Transom Transducer Mounting; In-Hull Transducer Mounting - VEXILAR FL Series Owner's Manual

T R ANS OM TR AN S DU C E R MO UNT I NG
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.
To Install the High-Speed Transducer
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 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 of 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® contain 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.

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.
To Install the In-Hull Transducer
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
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.
