[. . . ] 988-0176-06_A HDS unit installation instructions Read the following instructions carefully before attempting any installation. Transducer installation recommended tools and supplies (not included) If you plan to route the transducer cable through the transom, you will need either a 1" drill bit or a 5/8" drill bit depending on the size of the transducer cable connector. Each transom mount requires a high quality, marine grade above- or belowwaterline sealant/adhesive compound. The following installations also call for these recommended tools and supplies. One-piece bracket transom installation: Tools: two adjustable wrenches or socket wrench, drill, #29 (0. 136") drill bit, screwdriver. [. . . ] 8 TMB-S trolling motor bracket installation The TMB-S bracket is designed for one-piece bracket transducers only. The TMB-S trolling motor bracket (Part No. 51-45) is an optional accessory and is available through LEI Extras at www. lei-extras. com. The TMB-S bracket is used to attach a one-piece bracket transducer to a trolling motor. If you regularly fish in water with a lot of underwater structure, such as rocks, stumps and trees, you may consider using a Pod transducer for trolling motor installation. Pod transducers cannot be "kicked up" by underwater structure. Internal tooth washer Plastic bracket Bolt Lock nut Flat washer Using the components supplied with the TMB-S bracket (adjustable strap, internal tooth washer and plastic bracket) attach it to the transducer as shown in the diagram above. Adjustable strap Route the transducer cable along the trolling motor shaft. Use plastic ties (not included) to secure the cable to the shaft. Slide the adjustable strap through the plastic bracket as shown above, left, then slip the strap around the trolling motor as shown in the image, at right. Position the transducer so its "face" is pointing straight down when the trolling motor is in the water. Make sure there is enough slack in the transducer cable for the trolling motor to turn freely. 9 Skimmer Transducer shoot-thru-hull installation Before attempting any installation on boats with flotation material sandwiched within the hull, consult the boat manufacturer. In a shoot-thru-hull installation the transducer is epoxied to the inside of the boat hull. Careless grinding or cutting on the hull could damage the integrity of the hull. Contact the boat dealer or manufacturer to confirm hull specifications. Transducer Transducer epoxied to hull. Epoxy Hull The previous image shows a Skimmer transducer epoxied to a flat, solid portion of the boat hull near the transom. The circled image is a close-up view of the transducer epoxied to the hull. On vee hulls try to place the transducer where the dead rise is 10° or less. NOTE: While you can epoxy a Skimmer transducer to the inside of a boat hull, we recommend using a Pod transducer for this type of installation. Once epoxied into position, the transducer can be very difficult to remove. 10 A transducer can not shoot through wood or metal hulls. Wood and metal hulls require either a transom mount or "thru-hull" installation. For shoot-thru-hull applications many boat hulls have a flat keel pad that offers a good transducer mounting surface. If you are using a Skimmer transducer versus a Pod transducer for this installation, make sure the Skimmer transducer is oriented so the nose of the transducer is facing the bow (front) of the boat. Also, if the transducer has a built in temp sensor, it will only show the temperature of the hull, not the water temp. Before you epoxy the transducer to the hull, make sure the area is clean, dry and free of oil or grease. The surface of the hull must be flat so the entire transducer face is in contact with the hull. Sand face where the transducer is to be epoxied, and of transducer the face of the transducer. For shoot-thru-hull applications many boat hulls have a flat keel pad that offers a good transducer mounting surface. Transducer Epoxy Transducer epoxied to hull.

Pass all the cable connectors through the 1-inch hole in the center of the gimbal bracket. Leave enough slack in the cables to allow for tilting of the unit. 17 Gimbal bracket knob Gimbal bracket knob 4. [. . . ]
