– choose mounting positions that are symmetric about the center line of the vessel.
– choose mounting positions that are at least 300 mm (12 inches) below the water line.
• Transducers should be installed in a location where there is sufficient clearance inside the hull to
fit the nut and have at least 100 mm (4 in) of headroom to allow for withdrawal.
• To avoid interference with the internal magnetometer, mount transducers at least 1 m (39 inches)
from other electrical devices.
Cored fiberglass hull mounting
It is recommended that the transducer is mounted in a non-cored section, if installation in a cored
section is required then the area around the hole must be adequately strengthened to ensure it is
not damaged when tightening the hull and anti-rotation nuts.
Important: Installation in a cored fiberglass hull should only be carried out by a competent
marine installer.
