1.3 Installation of Transducers
Installing the inside-hull mount transducer
Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
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 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 trans-
ducer 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 proce-
dure for this is shown later.
