How To Install A Fishfinder? A Step By Step Guide


All electrical equipment needs instructions for easily using them. Just like other electrical tools the fish finder also needs the right and exact information that will help to install the fish finders easily which makes your life more reliable before finding the fish in the water.

We mentioned the many different ways to mount the transducer of the fish finders. The mounting binnacle fish finder is also a good type that helps to locate the exact position of fishes. We need cable wires, fuse blocks to maintain the power, and many basic tools to use the fish finders easily.

Basics Of Fish Finders

The basics of fish finders enable us to know how fish finders work and how their important elements function that are connected inside them. In an easy pattern, they used the sounds and found the objects present in the water.

The transducer present inside them works to transmit the pulses. These sonar waves beat the object and again reflect these pulses. The display screen is a part of the fish finder that shows these pulses in the form of colorful images of the objects.

The fish alarm, GPS connectivity, and other accessories give many benefits that find the fish quickly. This electrical tool is available in all sizes and features that save your time and money.

Supplies & Tools You Need To Install A Fishfinder

Several tools exist in the market that we need for the installation of fish finders. 

Many tools are necessary to install them such as:

05 Steps To Install A Fishfinder

05 Steps To Install A Fishfinder

Step # 1: Flush Mounting The Fish Finder

The flush mounting phase helps to manage all the settings in an easy and same plane. This type also increases the quality of your boat. The thick and high-value panel gives easy viewing images. This panel is mostly found in fiberglass materials which are easy to cut and drill that you need for opening.

To fit the panel in a flush mounting fish finder you need the right size of the panel and cut them inches with two larger than that of opening. You adjust the exact sized panel with mounting screws. You should need the piece of gear for design and arrange them properly.

Moreover, mark the panels and cut them in rectangular shape and with the help of drill compares the corner radius. Also, remember that drilling in a fiberglass panel is slightly harder than fiberglass over wood. Several fish finders want a full flush mounting kit for a more easy way of installation.

Step # 2: Installing The Binnacle Mount 

To install a fishfinder in binnacle mounting form you need the right place to mount this device. You should make an effort to maintain the finder as near as possible in the middle of the helm. Due to closeness, your angle for viewing all things occurred very adequately.

Without using the campus, throttle, or many affixed things, you easily turn on the device that will further allow the location feature. You should hold the fish finder at some height and check the progress of viewing the display correctly.

When you find the place for fixing the binnacle mount, also examine the space that you select for wiring. Then make sure the fish finder easily rotates in all directions and gives all images with spotted areas perfection.

After that the marked locations drills and holes for screws on with the templates of binnacle mount adjustment. The holes are large due to fixing the cable that is covered with silicone sealant holes and connecting them as the proper instruction for binnacle mount requires. 

Step # 3: Routing The Power Cables

Firstly you need the perfect size of wire or cable for routing them. They also depend on the length of power cables so if you need the larger power code make sure you attach them with color coding and tinned copper cable (wire).

The connection of cables is usually made with a crimped barrel that is safe when you adjust them in holes drill structure. You can save your power cables at a distance of about 18 inches and cover them with tie wraps and cushioned clasps.

The fuse blocks have mainly two kinds: the male spade terminal and the female spade terminal. They were connected at the end of them and also protected this connection with heat shrink tubing.

You can remove this terminal if the installation is completed. The connection of the cranking battery is also a part of the power cable of fish finders. The trolling motor battery provides energy and fulfills the requirements when you start the boat.

Step # 4: Installing The Transducer

For the installation of fish finders, you also need the installation of a transducer for the best option. Before this installation, you find the best spot for searching things. Find a deep area with no strakes, through-hull fitting with a smooth hull in front of this.

Like if things offend the flow of water the fish finder shows bad performance. When you establish the exact spot you hold the transducer bracket opposite to the transom hull and also determine their position horizontally.

Mark the location of brackets mounting holes and adjust the transducer wiring in such a way you easily cut off at the end of the transducer and use them to draw the wiring system. Then marking spots fix due to screws with the power drill and make them ready for good installation of the transducer.

Also, remember to use the sealant to liberally coat the mounting screws and holes that allow the water to moisten is a good feature.

Step # 5: Test Run

For good use of sealant, you need 4 days to dry them appropriately. Due to this dryness and seal out holes become moisture quickly. You can carry the fish finder for out fishing just when the sealant is properly dried. You need correct keys to get all the clues quickly performed.

When the transducer is not attained in the water as we can say that it can’t fulfill the requirements for using them perfectly in the water the results become that you don’t get any signal. Firstly the good tip is that you protect all the connections due to rubbing their liquid from electrical tape.

Also if your wires are minor long, don’t cut them because the clamp for wires is the main point. Make sure don’t use the transducer wire with engines wiring harness due to this interference they cause complications during fishfinder performance. This shows how you can install the transducer and fish finder in the right way.

How To Install A Fishfinder In:

1) Kayak


The method we can use to install a fishfinder on a kayak requires different components. The best fishing kayak is manufactured with unique accessories to adjust the transducer, circuit wires to the battery, and display.

You can install fish finders on kayaks easily because they are set up with instructions for using them and all electronic features for our comfort fulfill their requirements. For stronger mounting of the display screen on the kayak with gear, the track gives more versatility.

Using silicone adhesive you mount the transducer inside the kayak hull easily. Also, maintain all the route cable holes with high power battery connection and you remove the display and battery easily.

2) Jon Boats

Jon Boats

The installation of a fishfinder on Jon boat is very easy and you can use them for bass boats. Most anglers install two fish finders. The reason is that one is set up near the driver’s seat and one is adjusted on the bow near the trolling device.

For installation of the display screen, you need a versatile ability for mounting them and also use standard bases. After the set up of the display, attach the transducer to the transom, line up the water level for receiving and sending signals. The good thing is that you can secure transducer wires with consuming tabs. Attach all the power cables with the battery and follow the instructions. 

3) Center Console Boats

Center Console Boats

We searched and noticed that the installation on the center console is very similar to the installation on Jon boat. Anglers preferred to install the transducer to the transom with the attachment of cables that provides proper signals.

In center console installation, a through-hull transducer gives outstanding sonar images. After the mounting of the transducer, make the route for wire and to the display. In the center console, you have many choices for setting the display screen such as installing the display on the gear track. The design of center console boats allows mainly flush mounting because they protect the backside of the display screen.

Final Thoughts

The BS Reviews explained all the knowledge that is relevant about how you can install the fish finder. In this post, how to install a fishfinder on a kayak, Jon boat, and the center console is clarified in detail and also the mounting of the transducer in the right way is mentioned.

We also referred to many tools that are available in the market for help to install the fish finder quickly.
