HUMMINBIRD 530509-8 Inside the Hull Mounted Transducer

Before you start the installation, we encourage you to read these instructions carefully in order to get the full benefit from your Humminbird® accessory.

NOTE:
1Due to the wide variety of hulls, only general instructions are presented in this guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. For detailed information about installing transducers on different hull types, download the Transducer Installation Resource Guide from our Web site at humminbird.com.

NOTE:
Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount in exactly the same way.

Installation Preparation

• Install the control head before you start the transducer installation. See the control head installation guide.
• Review your boat manufacturer’s owner’s manual for recommended transducer installation locations and cable routing methods.
• Read and understand your boat’s warranty before starting this installation.
• Visit our Web site at humminbird.com for additional information and resources for transducer installations. Also, visit youtube.com/humminbirdtv for informational videos.
• Confirm your boat is level for the installation.
• Supplies for Temp Probe: In addition to the parts supplied, you will need a hand drill with various size bits, marine-grade silicone sealant, and various hand tools.

Installation

There are a number of ways to install a transducer on your boat. Inside the hull mounting of the transducer generally produces good results in single thickness fiberglass hulled boats. Humminbird cannot guarantee depth performance when transmitting and receiving through the hull of the boat, since some signal loss will occur. The amount of loss depends on hull construction and thickness, and the installation.

NOTE:
This type of installation requires the use of a slow-cure two-part epoxy. Do not use silicone or any other soft adhesive material to install the transducer, as this material will reduce the sensitivity of the unit. Do not use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, which reduces signal strength.

1. Locate the Transducer Mounting Position
   Decide where to install the transducer on the inside of the hull, using the following procedures to find the best location:

2. 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.

3. Make sure that the transducer is located as close to the centerline of the hull and as far aft as possible, so that it will remain in contact with the water even at high speeds.

4. Trial Installation
   You will not be able to adjust the mounting position after you install this transducer inside the hull. In order to determine the best mounting area (before permanently mounting the transducer), it is best to perform a trial installation first that includes running the boat at various speeds.

5. Connect the transducer cable connector to the control head.

6. Power on the control head. When the control head detects a functioning transducer, it will start Normal mode automatically. Select a sonar view to display on-screen.

7. 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 mounted inside the hull.

8. Place the transducer body face down at the identified mounting location inside the hull, oriented as shown in the illustrations (see Transducers with Directional Bias and Transducers without Directional Bias).

9. 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.
   NOTE: The transducer cannot transmit through air, so the water is necessary to purge any air from between the transducer and the hull, and to fill any voids in the coarse fiberglass surface of the hull.

10. View the sonar signal on the control head display and compare it against what you observed in step 3, making sure that the boat is in the same location as it was during your observations in step 3. If the results are comparable, continue to step 7. Otherwise, locate a new position in the hull and repeat steps 4 through 6.

11. 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, continue to step 8. If the performance is not acceptable, repeat steps 4 through 7.

12. Once you have determined the best mounting location using this procedure, mark the position of the transducer.

13. Power off the control head. Unplug the transducer cable connector from the control head.

14. Install the Transducer

15. After marking the location of the transducer, remove the water from inside the hull. Thoroughly dry the mounting surface.

16. Mix an ample quantity of two-part slow-cure epoxy. Coat the face of the transducer and the inside of the hull.

17. See the illustrations Transducers with Directional Bias and Transducers without Directional Bias. Identify your transducer shape to determine how it needs to be oriented inside the hull.(You will install the transducer in step 4.) It is important to consider the following:

  * If you have a transducer with directional bias, use the illustration to confirm which end of the transducer points forward to the bow of the boat.
  * If you have an angled-style transducer, position the transducer so it transmits straight  

down and remains in parallel alignment with the keel.

  * If you have a puck transducer (round), it does not need to be set in a certain direction unless it is also an angled-style transducer. See Transducers without Directional Bias.
4. Press the transducer in place with a slight twisting motion to purge any trapped air from underneath.
5. Weight the transducer so that it does not move while the epoxy is curing.
6. When the epoxy has cured, no water will be necessary inside the hull, and water or spilled gasoline or oil will not affect the performance of the transducer.

4. Route the Cable
   Use the following instructions to route the cable to the control head.
   NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.

5. Route and secure the transducer cable to the control head, avoiding areas where it may be damaged or interfere with normal boating operations.
   CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50′. For assistance, contact Humminbird Technical Support.
   CAUTION! Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to prevent corrosion. Dielectric grease can be purchased separately from a general hardware or automotive store.
   Excess Cable: If there is excess cable that needs to be gathered at one location, 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.

