NOTE: The transducers shown below
have no directional bias.
Installation
The trolling motor transducer is designed to mount on the trolling motor of your boat. All hardware needed for
installation and operation of this Humminbird® accessory is either included with this accessory or came with your
original transducer. The trolling motor mounted transducer allows you to gather sonar information from the point on
the boat closest to where you are fishing. It is important that you properly orient the transducer housing in the
direction of travel of the trolling motor, to ensure an accurate depiction of the terrain under your boat.
The trolling motor mounted transducer will fit any standard trolling motor housing. Some users install this transducer
in conjunction with a switch so that the standard transducer can be used for high-speed operation, and the trolling
motor transducer can be used while trolling.
1. Attaching the Transducer
WARNING! Before attaching the transducer to the trolling motor, confirm that the motor is disconnected from all sources of
electrical power.
CAUTION! Before attaching the transducer to the trolling motor, make sure the trolling motor is properly secured to the boat
and will not shift during transducer installation.
1. Position the transducer on the underside of the motor housing. Refer to the illustration that most resembles your
accessory, noting any requirements for directional bias.
NOTE: Round, circular-bottomed transducers have no directional bias, and therefore orientation of these types of
transducers is not as important. Rounded rectangular transducers, however, do have a directional bias, and must be
installed as shown in the illustration.

NOTE: The transducers shown below
have a directional bias, and therefore
need to be oriented according to
the illustration below.

Transducer should be mounted forward of the motor shaft. Styles of transducer may differ from illustration.

2. Insert the hose clamp through both openings on the top of the transducer and pull the two ends up around the
motor housing. As you tighten the hose clamp, check to make sure that the transducer is properly aligned with
the motor housing.
3. After tightening the hose clamp, make sure that the transducer is securely attached to the motor housing and
will not slip off while in operation.
2.Routing the Cable
The transducer cable has a low profile connector which must be routed to the point where the control head is
mounted. There are several ways to route the transducer cable to the area where the control head will be installed.
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. Make sure that the cable is long enough to
accommodate the planned route.
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' (15 m). For assistance, contact the
Customer Resource Center at humminbird.com or call 1-800-633-1468 for more information.
2. Routethe transducer cable around the side of the motor housingand secure it to the motorshaft using the plastic
cable ties which have been provided.

NOTE: As you route the cable from the trolling motor to the boat, be sure to leave sufficient slack in the cable to allow for
full movement and retraction of the trolling motor during normal operation.
3. Route the transducer cable to the control head.
3.Connecting the Cable
Insert the transducer cable into the appropriate terminal slot. The cable connectors are labeled, and there are
corresponding labels on the cable holder on the rear of the control head. The slots are keyed to prevent reversed
installation, so be careful not to force the connector into the holder.
4.Test and Finish the Installation
When you have installed both the control head and the trolling motor transducer, and have routed all the cables, you
must perform a final test to verify installation. Testing should be performed with the boat in the water, although you
can initially confirm basic operation with the boat out of the water.
NOTE: Make sure the trolling motor is re-connected to the power source before performing this procedure.
1. Press POWER once to turn the control head on. If the unit does not power-up, make sure that the connector
holder is fully seated in the receptacle and that power is available.
2. If all connections are correct and power is available, the Humminbird® control head will enter Normal operation.
NOTE: The transducer must be submerged in water for reliable transducer detection.
3. 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. If the bottom is visible on-screen
with a digital depth readout, the unit is working properly.
Your control head is now ready for operation.
