The transducer must be in clean (non-turbulent) water for
optimal performance.
• On single-drive boats, the transducer must not be mounted in
the path of the propeller.
The transducer can cause cavitation that can degrade the
performance of the boat and damage the propeller.
• On twin-drive boats, the transducer should be mounted
between the drives, if possible.
• Mount the transducer cable cover well above the water line
.
• Apply marine sealant to all screw threads to prevent water
from seeping into the transom
• This transducer has an integrated spray guard, but if your
transducer throws an excessive amount of water spray,
recheck these mounting considerations and adjust the
position of the transducer as needed to eliminate the spray.

NOTE: The bolt should be tight enough to hold the
transducer in place when the boat moves at high speed, but
loose enough to allow the transducer to pivot out of the way if
the transducer hits an obstruction.
Installing the Transom-Mount Hardware
If you are mounting the bracket on fiberglass with screws, it is
recommended to use a countersink bit to drill a clearance
counterbore through only the top gel-coat layer. This will help to
avoid cracking in the gel-coat layer when the screws are
tightened.
The cables connected to the transducer should not be cut,
because cutting the transducer cables voids your warranty.

Wrap a piece of tape around a 4 mm (

If you are installing the bracket on fiberglass, place a piece of
tape over the pilot-hole location to reduce cracking of the gel
coat.

Apply marine sealant to the included 20 mm screws, and

Route the cable under the transom mount cable hook.
11
If you must route the cable through the transom, choose a
pilot-hole location well above the waterline and mark it.
12
Place a cable clamp on the transducer cable, approximately
halfway between the transducer and the top of the transom or
the pass-through pilot hole.

Mark the pilot-hole location for the cable clamp, and using a

Apply marine sealant to the included 12 mm screw, and

If you marked a pilot hole in step 11, use a 25 mm (1 in.) drill
bit to drill a pass-through hole completely through the
transom.
16
Route the transducer cable to the chartplotter:
• If you are routing the cable using a pass-through hole,
push it through the pass-through hole, and install the
cable-entry cover
(Installing the Cable-Entry Cover,
page
2).
• If you are not routing the cable using a pass-through hole,
route the cable up and over the top of the transom.
You should avoid routing the cable close to electrical wires or
other sources of electrical interference.
Installing the Cable-Entry Cover
If you routed the cable through the transom after you installed
the transducer, you should install the cable-entry cover to keep
water from entering your boat.
