1.3Transducer

Inside-hull mounting

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

Necessary tools

You will need the following tools:

Sandpaper (#100)

Silicone sealant

Remarks on installation

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

Install the transducer in the engine room.

Do not turn on the echo sounder except if installing the transducer by the inside-hull mounting method. The transducer may become damaged if the power is turned on in other types of installations.

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 that 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.
