Finalizing The Transducer Mounting - Raymarine Dragonfly-4 Installation And Operation Instructions Manual

Note:
• It may not always be possible to obtain depth
readings at higher speeds due to air bubbles
passing under the transducer.
• It may be necessary to make several
adjustments to the transducer before obtaining
optimum performance.
• If the transducer requires repositioning ensure
all old holes are filled with marine grade sealant.

4.6 Finalizing the transducer mounting

Once you have achieved optimum performance at
the desired vessel speeds the transducer must be
locked into position to complete the installation.
1. Drill the locking hole location taking care not to
damage the mounting bracket.
2. Fill the locking hole with marine grade sealant.
3. Secure the transducer and bracket by fully
tightening all 3 mounting screws.
4. Secure the ratchet arm bolt, by tightening until
the compression washer is compressed and then
add another 1/4 turn. If the transducer kicks up at
speed then tighten further.
Note: Overtightening may cause damage.
