• The transducers should be installed away from any protrusions such as
other transducers, steps, ribs, strakes, or rows of rivets.
• Transducers should be installed in a location where no load will be applied
to the transducers during, launching, lifting, trailering and storage of the
boat.
• Transducers must be installed in the correct orientation, with the
anti-rotation bolt closest to the stern of the vessel. Additionally, a direction
arrow pointing to the bow is embossed on the anti-rotation bolt cap.
• When installing split-pair transducers:
– the correct transducer (port or starboard) must be installed in the
matching (port or starboard) side of the hull. The transducers have labels
on the top face that identify which side they should be installed on and
the transducer’s element angle:
1. Direction to vessel bow
2. Element angle and vessel side:
♦ Single (all-in-one) transducers are marked “0°”
♦ Split pair (“12°” or “20°”)
♦ Split pair — port, “P” or starboard, “S”)
3. Split pair — Vessel side and direction to vessel keel (Single all-in-one
transducers do not include this label.)
– each transducer in a split pair have labels on the transducer cables and
also labels on the accompanying ‘Y’ cable which identify the side:
1. Green — Starboard-side Y cable.
2. Green — Starboard side transducer cable.
3. Red — Port side Y cable.
4. Red — Port side transducer cable.
– 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.
