Raymarine L470 Assembling the Transducer Bracket, Positioning the Transom-Mount Transducer

Use a trolling motor transducer if –

. . . you want to attach the transducer to a trolling motor. (Not recom- mended for deep water operations.)

Use a Sidelooker transducer –

. . . for searching for fish or structure on either side of the boat. This type of transducer is attached to the bracket of the transom-mount transducer, or to the shaft of the trolling motor.

Assembling the Transducer Bracket

Fit together the two parts of the transducer bracket as shown in Fig. 2-2. When the installation is complete, the parts snap together as shown.

Positioning the Transom-Mount Transducer

Begin by finding the best location for the mounting bracket. Here are the rules:

•If your boat has one propeller (outboard or inboard-outboard), mount the transducer about 18" (455 mm) to the side of the centerline of the boat. See Fig. 2-3. Choose the side that is on the downstroke of the propeller. (This is usually the starboard side of the boat.) This will reduce interference caused by air bubbles.

•If the propeller can be turned to steer the boat, allow at least 2" (50 mm) beyond the swing radius of the propeller. This will prevent the propeller from damaging the transducer when it is turned. After installation, check the clearance by turning the wheel so the propeller swings toward the transducer. There should always be a 2" (50 mm) clearance.
