Getting Your Kayak Ready for a Fish Finder: The Mounts You Need

Mounting a fish finder on your kayak transforms your fishing experience. It gives you a clear view of what’s happening below the surface. This guide will walk you through the common methods. You’ll learn how to securely attach both your transducer and your display unit. We’ll cover everything from choosing the right mount to the final tightening of screws. Let’s make sure your fish finder stays put, even in choppy water.

Choosing Your Kayak Fish Finder Mount Type

The first step is selecting the right kind of mount. Your choice depends on your kayak’s design and where you want your screen to be. Many anglers find that a combination of mounting solutions works best. We’ve looked at the most popular options available.

Rail-Mounted Systems

If your kayak has a built-in rail system, you’re in luck! Rail mounts are incredibly versatile and adjustable. You can easily slide them into place and tighten them down. This makes repositioning your fish finder a breeze. Many kayak manufacturers include these rails for accessories. If yours doesn’t, you might consider adding one. Rail systems often allow for a lot of flexibility in where you position your gear.

Pad-Eye and Track Mounts

Some kayaks use pad eyes or small tracks for attaching accessories. You can find mounts that screw directly into these. These are often simpler and more permanent than rail systems. They might require drilling into your kayak if you’re adding new mounting points. Always double-check the kayak’s manufacturer recommendations before drilling. We found that using marine-grade sealants is key to preventing leaks.

Suction Cup Mounts

For a quick and easy setup, suction cup mounts are popular. They attach to smooth, flat surfaces on your kayak. These are great if you don’t want to drill holes. However, they can lose suction in very cold water or if the surface isn’t perfectly clean. We found that regular cleaning of both the suction cup and the kayak surface is essential. They are less permanent but convenient for quick trips.

Direct Bolt-On Mounts

These are the most secure but require drilling. You’ll typically bolt a small plate or bracket directly to your kayak’s deck. This plate then accepts a mount for your fish finder or transducer. This method offers maximum stability. Many anglers prefer this for its reliability. You need to be confident about drilling into your kayak. Proper sealing is a must to avoid water intrusion.

Where to Position Your Fish Finder Display

Placing your fish finder screen is all about visibility and accessibility. You want to see it clearly without taking your eyes off the water for too long. Most anglers prefer a spot within their line of sight while seated. This might be in front of their console or beside them.

Forward-Facing Mounts

These mounts position the screen directly in front of you. This offers the most convenient viewing. You can glance down easily to check readings. Many rail systems allow you to attach a specific fish finder mount that swivels. This lets you adjust the angle for comfortable viewing. We found that a mount with a flexible arm is often ideal here. It allows for fine-tuning the position.

Side-Mounted Options

Some anglers prefer to mount their fish finder off to the side. This keeps your forward view completely clear. It can be useful on kayaks with limited console space. Side mounts can attach to existing tracks or pad eyes. Ensure it’s not so far to the side that it becomes a distraction or obstruction. Think about where your paddle strokes will go.

Mounting Your Fish Finder Transducer

The transducer is the ‘eye’ of your fish finder. It sends and receives sonar signals. Proper placement is critical for accurate readings. You want it submerged in the water without obstruction. Many experts suggest avoiding areas with a lot of turbulence.

The Best Transducer Mounting Locations

Where you mount your transducer matters for signal clarity. The goal is to get a clear, unobstructed view of the water below. We found that some locations are consistently better than others.

Inside the Hull (Shoot-Through Mount)

For kayaks made of polyethylene or other similar plastics, mounting the transducer inside the hull is an option. You’ll need to create a seal using silicone or epoxy. The sonar waves pass through the hull material. This method protects the transducer from damage. However, it can sometimes lead to weaker signals. Thicker hulls or air bubbles in the sealant can interfere. Many manufacturers recommend this for certain hull types (e.g., Old Town).

Transom Mounts

If your kayak has a small transom area, a transom mount is a good choice. This bracket clamps onto the edge of the kayak. The transducer then hangs down into the water. It’s a relatively easy setup. Just ensure it doesn’t interfere with your paddling. We found that checking for obstructions in the water is key with this type. Debris can easily snag a hanging transducer.

Kayak-Specific Transducer Mounts

There are many commercially available kayak-specific transducer mounts. These often attach to the hull and extend down into the water. Some are flush-mounted, while others are on retractable arms. This offers a good balance of protection and performance. Many are designed to be deployed and retracted easily. This is a great option if you plan to paddle in shallow areas.

Using a Trolling Motor Mount

If you have a trolling motor mounted on your kayak, many transducers can be attached to the motor shaft. This is often a secure and stable solution. Ensure the mount is designed for your specific transducer model. Always check that the transducer won’t impede the motor’s function.

Wiring and Power Management

Once your units are mounted, you need to consider the wiring. Most fish finders come with power cables and transducer cables. You’ll want to route these neatly to avoid snags and keep your deck clear.

Securing Cables

Use zip ties or cable clips to secure the wires along the kayak’s hull or any existing rigging. This keeps them tidy and prevents them from getting in your way. Look for areas where the cables can run without being stretched or kinked. We found that running cables along the inside edge of the kayak often works well.

Power Source

Fish finders require power. Most anglers use a small, sealed 12-volt battery. You can place this battery in a dry bag or a dedicated battery box. Many kayaks have storage hatches where a battery can be secured. Ensure the connection points are protected from water. Some advanced setups use integrated power systems. For most casual users, a simple battery is sufficient.

Final Checks Before Hitting the Water

Before you launch your kayak, take a moment for final checks. Give your mounted fish finder a gentle wiggle. Ensure all screws are tight and all mounts are secure. Check that the transducer is submerged correctly and the cables are out of the way. A little attention now can prevent a lost unit or a frustrating day on the water. We found that a quick visual inspection and a firm tug on the mount are usually enough.

Conclusion

You’ve learned how to securely mount your fish finder, transforming how you fish from your kayak. We covered different mount types, from versatile rail systems to drill-free suction cups. We also looked at the best spots for your display and the critical placement of your transducer for accurate readings. Don’t forget proper cable management and a reliable power source. Taking these steps ensures your fish finder works effectively and stays put. Your next trip out will be much more successful with your new setup. Go ahead and mount your fish finder; you’re ready to find more fish!

Frequently Asked Questions

How do I know if my kayak is compatible with a specific fish finder mount?

Check your kayak’s manual or manufacturer’s website for existing rail systems, track mounts, or pad eyes. If you plan to drill, consult the manufacturer about recommended mounting locations and hull material. Many universal mounts are available, but confirming compatibility prevents installation issues.

Can I mount a transducer inside my kayak without drilling?

Yes, for polyethylene kayaks, you can use a “shoot-through” mount. You’ll need to create a sealed compartment on the inside of your hull and place the transducer inside, with sonar signals passing through the hull. Ensure there are no air bubbles trapped in the sealant for best results.

What’s the biggest mistake people make when mounting a fish finder?

A common error is not securing the mount tightly enough, leading to a wobbly screen or a lost unit. Another mistake is poor transducer placement, causing inaccurate readings due to turbulence or obstructions. Always double-check your work before launching.

How do I protect my fish finder and transducer from damage on a kayak?

Consider using kayak-specific mounts that are retractable or can be easily removed. Mounting the transducer inside the hull offers excellent protection. Secure cables to prevent them from snagging on underwater obstacles or your paddle.

Do I need a special battery for my kayak fish finder?

Most kayak fish finders run on a 12-volt battery. A small, sealed marine battery is ideal and can be placed in a dry bag or battery box. Ensure all connections are waterproof and secure. You don’t typically need an overly complex power system.
