5. 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.
6. 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.
7. 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.
8. 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.
6.
Setting 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 fishfinder is a PiranhaMAX,
or does not include the Transducer Select or 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/LIGHT 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 4-WAY Cursor Control key to select the Sonar tab > Transducer Select or Connected
Transducer.
5. Press the RIGHT or LEFT Cursor keys to select the transducer type (Dual Beam, Quad Beam, etc.). 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.
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 Customer Service.
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.
3. Insert the transducer cable connector into the appropriate port on the control head, cable collector, or
black box sonar. See your control head installation guide for details.
• The cable connectors are labeled, and there are corresponding labels on the cable collector
and control head. The connectors are keyed to prevent reversed installation, and insertion
should be easy— do not force the connectors into the ports.
•
If the connector on the cable is round,
it has a screw nut (see the illustration
Transducer
Connectors
). Hand tighten the screw nut to secure the cable connection. Hand tighten only!
4. Proceed to
Installing the Temp Probe
(if applicable) or
Setting up the Transducer on the Control
Head
.
5.
Installing 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 Customer Service 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.
1. 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.
2. 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.
3. Drill a 1/8" mounting hole approximately 3/4" deep.
NOTE:
On 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 coating.
4. Seal the mounting hole with marine-grade silicone sealant, and attach the sensor to the transom using
the provided screw.
4. 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.
5. View the sonar signal on the control head display and compare it against what you 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, continue to step 6. Otherwise, locate a new position in the hull and repeat steps
3 through 5.
6. 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 7. If the performance is not acceptable, repeat steps 3 through 6.
7. Once you have determined the best mounting location using this procedure, mark the position of the
transducer.
3.
Installing the Transducer
1. Mark the location of the transducer and remove the water from inside the hull. Thoroughly dry the
mounting surface.
2. Mix an ample quantity of two-part slow-cure epoxy. Coat the face of the transducer and the inside of
the hull.
3. 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.
Routing the Cable
Use the following instructions to route the cable to the control head or black box sonar, depending on your
system configuration.
NOTE:
Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.
1. Unplug the other end of the transducer cable from the control head.
2. Route and secure the cable, avoiding areas where it may be damaged or interfere with normal boating
operations.
