Transom Mounting - VEXILAR FL Series Owner's Manual

Transom Transducer Mounting
Before you begin the process of installing the transducer, check your hull to find a spot
where you'll get a smooth water flow along the bottom of the boat. You want to avoid ribs,
rivets, and gouges or scratches in the hull.
To get a true vertical depth reading, the
transducer should be mounted parallel to the
water line. However, a 10° tilt to either side is
acceptable. If the hull is reasonably flat with a
dead rise of 10° or less, mount the transducer
along the hull bottom. If dead rise is greater
than 10°, mount the transducer with level
alignment.

1. Assemble the stainless steel brackets to the transducer
using the hardware furnished. Do not tighten until final
adjustments are made.
2. Place assembly on transom at selected location with the
front of the transducer extending 1/2" to 5/8" below
the bottom of the boat and with the front part against the
transom. The least amount that the transducer extends
below the bottom is desired. If too low, spray and turbulence will occur resulting
in lost bottom readings.
3. With transducer in place, mark the four slot locations of the transducer mounting
brackets. Drill in center of slot outline using a 9/64" (3.5 mm) drill.
4. Fasten the transducer to the transom using the
#10 x 3⁄4" screws, nuts and washer plates.
5. Before final tightening the 4 screws holding the
brackets to the transducer, tip the rear edge
down approximately 1/8" as shown.
6. Tighten all screws.
CAUTION: Do not use any thread locking compound
on the screws. Most products such as Loctite
chemicals that attack and weaken plastics.
IMPORTANT:
There should be no gap between the brackets and the transducer. A wide
space between these parts will cause stress on the transducer mounting ears and result in
breakage with time.
When running the cable to the sounder, avoid other wiring on the boat, particularly
ignition and alternator cables. They can be a source of noise on the sounder display.

In-Hull Transducer Mounting
Surface preparation and location are the keys to having a good sonar transducer
installation that will last for years, so please take a few extra minutes to test the
location and prepare the surface area. Also, the hull temperature should be at least 60°
F while performing the installation.
Select an area in your boat. Ideally, for high speed operation, you will need to place the
transducer near the center of the transom area of the boat, which is often near the drain
plug. You must attach the transducer to a solid hull area; this means you cannot have
double hull aluminum or a foam layer in the fiberglass between the transducer and the
water.

1. Prepare the surface area. It is critical you find
a smooth, flat spot to place your transducer.
Small ridges, bumps or even paint under the
transducer will affect the quality of the sonar
signal. Your surface preparation kit comes with
a Scotch-Bright pad to smooth any rough
®
areas down to the base material for a secure
installation. Use the pad to rough-up the face
of your transducer a little too. This will also aid in the long-term quality of your
installation.
2. Clean the area. Use the supplied cleaning patch of Isopropyl Alcohol to remove
dust and dirt from the target mounting area. Be sure to also wipe clean the face of
your transducer. Let dry for a few minutes.
3. Position the transducer. Place the transducer exactly where you want to install it.
Apply the four supplied positioning pads around the transducer. The positioning
pads are needed to prevent your transducer from drifting off the target area while
the A.C.E. adhesive sets up.
4. Mix and apply the epoxy. Follow the mixing directions on the packet of A.C.E.
Adhesive and apply the entire packet contents directly to the face of the transducer.
5. Install the transducer. Place the transducer into position. Press firmly and twist slightly
back-and-forth to work-out any air bubbles that might have been trapped in the
epoxy.
6. Installation complete. Allow the A.C.E. to dry.
CAUTION: Do not power-up your depth sounder for at least 12 hours. Doing so will
effect epoxy curing.
