FISH450 Tricolor FISHFINDER
Installation and Operation Manual
NAVMAN
The location and angle of the Aquaducer are the
most critical parts of the installation. If the location
and angle are not correct, the Aquaducer can’t
perform at its designed potential.
Transom mount Aquaducer
IMPORTANT - the Aquaducer cable cannot be cut
or shortened.
The Aquaducer can be installed on any outboard or
stern-drive powered boat. Inboard powered boats must
be fitted with a through-hull transducer as the propeller
wash interferes with the operation of transom mounted
transducers. The transom mount Aquaducer has a
safety “kick up” mounting bracket which will normally
prevent damage to the Aquaducer should it impact
the bottom or floating debris in the water.
Final position of Aquaducer:
Location
Select a position for the Aquaducer that will:
•
allow the Aquaducer a smooth flow of water
over its surface at all times.
•
ensure a mount as deep in the water as
possible.
•
be clear of any interference from the trailer
when launching or retrieving the boat.
•
be away from planing strakes or other
projections from the hull that may cause
aerated water to flow over the face of the
transducer.
•
be away from the propeller.
•
be at least 150 mm (6") away from the keel
of the boat.
Mounting
•
IMPORTANT -
place the Aquaducer against
the transom and check that the bottom
surface is angled approximately 5° forward
in order to minimise the generation of
bubbles through cavitation. If necessary, use
one or more of the three wedges provided
(one 4° and two 8°) to achieve this angle.
•
Position the bracket and selected wedge(s)
as low as possible without any part
protruding below the hull. Mark the screw
hole centres on the transom through the
centre of the bracket slots. Mark them so that
when the screws are tightened the screw
heads sit flat on the surface of the bracket.
•
Drill the two screw holes using a 3 mm drill
bit. Make sure the holes are angled so that
when the screws are tightened the screw
heads sit flat on the surface of the bracket.
•
Insert the Aquaducer into the
bracket. Use the stainless screws
provided to attach the bracket and
wedge(s) to the transom. Ensure
again that the top of the bracket
is horizontal and that the
bracket is as low as
possible without
protruding below the
hull. Fill holes with a
sealing compound before
inserting screws. Tighten the two screws.
•
Drill a hole and insert the third screw in the
middle of the bracket.
•
Finally push the Aquaducer down so it
‘clicks’ into place.
•
Once in place test the Aquaducer is
connected by turning the unit on. If the
Aquaducer is not connected then the
message “No transducer detected. Enter
simulation mode? Yes/No” will appear. (see
Simulate Mode
section 4-10). Please see the
