Raymarine REALVISION 3D Installation Instructions Manual page 18

1. Outboard or I/O (Planing hull) — mount forward and to the side of the propeller(s).
2. Inboard (Planing hull) — mount forward of the propeller(s) and shaft(s).
3. Stepped hull (Planing hull) — mount on the first step as far aft as possible.
4. Displacement hull — mount approximately 1/3 of the way along the length of the hull,
measured along the waterline.
5. Fin keel (Keel sailboat) — mount forward of the keel, ensuring that the keel will not obstruct
the transducers wide beam width.
6. Full keel (Keel sailboat) — mount away from the keel at a location with minimum dead rise,
ensuring that the keel will not obstruct the transducers wide beam width.
• The mounting surface should be flat so that transducer sits flush against the hull.
• When installing split-pair transducers with angled elements, you must ensure that the hull's
deadrise angle at the chosen mounting location is appropriate for the selected transducers.
• When fitting to a hull with a keel, ensure that the transducer beam will not be obstructed by the
keel. If the transducer cannot be fitted fore or aft of the keel then use split pair transducers to
overcome the obstruction.
• 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.
