• Always have the entire bottom face of the transducer under water, when the boat is stopped or at speed. Not interfere with, or be damaged by, launching or retrieving if the boat is trailered. Be convenient for the cable to go through the transom into the boat. Installing Important: Do not cut the transducer cable to shorten it. 1 Select a suitable position for the transducer (see Position of transducer - previous page). 2 Tear the drilling template from inside the back cover of this manual and cut to size. 3 Hold the drilling template in place on the transom. Mark four screw holes through the template so that they will be positioned in the middle of the transducer bracket’s slots: • For fibreglass (GRP) or wooden hulls, ensure the entire bottom face of the transducer will always be approximately 1/4" (6 mm) (dual frequency transducer 1/2" (12 mm)) beneath the surface of the water, including when the boat is at speed. • For aluminium hulls, ensure the entire bottom face of the transducer will always be approximately 1/2" (12 mm) (dual frequency transducer 3/4" (18 mm)) beneath the surface of the water, including when the boat is at speed. Note: Locating the screws at the midpoints in the slots enables the transducer to be moved up or down later. 4 Drill the four screw holes 5/64" (2 mm) diameter and at right angles to the transom, so that when the screws are tightened the screw heads sit flat. Drill 5/64" (2 mm), apply sealant in holes (after adjusting and testing) Screw transducer onto transom 5 Attach the mounting bracket with the four longer stainless screws provided, slide the bracket up or down until the screws are in the middle of the slots, then tighten the screws temporarily. 6 If necessary, loosen the transducer pivot bolt so that the transducer can rotate. Note: the transducer rotates in ‘clicks’ of 7 degrees. Parallel Fit the transducer so that its axis is vertical. 1/4" (6 mm) or 1/2" (12 mm) or 3/4" (18 mm) Push end down 1 click 7 Hold a straight edge on the bottom of the hull and rotate the transducer so that the bottom surface of the transducer is parallel to the bottom of the hull (to the closest click). 8 Push the end of the transducer down by one click. Tighten the pivot bolt until the rubber washer on the pivot bolt starts to compress, then add another 1/4 turn. If the transducer kicks up when at speed, then tighten the pivot bolt more. Note: The face of the transducer should face forward by about 7 degrees when the boat is moving. Pivot bolt 4 NAVMAN Transom Mount Transducers Installation Manual
If the cable is to pass through the transom: 1 2 Cable clamp Drill 3/4" (19 mm) hole in transom Insert cable through hole Drill 7/64" (3 mm), apply sealant in holes Fit screws 3 Cable cover Mark holes, Drill 7/64" (3 mm) Apply sealant Fit screws Drill the hole a safe distance above water line. If you are unsure where to put the hole, consult a qualified boatbuilder. Do not cut the cable. Wiring Cleaning and maintenance Transom Mount Transducers Installation Manual Fit one or two cable clamps on transom to hold cable. Important: Fit a cable clamp close to the transducer. This may prevent the transducer from causing damage should the bracket break while the boat is moving. The transducer has a cable to connect it to the navigation instrument. When fitting this cable: • Keep the cable away from other cables and equipment (for example fluorescent lights, power inverters and VHF transmitters). • Do not cut the cable. • If necessary, extend the cable by adding a NAVMAN 13 ft (4 m) extension cable (a Adjusting and testing Adjust and test the transducer after the transducer and instrument have been installed and with the boat in at least 6 ft (2 m) of water. 1 With the boat moving slowly, turn the instrument on. If the depth does not display, follow the troubleshooting instructions in the instrument manual. 2 Gradually increase boat speed. If the depth does not display then: i Remove any oil from the transducer by wiping the face of the transducer with mild detergent on a cloth. ii Adjust the angle of the transducer by pushing the end down another click. iii Loosen the screws then slide the transducer mounting bracket down or up in steps of 0.1" (2.5 mm) to achieve NAVMAN Fit cable cover over cable hole in transom. Fill the following with sealant: • Cable hole in transom. • Inside the cable cover. • The screw holes. maximum of one cable can be used). Ensure no cable connectors lay in the bilge. Note: There is no extension cable available for the FISH 4100. Secure the cable at regular intervals. Refer to the navigation instrument’s installation manual for instructions on how to connect the cable to the instrument. best high speed performance. Several adjustments might be required to find the optimum position. iv Review the position of the transducer (see Position of transducer at the beginning of this manual). 3 Once adjustments are completed, ensure that all screws are tight, the pivot bolt is tight and all holes are filled with sealant. Note i: If the transducer kicks up at high speed then the pivot bolt needs to be tighter. Note ii: If you find that your transducer is causing a ‘Rooster tail’ then the likely cause is the transducer being mounted too deep. Lifting the transducer mounting on the transom should solve the problem. Clean a transducer with a damp cloth or mild detergent. Avoid abrasive cleaners and petrol or other solvents. When repainting the hull, cover or remove any transducers. Do not paint the transducer. Do not use a high pressure water blast on a speed sensor paddlewheel as it may damage the bearings. 5
