[. . . ] Do not use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, thus reducing signal strength. 20 Inside the Hull Transducer Installation Determine the Transducer Mounting Location Decide where to install the transducer on the inside of the hull. Consider the following to find the best location: · 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 28). · 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 in order to remain in contact with the water at high speeds (Figure 29). Figure 28 Preferred Mounting Area Figure 29 21 Inside the Hull Transducer Installation Trial Installation You will not be able to adjust the mounting after an inside the hull transducer is installed. It is best, therefore, to perform a trial installation first that includes running the boat at various speeds, in order to determine the best mounting area before permanently mounting the transducer. Plug the transducer into the control head, then power up the control head. When the control head detects a functioning transducer, it will automatically enter Normal operating mode. View the sonar signal at its best by holding the transducer over the side, immersed in the water, so that it is pointing straight down over a known flat bottom. Use the display to benchmark against the sonar signal that will be detected once the transducer is placed in the hull. Place the transducer body face down at the identified mounting location inside the hull, with the pointed end towards the bow (Figure 28). 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, and the water purges any air from between the transducer and the hull, and fills any voids in the coarse fiberglass surface. View the sonar signal on the display and compare against what was observed in Step 2, making sure that the boat is in the same location as it was during your observations in Step 2. If the results are comparable, move on to Step 6. Otherwise, locate a new position in the hull and repeat Steps 3 through 5. Run the boat at various speeds and water depths while observing the screen on the control head. If depth performance is required, test the transducer in water at the desired depth. If the performance is acceptable, move on to Step 7. If the performance is not acceptable, repeat Steps 3 through 6. Once you have determined the best mounting location using the above steps, mark the position of the transducer. 22 Inside the Hull Transducer Installation Route the Cable 1. Once the mounting location is determined and you have marked the position of the transducer, route the cable from the transducer to the control head. Permanently Mount the Transducer 1.
