Garmin GT8HW-TM Plastic Transom or Trolling Motor Mount Transducer High Wide CHI - Page 1

GT8HW-TM Transducer Mounting Consideration To ensure peak performance with the lowest noise and interference, you should route the transducer cable away from ignition wires, house batteries and wires, trolling motor batteries and wires, and high-energy wires such as radar, audio amplifier, and autopilot pump wires. Installation Instructions Assembling the Transducer Attach the transducer to the mount with the included lock À nut , rubber washer , metal washer , and bolt . Á Â Ã Ä NOTE: The bolt should be tight enough to hold the transducer in place when the boat moves at high speed, but loose enough to allow the transducer to pivot out of the way if the transducer hits an obstruction. Important Safety Information WARNING See the Important Safety and Product Information guide in the chartplotter or fishfinder product box for product warnings and other important information. You are responsible for the safe and prudent operation of your vessel. Sonar is a tool that enhances your awareness of the water beneath your boat. It does not relieve you of the responsibility of observing the water around your boat as you navigate. CAUTION Failure to install and maintain this equipment in accordance with these instructions could result in damage or injury. Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding. NOTICE When drilling or cutting, always check what is on the opposite side of the surface. To obtain the best performance and to avoid damage to your boat, you must install the Garmin® transducer according to these instructions. Read all installation instructions before proceeding with the installation. If you experience difficulty during the installation, contact Garmin Product Support. Tools Needed • Drills and drill bits • Number 2 Phillips screwdriver • Masking tape • Marine sealant Preparing the Transducer for Long-Term Exposure to Water NOTICE Do not use acetone or acetone-based products on the transducer. Acetone damages the plastic transducer housing. When you install a transducer on a boat that spends a significant amount of time in the water, you should coat the transducer and mounting hardware with a water-based antifouling paint to prevent marine growth. 1 Lightly sand the transducer and mounting hardware with a fine-grit abrasive pad. 2 Wipe the transducer and mounting hardware with isopropyl alcohol. 3 Apply water-based anti-fouling paint to the transducer and mounting hardware. Installing the Transducer on a Transom Mounting Location Considerations • The transducer should be mounted as close to the center of the boat as possible. • The transducer should not be mounted behind strakes, struts, fittings, water intake or discharge ports, or anything that creates air bubbles or causes the water to become turbulent. The transducer must be in clean (non-turbulent) water for optimal performance. • The transducer should not be mounted in a location where it might be jarred when launching, hauling, or storing. • On single-drive boats, the transducer must not be mounted in the path of the propeller. The transducer can cause cavitation that can degrade the performance of the boat and damage the propeller. • On twin-drive boats, the transducer should be mounted between the drives, if possible. Installing the Transom-Mount Hardware NOTICE If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid any cracking in the gel-coat layer when the screws are tightened. The cables connected to the transducer should not be cut, because cutting the transducer cables voids your warranty. 1 Position the transducer mount so the center of the bottom À of the transducer is level with the bottom edge of the transom and is parallel to the water line.
