3.4 Transducer mounting

The mounting procedure below should be read thoroughly before attempting
to mount the transducer.
Important:
• Only perform the installation with your vessel out of the water.
• Do NOT lift or suspend the transducer using its cable.
• Ensure that the transducer body is supported during installation.
• Do NOT remove the label attached to the transducer cable; as it helps to
ensure correct connection.
• Do NOT overtighten the hull nut or anti-rotation bolt. Overtightening
can cause damage to the hull which may result in water leaking into
the vessel.
