4.4Inside-hull 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.

2.Warm the silicone sealant to 40°C before usage to soften it. Coat the transducer face and mounting location with silicone sealant.