6. Connect the Cable
   Refer to your control head installation guide for additional details.

7. Connect the transducer cable to the transducer port on the control head. The connector is keyed to prevent reversed installation, and insertion should be easy. Do not force the connectors into the ports. If the cable connector is round, hand-tighten the screw nut to secure the cable connection. Hand-tighten only!

8. Proceed to Install the Temp Probe (if applicable) or Set up the Transducer on the Control Head.

9. Install the Temperature Probe (If Applicable)
   The Temperature Probe incorporates a temperature-sensitive probe in a high impact plastic housing. The probe is intended for installation on the transom and will work well on almost any boat.
   NOTE: The temperature probe is only available on certain models. Contact Humminbird Technical Support for details.
   Supplies: In addition to the parts supplied, you will need a hand drill with various size bits, marine-grade silicone sealant, and various hand tools.
   Temperature Probe Mounting Location: Locate an area on the transom of your boat 6″ to 8″ or farther from the transducer(s). This area must stay in contact with the water at high speeds. Do not mount the sensor directly in front of the propeller or outdrive, and make sure that there are no protrusions such as ribs, rows of rivets, or transducers directly forward of the mounting location, as these may affect the flow of water over the temperature probe.

10. Either route the cable from the in-hull mounted transducer over the top of the transom or drill a 5/8″ hole in the transom directly above the sensor, above the waterline.
    CAUTION! The temperature probe incorporates a temperature-sensitive probe in a high-impact plastic housing with 10 feet of cable. Do not cut or shorten the temperature probe cable, and try not to damage the cable insulation. The probe is intended for installation on the transom and will work well on almost any boat.

11. Assemble the sensor in the clamp, and align it on the transom so the lower edge of the temperature probe sensor is flush with the hull of the boat, and so that it doesn’t extend below the hull. Mark the hole location.

12. Drill a 1/8″ mounting hole approximately 3/4″ deep.
    NOTE FOR FIBERGLASS HULLS: It is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer fiberglass coating.

13. Seal the mounting hole with marine-grade silicone sealant, and attach the sensor to the transom using the provided screw.

14. If a thru-hole is used, an escutcheon plate is included to dress the hole. Place the escutcheon plate over the cable hole and use it as a guide to mark the two escutcheon plate mounting holes. Remove the plate, drill two 9/64″ diameter x 5/8″ deep holes, then fill all holes with marine-grade silicone sealant. Place the escutcheon plate over the cable hole and attach it with two #8 x 5/8″ wood screws.

15. Route and secure the cable by attaching the supplied cable clamps to the transom. Drill one 9/64″ diameter x 5/8″ deep hole for each cable clamp. Fill the hole with marine-grade silicone sealant, and attach the cable clamp to the transom using a #8 x 5/8″ screw.

16. If the connection is correct, the Humminbird unit will begin displaying water temperature immediately. If the gauge fails to read at high speeds, adjust the height of the sensor on the transom of your boat.

17. After final high-speed adjustments have been made, if a thru-hull hole was used, seal the hole with marine-grade silicone sealant.
    NOTE: The cabling from your transducer should already be routed from its location to the control head. The cabling from the temperature probe goes into the transducer module and its readings are transferred through the same cable to the control head. Refer to your control head installation guide for more information about the quick disconnect or connector collector included with your control head.

18. Set up the Transducer on the Control Head
    Use the following instructions to set the transducer type in the control head. When you select the transducer type, the related views and menus will be added to the system. Before you proceed, review the following information:

    • If your transducer has the round cable connector, the control head will automatically detect the transducer and configure it with the control head. For additional configuration information, see your control head operations manual. The instructions in this section do not apply to your fishing system.
    • If your control head does not include the Connected Transducer menu option, no further action is required. The transducer will be detected automatically if it is compatible with the control head. See your control head operations manual for details.
    1. Press the POWER key to power on the control head.
    2. Press the MENU key. When the control head detects a functioning transducer, it will automatically start Normal operating mode. Follow the on-screen prompts.
    3. Main Menu: Press the Menu key twice.
    4. Use the Cursor Control key to select the Sonar tab > Connected Transducer.
    5. Press the RIGHT or LEFT Cursor keys to select the transducer type. The available menu options are determined by the transducer model you have attached.
    6. Close: Press the EXIT key until the Menu System is closed. Your control head is now ready for operation.
