How To Install A Fishfinder On A Fiberglass Boat

Installing a fishfinder on a fiberglass boat can be a great way to enhance your fishing experience. However, the process can be daunting if you’re doing it for the first time. In this article, we’ll provide you with a step-by-step guide on how to install a fishfinder on a fiberglass boat.

Choose the right fishfinder for your boat:

Choosing the right fishfinder for your boat can make a significant difference in your fishing experience. Factors to consider when selecting a fishfinder include the size of your boat, the type of fishing you plan to do, the features you want, and your budget. Some fishfinders come with advanced features like GPS and chart plotting, while others are simpler and more affordable.

Gather the necessary tools and equipment:

Before you begin installing your fishfinder, you need to gather the necessary tools and equipment. Some of the essential tools include a drill, jigsaw, silicone sealant, screws, a mounting bracket, a fishfinder, a battery, and a transducer. It’s important to have all the tools and equipment you need before you begin the installation process to prevent interruptions and ensure that the installation goes smoothly.

Find the best location for the fishfinder installation:

The location of your fishfinder installation is critical for accurate readings. You need to choose a location that’s free from obstructions, where the transducer is submerged in water, and where the fishfinder screen is visible. It’s also important to choose a location that’s easy to access for maintenance and repairs. Common locations for fishfinder installation include the transom, the hull, or the trolling motor.

Install the mounting bracket:

Once you’ve found the best location for your fishfinder, you need to install the mounting bracket. You’ll need to drill holes in the bracket and then apply silicone sealant before screwing it to the boat. The mounting bracket holds the fishfinder and transducer in place and ensures that they stay securely attached to the boat.

Mount the transducer:

Mounting the transducer is a crucial step in installing a fishfinder. You need to apply a generous amount of silicone sealant on the transducer and press it firmly against the hull of the boat. The transducer sends and receives sonar signals, which are essential for providing accurate readings of fish and the underwater terrain.

Install the fishfinder and connect the wiring:

Once the transducer is mounted, you need to install the fishfinder and connect the wiring. Follow the manufacturer’s instructions carefully to ensure that you connect the wires correctly. It’s essential to use marine-grade wires to prevent corrosion and ensure that the fishfinder works correctly.

Test the fishfinder:

After completing the installation, you need to test the fishfinder to ensure that it’s working correctly. Take the boat out on the water and test the fishfinder’s accuracy. You can do this by looking at the fishfinder screen and comparing the readings to what you see in the water. Testing the fishfinder ensures that it’s providing accurate readings and that you’re ready to catch more fish.

In conclusion, installing a fishfinder on a fiberglass boat can be a great addition to any angler’s toolkit. By following the steps outlined above, you can ensure that the fishfinder is installed correctly and providing accurate readings. Choosing the right fishfinder, gathering the necessary tools and equipment, finding the best location for installation, installing the mounting bracket and transducer, connecting the wiring, and testing the fishfinder are all essential steps that should not be overlooked. Taking the time to properly install a fishfinder can improve your fishing experience and help you catch more fish.

How do you attach a fish finder to a fiberglass boat?

Attach the fishfinder using a mounting bracket and silicone sealant, choose a location for the transducer that’s free of obstructions, mount the transducer using silicone sealant, and connect the wiring correctly.

Can a transducer shoot through fiberglass?

Yes, a transducer can shoot through fiberglass if it’s installed correctly.

Where do you mount a fish finder on a boat?

The best location to mount a fishfinder on a boat is in a place that’s free of obstructions, where the transducer is submerged in water, and where the fishfinder screen is visible.

How do you install a transducer inside hull?

To install a transducer inside a hull, you need to drill a hole in the hull, apply marine-grade epoxy to the hull and transducer, and then mount the transducer inside the hole.

How do you anchor into fiberglass?

To anchor into fiberglass, you need to use a special anchor designed for use on fiberglass boats and follow the manufacturer’s instructions carefully.

Should the transducer be below bottom of the boat?

Yes, the transducer should be mounted below the bottom of the boat to prevent air bubbles from interfering with the sonar signal.
