Garmin Ultra High-Definition Scanning Sonar System TransomTrolling Mount Trans - Page 3

5 Apply marine sealant to the included 12 mm M4 screws, and attach the cable-entry cover to the transom. 6 Wipe away all excess marine sealant. Testing the Installation NOTICE You should check your boat for leaks before you leave it in the water for an extended period of time. Because water is necessary to carry the sonar signal, the transducer must be in the water to work properly. You cannot get a depth or distance reading when out of the water. When you place your boat in the water, check for leaks around any screw holes that were added below the water line. Testing the Transom-Mount Transducer Installation NOTICE When adjusting the depth of the transducer, make the adjustments in small increments. Placing the transducer too deep can adversely affect the performance of the boat and put the transducer at risk of striking underwater objects. Test the transom-mount transducer installation in open water free of obstacles. Pay attention to your surroundings as you test the transducer. 1 With the boat in the water, turn on the chartplotter. 2 Drive the boat at a slow speed. If the chartplotter appears to be working properly, gradually increase speed while observing the chartplotter. 3 If the sonar signal is suddenly lost or the bottom return is severely degraded, note the speed at which this occurs. 4 Return the boat to the speed at which the signal was lost, and make moderate turns in both directions while observing the chartplotter. 5 If the signal strength improves while turning, adjust the transducer so that it extends another 1/8 in. (3 mm) below the transom of the boat. 6 Repeat steps 2-4 until the degradation is eliminated. 7 If the signal does not improve, move the transducer to a different location on the transom, and repeat the test. Installing the Transducer on a Trolling Motor Assembling the Trolling Motor Mount 1 Using the 8 mm M4 screws and 4 mm star washers , attach the trolling motor mount to the transducer . 2 Place the transducer mount against the body of the trolling motor with the narrow end of the transducer pointed away from the propeller. 3 Secure the hose clamp around the body of the trolling motor, and tighten the hose clamp. 4 Position the transducer so it is parallel to the bottom when in use. 5 Use cable ties (not included) to secure the transducer cable. 6 Route the transducer cable to the installation location of the sounder while taking these precautions. • The cable should not be routed close to electrical wires or other sources of electrical interference. • The cable must not be pinched when the trolling motor is deployed or stowed.

Installing the Transducer on a Trolling Motor NOTICE Do not cut the transducer cable. Cutting the transducer cable will void your warranty. 1 Insert a hose clamp (not included) through the slot on the transducer mount , until equal lengths extend on both sides of the mount. © 2020 Garmin Ltd. or its subsidiaries Garmin® and the Garmin logo are trademarks of Garmin Ltd. or its subsidiaries, registered in the USA and other countries.
