If the boat has a circuit board, connect the power line to one of the free outlets. If the motor runs directly off a volt battery, attach the power cable to the battery with an inline fuse. The optimal set-up on a small boat places an additional display on the bow. Networking the second display to run through the transom transducer is easy, but attaching a second transducer to the trolling motor offers another view of structure and fish.
Attaching a sideview transducer to the trolling motor offers a clear image without turbulence. Liveview sonar requires the transducer to turn in the direction of the target. Connecting the transducer to the trolling motor allows the transducer to turn with the motor for a degree view around the boat.
Installing a fish finder in a center console is similar to installing a fish finder in a Jon boat. The easiest option is to attach the transducer to the transom and run the cable over the stern. For the best sonar image, anglers with center consoles install a through-hull transducer. These transducers mount under the boat with the cable running through the hull. There is an uninhibited signal and return since a through-hull transducer is ahead of the motor and away from turbulence.
Since this installation requires a hole in the boat hull, we recommend a professional do the job. There are many options for positioning the display unit. In addition to installing the display on a gear track or factory bracket, many center console boats are designed to allow the fish finder display to be flush mounted to the console. To flush mount the fish finder screen, use the template included with the instructions.
Cut the outline of the display and tape it in place on the console. Be sure there is clearance for wires behind the panel. Tape around the template and use a handheld jigsaw or similar saw to follow the line. With the transducer and display in place, connect the power cord to the electrical panel.
Use mount head cable ties to route the cables to the display unit. Modern electronics are plug-and-play. After installing the parts and running the cables, turn on the unit and go fishing.
Before starting the installation, remember the old adage: measure twice and drill once. And there should be enough space for the wiring. You should also ensure that the fish finder can be easily tilted or rotated in the spot for viewing without obstructing other controls. This should help you decide on a fixed location. Now bring out the template provided with the binnacle mount for affixing it. Or else, you can just place the binnacle mount at the selected location and mark the point for drilling holes to screw it on.
You will have to mark one more hole for the exit point of the wires. Double-check that this hole is large enough for the clump of wires that should pass through it. Once the holes are marked, run the power drill at full throttle for a clean hole.
Slow drilling and hesitation will cause the surface to splinter. Shoot some sealant on all the holes. Pull out the clump of wires that should connect to the fish finder to fix them later.
Now on to installing the fish finder mount. You can fix the mount and screw it in with the accompanying stainless steel bolts. The finish of the bolts is important to avoid corrosion.
Fasten each bolt with an aircraft nut and a stainless steel washer for a tight fit with the wrench that came with the fish finder. Squirt more sealant on the bolts after this to completely seal them off against moisture.
Next, you must attach the wires to the designated plug head of the fish finder. This plug head should be placed on the base of the binnacle mount. Once these are properly affixed, you would know what length of connecting cable should be above the surface from the cable hole. Stick duct tape under the mounting region and cut out a hole in it around the cable hole.
From the top of the surface pour some silicone sealant around this cable hole. The duct tape keeps it from dripping below the helm. If you have a quick-release mount, you can fix the fish finder on it and you are done with this part. If the fish finder is more permanently affixed to the mount, you might have to struggle to pour sealant around the cable hole.
Wiring up marine electronics is a whole science in itself. There are two major ways of powering the fish finder: cranking battery and fuse blocks. Many official sources recommend connecting to the starting or cranking battery of the vessel.
This is the battery that provides short bursts of power for the ignition switch to be activated and the engine of the vessel to start. Once the boat starts, it requires continuous energy which is provided by a separate trolling motor battery. Most of the light electronics with low power draw are connected to the cranking battery directly with inline fuse. The trick to keeping the battery and battery-powered equipment like fish finders safe is to install an inline fuse. The inline fuse should be installed on the positive lead as close to the battery as possible.
This way, in case of a short, only the piece of cable between the battery and the fuse will be fried. And the rest will remain intact. Hooking up the fish finder directly to the battery works well only if you use the right gauge of cable to connect the two.
This depends on the length of cable required to connect the two and the amp draw of the fish finder. Most boats now come equipped with at least one fuse block. Below you will see two fuse blocks. The main fuse block is left for important devices. The smaller ones like the one below can be used to hook up accessories with low draw like the fish finder. A fuse block can be used to distribute power amongst the various circuits on the vessel.
Yet, pro-fuse block anglers argue that it cannot cause any more interference than multiple leads connected to a battery post directly. Check out the electricity draw of your fish finder. Usually fish finders draw 1. The best way to use additional fuse blocks is to connect them to the cranking battery. You can use marine-grade fuse holders at the battery to protect these connections. These dual cable also have a protective covering which fares well against chafing and external elements.
For the fish finder, we suggest mounting a fuse block under the console. Use stainless steel nuts and bolts in the process. Choose such a location to mount the fuse boxes that they are protected from the elements but accessible for repair. You may be wondering how to get the wiring in your dash. Never fear, we have you covered! Run the wire for your transducer through and coil it up with clamps so nothing gets tangled or snagged on anything. Drill the holes in a way that will allow you to screw them closed tightly.
If you are not happy with this guide then watch this video to Mounting Transducer in Fiberglass boats. This will keep water out while still allowing for easy access when it comes time to make connections. With all of those wires pulled through and connected properly the last step too. Installing a fishfinder can be time-consuming but it is worth the effort.
It may take some trial and error to get your unit working, so make sure you consult any appropriate manuals before installing anything incorrectly or doing something that will damage your system in the process. A transducer can be mounted inside a fiberglass boat, but it is important to drill vent holes near the edge of the hole in order for water pressure on top and bottom surfaces to not cause damage.
The transducer is placed inside of a clear plastic bag that has been partially filled with water. The wire tie is used to tighten the top and the bottom together so there are no leaks in between, then attach it securely on your boat or kayak hull surface. It is important to place the transducer high enough on the boat for its signal strength and low enough that water pressure does not damage the unit.
In conclusion, it is important to remember that installing a fish finder on a fiberglass boat takes time and patience. The process can be completed with the right tools and knowledge of how to work with these materials. Those who are interested in fishing or boating should consider this before they purchase their next vessel for whatever reason.
Hey, I am Biplob, I have been keeping fishing as my passion for many years. I really believe that fishing will get more popular as a passion and career in the upcoming years.
