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.
•
If your boat has twin propellers (outboard or inboard-outboard), place
the transducer near the centerline of the boat.
•
Do not mount the transducer behind any hull fittings, intakes, or other
parts which extend from the hull. These may cause turbulence or air
bubbles.
•
The bracket has a quick-release mechanism. This may reduce
damage by allowing the transducer to flip up if it hits any debris or the
bottom. See Fig. 2-4. Allow enough clearance above the transducer
so that it can swing upward completely. This is about 10" (254 mm)
measured from the bottom of the transom.
•
If considering the Sidelooker option, look for a mounting location
where the Sidelooker array will not be blocked by the engine housing
or other mounted hardware.
•
If the boat will be carried on a trailer, be sure the transducer will not
hit any rollers, bunks or fittings on the trailer.
Mounting the Transom-Mount Transducer
1.
On a boat with a fiberglass hull, the leading edge of the transducer
should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge of
the hull. See Fig. 2-5. On an aluminum hull, the transducer should
extend a bit more – 1/4" (6 mm) to 3/8" (9 mm). If the boat will be
operated at high speeds, the transducer may be mounted closer to
the centerline of the hull.
2.
The lower surface of the transducer should tilt down toward the rear
at a slight angle (2° to 5°). The mounting bracket includes a wedge.
Depending on the angle of the transom on your boat, you may need
this wedge to get the correct angle for the bottom of the transducer.
3.
Looking
at
the
rear
of
the
boat,
be
sure
the
bracket
is
vertical (perpen-
dicular to the water line).
4.
Hold the bracket (and the wedge, if used) against the transom and
trace the positions of the screw slots.
