You’re likely to need nuts, bolts, and washers. Make sure they’re stainless steel to prevent rust. You can remove the sides of the boat easily to get full access, and snake wires through.
How to Install Fish Finder on a Kayak
Kayaks like the Vibe Sea Ghost have space for a fish finder on a RAM ball mount. There’s also a hole for the transducer cable in the cockpit and space for the battery.
How to Install Fish Finder on Trolling Motors
Clamp the transducer to the trolling motor with a stainless steel clip. Wrap it around the motor housing and fasten it there. Make sure to leave slack for depth adjustment.

People Also Ask (FAQs)
Is it hard to install a fish finder? How long does it take to install a fish finder?
Installing a fish finder can be more complicated if the device is more sophisticated. Generally speaking, it’s a simple task if you’re already handy with power tools and can be done in an hour or two. It’s easier with a mounting plate; if you aren’t so handy, it may be best to hire a professional.
How do I install depth finders?
Depth finders use technology the same or very similar to fish finder transducers, so the installation is more or less the same. In fact, the best fish finders include depth finders in their design to avoid installing two different devices.
How do you install a fish finder on the bow?
To mount a fish finder on the bow, it will be most effective to run the power wires to the cranking battery. Use an inline fuse to prevent a power surge and give yourself an easy way to change the fuse when needed.
How to binnacle mount a fish finder?
Drilling holes for a binnacle mount is low-pressure because the mount itself will usually cover them up. Make sure to get all the wiring and installation work completely finished, then slide the mount over everything. Attach the fish finder itself only after the mount is successfully installed.
Conclusion
Fishfinders are a crucial piece of equipment for anglers who want to be strategic and reel in lots of fish. Installing a fish finder can be intimidating, but it can be accomplished with the right tools and knowledge of how and where to mount the transducer.
