear. This may require a certain 
amount of experimentation for fine tuning 
at high cruising speeds. 

4. Fill the gap between the wedge front of the 

transducer and transom with epoxy mate-
rial to eliminate any air spaces.

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
