1.5 Inside Hull Mount
This mounting method is available for FRP boats.
1.5.1 Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
• Silicone grease
1.5.2 Remarks on installation
• Turn off the engine and anchor the boat while installing the equipment.
• Install the transducer in the engine room.
1.5.3 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 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.
