Route and secure the cable by attaching the cable clamp to the transom; drill one 9/64" diameter x 5/8" deep hole, then fill hole with marine-grade silicone sealant, then attach the cable clamp using a #8 x 5/8" screw. Storing Excess Cable NOTE: If there is excess cable that needs to be gathered at one location (as shown in the illustration), dress the cable routed from both directions so that a single loop is left extending from the storage location. Doubling the cable up from this point, form the cable into a coil. Storing excess cable using this method can reduce electronic interference (see the illustration Storing Excess Cable). 5. Connecting the Cable If you unplugged the transducer cable at the beginning of this procedure, plug it back into the depth sounder. NOTE: The connector is keyed to prevent reverse installation, so be careful not to force the plug into the connector the wrong way. 6. Test and Finish the Installation Once you have installed both the HDR 650 and the transom transducer, and have routed all the cables, you must perform a final test before locking the transducer in place. Testing should be performed with the boat in the water although you can initially confirm basic operation with the boat out of the water. Turn on the power source to power up the HDR. If the unit does not power up, make sure that the connector holder is fully seated in the receptacle and that power is available. If all connections are correct and power is available, the Humminbird® control head will enter Normal operation. If the digital depth readout displays on the screen, the unit is working properly. Make sure that the boat is in water greater than 2' but less than the depth capability of the unit, and that the transducer is fully submerged, since the sonar signal cannot pass through air. Transom Mount Transducer Installation 20 NOTE: The transducer must be submerged in water for reliable transducer detection. 4. If the unit is working properly, gradually increase the boat speed to test high-speed performance. If the unit functions well at low speeds, but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment. If you have the correct angle set on the transducer, yet lose a bottom reading at high speed, adjust the height and the running angle in small increments to give you the ideal transducer position for your boat. First, adjust the height in small increments (see the illustration Adjusting the Transducer Mounting Position). Adjusting the Transducer Mounting Position Leveling the Mounting Assembly Horizontally Level Level Seam aligned with boat hull NOTE: The deeper the transducer is in the water, the more likely that a rooster tail of spray will be generated at high speeds, so make sure that the transducer is as high as it can be and still be submerged in the water. If you are still not getting good high speed readings, you may need to disassemble the transducer mounting assembly and re-position the ratchets (see the illustrations Transducer Knuckle Positions, Ratchets Placed in Position 1, Ratchets Placed in Position 2, and Fitting the Mounting Bracket Over the Ratchet). 21 Transom Mount Transducer Installation Transducer Knuckle Positions Knuckle Ratchets Placed in Position 1 Beads Ratchet Rib at position 1 Ratchets Placed in Position 2 Bead Fitting the Mounting Bracket over the Ratchet Rib Ratchet If you do change the transducer position, re-trace the position of the mounting bracket before proceeding. NOTE: It is often necessary to make several incremental transducer adjustments before optimum high speed performance is achieved. Due to the wide variety of boat hulls, however, it is not always possible to obtain high speed depth readings. 6. Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings. Force the pivot to the Up position to gain access to the mounting screws, then re-align the mounting bracket against the transom of the boat to match the traced silhouette. Check the bracket position with the level again to make sure it is still level, then mark the third mounting hole using a pencil or marker. Unscrew and remove the mounting screws and the transducer assembly and set aside. Transom Mount Transducer Installation 22 7. Drill the third mounting hole, using a 5/32" drill bit.
