  • Page 9: Understanding The Fishfinder Screen

    Understanding the Fishfinder Screen Experimentation and experience are the keys to successfully interpreting your Fishfinder screen. We recommend that you take your Fishfinder out on familiar water, and spend time learning to interpret what you see on the Fishfinder 90 or 140 screen.

  • Page 10: Using Simulator Mode

    Getting Started The Fishfinder 90 and 140 include the latest technology in interpreting bottom signals; they can see through fish, structures, and thermoclines (shown in the weakest hues). Even so, large schools of fish or dense structures close to the bottom can affect water depth return readings. NOTE: If the Fishfinder is unable to track the bottom for any reason, the digits which indicate depth flash on and off to alert you that the Fishfinder is not tracking the bottom.

  • Page 11: Installing Your Fishfinder

    Make sure you completely read and understand all instructions before you install and use your Fishfinder. If you have problems, contact Garmin Product Support, or seek other professional assistance. You can install the Fishfinder hardware on a transom or on a trolling motor.

  • Page 12: Installing The Transducer

    Installing Your Fishfinder Installing the Transducer Assembling the Transducer 1. Insert the rubber washer (Q) and plastic spacer (P) into the transducer (G) at the same time. DO NOT lubricate the rubber washer. 2. Route the cable toward the back of the transducer. Slide the transducer into the transducer mount (H).

  • Page 13: Mounting The Transducer On A Transom

    4. Wrap the two ends of the cable tie around the motor body. Place the pointed end of the cable tie through the fastener hole on the opposite end and pull it through until it is snug but not tight. (The cable tie clicks when you pull it.) 5.
  • Page 14 Installing Your Fishfinder • DO NOT mount the transducer in the path of the prop on single-drive boats. The transducer can cause cavitation that can degrade the boat’s performance and damage the prop. On twin-drive boats, mount the transducer between the drives, if possible.
  • Page 15 To mount the transducer on a transom: 1. Position the transducer mount at the selected transom location. Make sure the transducer is parallel with the water line. Mark the center locations of each hole on the transducer mount. (See the figures on the next page.) 2.

  • Page 16: Installing The Fishfinder Unit

    Installing Your Fishfinder Drill pilot holes here. Level Align with the transom bottom. The transducer should extend 1/8" below fiberglass hulls or 3/8" below aluminum hulls. Keep it parallel with the water line. 190-00582-10_0A.indd 10 Installing the Fishfinder Unit Selecting a Fishfinder installation Location Select a Fishfinder installation location that allows you to view and operate it easily while operating the vessel.
  • Page 17 To mount the bracket assembly: 1. Using the tilt mount bracket (Fishfinder 90) or the swivel base (Fishfinder 140; Fishfinder 90 option) as a template, mark the location of the three holes that you use to secure the bracket to the mounting surface. 2.

  • Page 18: Installing The Wiring Harness

    Installing Your Fishfinder Installing the Wiring Harness The Fishfinder comes with a wiring harness that connects the Fishfinder to power and the transducer with one easy-to-remove connection. If it is necessary to extend the power wires, use 22 AWG wire. DO NOT cut the transducer cable, because this voids your warranty.

  • Page 19: Testing The Transom Mount Installation

    Testing the Transom Mount Installation Perform this test after you install the Fishfinder. Because you need water to carry the sonar signal, the Fishfinder does not function properly with the transducer out of the water. When you place your boat in the water, CHECK FOR LEAKS around the screw holes that are below the water line.

  • Page 23 Graphs Fish ID—sets how the Fishfinder shows underwater targets and background information. If you select a fish symbol, the screen shows only the information related to that symbol (large, medium, and small sizes). When using wide beam, fish symbols that are to the sides of the boat appear hollow.
  • Page 24 Operating Your Fishfinder Auto Gain—controls the aggressiveness of the Auto Gain. The higher the setting, the greater the number of targets appear on the screen. The lower the setting, the less clutter on the screen. The settings are High, Medium (default), and Low.
