    optional trolling motor mount uses a one-piece plastic bracket with an adjustable strap. These are "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools.

    or similar tool for stirring and applying epoxy, and a paper plate or piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100 grit sandpaper, specially formulated epoxy adhesive available from LEI (see ordering information on the inside portion of the back cover). A sandwich hull also requires polyester resin.

    closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen.

  • Page 17: Shoot-Thru-Hull Vs. Transom Mounting

    Transom Hull bottom Align transducer centerline with hull bottom. A dual frequency trans- ducer is shown at left and a single frequency transducer at right. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be coming out of the water as you cross waves or wakes.

  • Page 18: Transom Transducer Assembly And Mounting

    Typically, shoot-thru-hull installations give excellent high speed opera- tion and good to excellent depth capability. There is no possibility of transducer damage from floating objects, as there is with a transom- mounted transducer. A transducer mounted inside the hull can't be knocked off when docking or loading on a trailer.

Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratch- ets. Temporarily slide the bolt though the transducer assembly and hold it against the transom.
  • Page 21 holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's par- allel with the ground.
  • Page 22 parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat step 2B, but use a different alignment letter until you can place the transducer on the transom correctly. Flat washer Assemble transducer and bracket. 3.
  • Page 23 Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The trans- ducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of each slot for the mounting screw pilot holes.
  • Page 24 Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the caulking compound. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn.

  • Page 25: Trolling Motor Bracket Installation (Single-Frequency Only)

    If you need to drill a hole in the transom to pass the connector through, the required hole size will be 5/8". Caution: If you drill a hole in the transom for the cable, make sure it is lo- cated above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline seal- ant used for the mounting screws.

Transducer mounted on trolling motor, side view. Transducer Orientation and Fish Arches If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds.
  • Page 27 Transducer aimed too far back Full fish arch Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the trans- ducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised.

  • Page 28: Shoot-Thru-Hull Preparation

    Shoot-Thru-Hull Preparation Hulls With Flotation Materials The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass lay- ers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area.

  • Page 29: Testing Determines Best Location

    pass through solid fiberglass. Any air bubbles in the fiberglass or the ep- oxy will reduce or eliminate the sonar signals. Testing Determines Best Location Ideally, the shoot-thru transducer should be installed as close to the transom as possible, close to the centerline. This will give you the best performance during high speed maneuvers.

  • Page 30: Shoot-Thru-Hull Installation

    The second bottom signal will probably disappear and the bottom signal intensity will likely decrease. 3. Now move the transducer around to find the best location with the strongest possible bottom signal. If you find a spot with an acceptable bottom signal, mark the location and move on to step 4.

    Transom Speed sensor mounting configuration: side view (left) and rear view (right.) Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8".
  • Page 36 This may result in corrosion of the plug body along with the electri- cal contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and in- stalling an inline switch.

  • Page 37: Mounting The Unit: Bracket, In-Dash Or Portable

    An optional 8-foot, CA-4 external power cable with a cigarette lighter adapter is available from Eagle. Mounting the Unit: Bracket, In-Dash or Portable You can install the sonar unit on the top of a dash with the supplied gimbal bracket.
  • Page 38 Front Install the gimbal bracket. Orient the bracket so the arms slope toward the front of your unit. Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer cables. The best location for this hole is immediately under the gimbal bracket location.
  • Page 39 137.9 [5.43] Front view (left) and side view (right) showing dimensions of the sonar unit when mounted on gimbal bracket. Before positioning the bracket, be sure to hold the cables against the rear edge of the hole. Then, slide the bracket over the hole and butt the rear of the bracket base firmly against the cables, thus pinning them in place against the side of the hole.

  • Page 100 Weak bottom echo, digital readings erratic, or no fish signals: 1. Make sure the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiber- glass and that it is securely bonded to the hull.
  • Page 101 2. Electrical noise from the boat's motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker sig- nals such as fish or even structure from the display. Try using resistor spark plugs or routing the sonar unit's power and transducer cables away from other electrical wiring on the boat.
  • Page 102 tivity should be set at 90-95 percent. There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonar's display. For example, turn on the bilge pump and view the sonar display for noise. If no noise is present, turn the pump off, then turn on the VHF radio and transmit.
