How to Connect a Humminbird Fish Finder

How to Connect a Humminbird Fish Finder
Using a fish finder or depth finder, like those made by Humminbird, helps maximize time spent on the water as these devices locate schools of fish, letting you know right where to drop a line. Proper use, installation and connection is critical to the correct operation of the device. Connecting Humminbird fish finders is a straightforward process that allows for the use of the gear and equipment.


Difficulty: Moderately Easy

Things You’ll Need:
  • Humminbird fish finder
  • Cable attachments
  • Installation kit
  • Power drill
  • Waterproof epoxy
Step 1
Locate an area between 12 to 15 inches away from the boat engine and prop on the rear of the boat where the draft will be underwater. Drill four holes using the transducer mounts as guides.
Step 2
Set the transducer over the holes and align with the holes on the transducer mounts. Screw in the screws from the install kit with the power drill so the transducer is firmly attached to the boat. Epoxy the four holes on both the inside and outside of the boat. Allow the epoxy to dry to provide waterproofing where the holes have been drilled.
Step 3
Decide if you want the power cable to be mounted externally or internally. Run the cable along the side of the boat and fasten it using epoxy until the cable reaches the transom mount near the boat's cockpit and steering wheel area. Drill a hole large enough for the cable to go through if mounting internally. Thread the cable through the hole and run to the transom mount. Epoxy the hole and let dry.
Step 4
Mount the transom mounts and display screen to the desired location next to the steering wheel. Screw the install kit screws into the transom mount with the power drill. Attach the power cable to the display screen.
Step 5
Attach the transducer and display screen cables to the boat's battery or to an external battery by connecting the negative wires to the negative battery terminal and the positive to the positive.
Step 6
Check that the power is connected by pressing the Hummingbird fish finder's Power button and watching the display screen come on with the default screen settings.
