    3. Determine the location of your battery or other power connection, along with the power cable route. 4. Install the transducer and route the transducer cable to the sonar unit. 5. Route the power cable from the unit's location to an appropriate power source and connect it there.

  • Page 10: Recommended Tools And Supplies

    Recommended Tools and supplies If you prefer the option of routing the cable through the transom, you will need a 5/8" drill bit. Each transom mount requires use of a high quality, marine grade above- or below-waterline caulking compound. NOTE: The following installation types also call for these recommended tools and required supplies (supplies are not included): Single-frequency transom installations...

    at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine. 3. The transducer should be installed with its face pointing straight down, if possible. For shoot-thru applications: Many popular fishing boat hulls have a flat keel pad that offers a good mounting surface.

  • Page 12: How Low Should You Go

    CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location Poor location Good location Good location Poor angle Good and poor transducer locations. How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull.

    If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the 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.

    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.

    If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8". (If you intend to route an additional speed or temp sensor cable through the same hole, you will need a 1" (25.4 mm) drill bit instead.) Caution: If you drill a hole in the transom for the cable, make sure it is...

  • Page 22: 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 23: Testing Determines Best Location

    sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. Transducer location (high speed) Transducer location (trolling speed) Shoot-thru-hull transducer locations for high speed or trolling speed operation. Testing Determines Best Location Ideally, the shoot-thru transducer should be installed as close to the transom as possible, close to the centerline.

  • Page 25: Shoot-thru-hull Installation

    Shoot-Thru-Hull Installation 1. Make sure the area is clean, dry and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The sanded hull area should be about 1-1/2 times the diameter of the transducer.

    Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain 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 in- side the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull.

    Try using resistor spark plugs or routing the sonar unit's power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish I.D. feature is off: 1. Make certain the transducer is pointing straight down. This is the most common problem if a partial arch is displayed.
