1.3 Installation of Transducers
Installing the inside-hull mount transducer
Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
• Silicone grease
Remarks on installation
• Do the installation with the boat hauled out of the water.
• Turn off the engine while installing the equipment.
• Install the transducer in the engine room.
Selecting the mounting location
Keep the following points in mind when selecting a mounting loca-
tion:
• 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 ribes 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.
