1. e Observe the outside of the boat hull to find the areas that are mostly free from turbulent water Avoid ribs strakes and other protrusions as these create turbulence Figure 14 e As a general rule the faster the boat can travel the further aft and closer to the centerline of the hull the transducer has to be located to remain in contact with the water at high speeds Step Two Test the Mounting Location There is no opportunity for adjustment after the transducer glued Transducer Mounted Inside the Hull Preferred Mounting Area in place Therefore it is best to perform a trial installation on inside the hull transducers first and run the boat at high speeds to determine the best mounting area 1 At the identified mounting location lay the transducer body face down with the pointed end towards the bow 2 Fill the hull with enough water to submerge the transducer body Use a sand filled bag or other heavy object to hold the transducer in position The transducer cannot transmit through air The water purges any air from between the transducer and the hull and fills any voids in the coarse fiberglass surface 3 INSTALLATION INSIDE THE HULL INSTALLATION Power up the Control Head 4 Run the boat at various speeds and water depths while observing the screen on the Control Head If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds the transducer needs to be moved2. 2 Apply silicone sealant to the mounting holes drilled into the transom Align the transducer assembly with the drilled holes in the transom Figure 8 Use either a flat head screwdriver a 5 16 8mm hex driver or a 5 16 8mm socket to mount the assembly Using the two 10 1 l 25mm long slotted hex head screws mount the transducer f assembly to the transom as shown Do not fully tighten the Lhd mounting screws in order to vertically adjust the transducer Vi Snap the pivot down into place a Step Five Adjust the Running Position of the Transducer The bracket allows height and tilt adjustment the pivot screws allow angular adjustment Initially adjust the transducer as described in the following paragraphs Further adjustment may be necessary to refine the instillation after high speed testing 1 Confirm the pivot angle has not changed Fully tighten the two pivot screws using the Allen wrenches E gt Adjust the height of the assembly so the face of the Running Position First adjust the pivot angle of the transducer body so its Adjustment length is parallel with the length of hull of the boat Then pivot the transducer down so the rear is about 1 4 inch 6mm lower than the front Figure 9 It may be necessary to retighten the pivot screws after the a initial use as the plastics may still be seating to the lock washers transducer is 3 16 4 5mm beneath the lower edge of the transom Figu

If depth performance is required test the fishfinder in water at the desired depth Test different locations in the hull until the optimum performance is achieved Step Three Permanently Mount the Transducer 1 2 Once the mounting location is determined mark the position of the transducer Remove the water from inside the hull and thoroughly dry the mounting surface If the surface is excessively rough it may be necessary to sand the area to provide a smooth mounting surface Ensure the mounting area is clear and dry Mix an ample quantity of two part slow cure epoxy slowly and thoroughly Avoid trapping air bubbles Coat the face of the transducer and the inside of the hull Figure 16 Press the transducer into place with a slight twisting motion to purge any trapped air from underneath keeping the pointed end of the transducer body pointed forward Figure 17 Note Proper operation requires the pointed end of the transducer body to face towards the bow 6 Weight the transducer so it does not move while the epoxy is curing When the epoxy cures no water is necessary inside the hull Neither water spilled gasoline or oil will affect the performance of the transducer INSTALLATION CONTROL HEAD INSTALLATION CONTROL HEAD INSTALLATION Step One Determine Where to Mount Begin the installation by determining where to mount the control head Consider the following to determine best location e The c

11. Thru Hull Mounting Thru hull transducers install through a hole drilled in the hull of the boat Larger boats or boats with inboard motors create turbulence that make transom mounting ineffective Also hulls that are very thick or are double layered or made from materials such as wood or metal which do not conduct sonar signals make inside the hull mounting inadvisable Thru hull mounting may require the use of a fairing block to level the transducer with the waterline Also since special tools and knowledge may be required to perform this type of installation it is best to refer to a qualified marine technician INSTALLATION PREPARATION TRANSDUCER EXCHANGE TRANSDUCER EXCHANGE Other transducers are available as replacements for the standard transducer You may exchange your new and unassembled transducer for another type by returning it to the address listed in Customer Support Some transducers may have additional cost Refer to the Accessory catalog or call Customer Support for information BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder The installation guide included on the next few pages provides detailed step by step instructions for installation of the control head and transducer For transom mount transducer installations you will need the mounting template included with your manual In addition to the parts included y
