Learning how to install a fishfinder can help you find the correct way of running and installing it. It is a good idea to put in little extra time and efforts into the work and ensure that installation is done appropriately. To enable users to do the task appropriately we have brought forth installation steps in brief below.
This is one of the most important steps of installation and should be executed appropriately to achieve best results. Most of the transom units are easy to install, all you need is some tools from your garage and shed and you can get on with the work by yourself. However, if you have opted for the thru-hull unit, then it is advisable that you approach a professional for the job. During the installation of this unit, a hole has to be cut out at the bottom of the boat; this task can be easily carried out by professionals without any fault or mistake.
#2, Placement of Wires
People often argue about the placement of wires, but it is not at all a thing to worry about. The very first thing to do before placement of wire is the installation of the unit. Once the installation has been done, space can be carved out for putting the wires neatly.
#3, Look for a Submerged Spot
For appropriate installation, you would need a submerged spot on the body of the boat. It is essential that your transducer all the time remains in contact with the water to function properly. Hence this factor should be given due consideration and then only the process of installation should be started. While carrying out this step also make sure to find out how smooth the transom part is and how much distance will keep the unit in workable condition. One should ensure that no disturbance is caused to the unit; else it might have an impact on its functionality.
#4, Position of the Unit
Before beginning with installation, it is important to consider the exact place where transducer should be placed. While looking for the place, one should keep in mind that it does not get bumped after being installed in the boat. Placing transducer horizontally is an apt position for the fishfinder.
#5, Run the Wires and Test it
Before the installation of wires is actually done it is feasible to test and run the wires from the main unit and also to the battery. This step should be carried out before screwing, else an accident might compel the installer to reinstall the unit and loosen the screws and holes placed.
If in case the wire attached to your unit is a bit long, you should never ever think of cutting them. This might end up manufacturer’s warranty and I am sure you would never want this. Instead of cutting, coil or clamp the wires and fasten them to the tiles near the unit. However, make sure that clamping should never be done near transducer.
#7, Now Mount the Transducer
Once you have been successful in finding a good place for your unit, stick plastic block over it. This shall enable you to mount the transducer conveniently without having to drill extra holes at the place. To ensure that strong installation is done, give some time to the adhesive or glue to stick block strongly against the tile.
#8, Drilling the Transducer
Now place the transducer over the block and mark positions with a pencil. Pencil marks are the place wherein installation of unit needs to be done. If you are thinking of installing transducer directly on the transom, mark two holes and then drill them. Use the mounting hardware to screw transducer and apply a good amount of silicon or adhesive both inside and outside to place it. this sort of fixing will enable you to ensure that no water flows out of the hole and believe me this is one of the most important things to keep in mind and consider.
#9, It is Time to Run the Wires
Once the process of mounting has been completed, it is now time to actually run the wires. This step can be carried out in two ways i.e.;
- Above the transom
- Through the hole of transom
If in case you are drilling a hole in the transom, make sure to do the drilling above the water level. While running the wire, one must make sure to keep the wires secured by clamping them against the tiles after every 18 inches. This way the wires remains protected and also save the installer from any incident later on.
Once wires have been drilled and ran through, make sure to keep the terminals disconnected. This will complete your installation and shall also give you the freedom to place your kind of connectors as and when required.

#10, Mount the Fish Finder
By now you are almost done with the job of mounting the unit, running wires through it and attaching fishfinder to the power unit. Finally, it’s time for you to mount the fishfinder and get done with your job of installation. However before actually mounting look for a convenient place for the same. If your boat has a dashboard, use the optional in-dash mounts to place the unit. Once you have tracked the area, mark it with pencil carefully and get on with drilling. Make sure that you don’t cut the portion too much else it would be impossible for you to fix the fishfinder. No matter you choose a simple unit or a Garmin fishfinder GPS combo same steps should be carried out for mounting.
#11, Done with the Job, Now Enjoy
If you have carried out the steps mentioned above effectively and also given enough time to the sealant to dry, its time you take out your boat into the water and get on with the fishing experience. To have an everlasting experience make sure to follow each and every installation step and also invest in best fishfinder after going through Garmin fishfinder reviews.
