Installing Seats In An Aluminum Jon Boat: A Step-By-Step Guide

Installing seats in an aluminium jon boat can be done in a variety of ways. One method is to use a clamping system, which is easy to install and requires minimal modification to the boat. Another option is to create a DIY mount platform by reinforcing the boat's existing benches with plywood or aluminium and then bolting the seats to the platform. It is important to consider the stability and security of the seats, as well as the potential for bolts to rip out of the aluminium. Some people also suggest using stainless steel bolts and reinforcing plates to prevent corrosion and ensure the seats are securely attached.

Using interlocking aluminium extrusions

To install seats in an aluminium jon boat using interlocking aluminium extrusions, follow these steps:

First, you will need to source the interlocking aluminium extrusions. These can be purchased from a boat dealer. Ask for two-piece extrusions, with one piece that attaches to the front of the bench and the other that attaches to the seat swivel or directly to the seat. Ensure the piece that attaches to the boat is the full length of the bench, allowing for flexible seat positioning, and the piece that attaches to the seat is only about 8 inches long.

Next, you will need to prepare the surfaces for installation. Clean the bench and seat surfaces, ensuring they are free of dirt, grease, or debris.

Now, it's time to install the interlocking aluminium extrusions. Using pop rivets or sheet metal screws, fasten the longer piece of the extrusion to the front of your boat bench. Make sure this is securely attached before moving on. Then, attach the shorter piece of the extrusion to the base of your seat using pop rivets or sheet metal screws. Ensure that the two pieces of the extrusion interlock securely together.

Finally, you can install your seat onto the bench. Simply tilt the seat all the way forward and lift it straight up to lock it into place on the bench. Your seat should now be securely installed, and you can adjust its position by tilting and lifting it.

This method provides a solid and safe installation, and you can easily remove the seats whenever needed without the hassle of dealing with nuts and bolts.

Drilling holes and using nutserts

Step 1: Gather Your Tools and Materials

Before you begin, make sure you have all the necessary tools and materials. You will need a drill, drill bits, nutserts and bolts, a rivet gun, and a rivet tool. You may also want to wear safety gear such as gloves and eye protection.

Step 2: Mark the Drill Holes

Carefully position your seat pedestal base on the jon boat's bench seat and mark the locations for the drill holes. It is crucial to ensure the holes are correctly positioned and aligned before drilling. Take measurements and double-check them to avoid mistakes.

Step 3: Drill the Holes

Using the appropriate drill bit size, slowly and carefully drill the marked holes. Go slow to prevent any damage to the aluminium and to ensure the holes are clean and precise. Take your time with this step as it is crucial for the stability and security of your seats.

Step 4: Insert the Nutserts

After drilling the holes, it's time to install the nutserts. Nutserts are threaded inserts that will provide a strong and secure connection for your bolts. Insert a nutsert into each drilled hole, ensuring they are flush with the surface. You may need to use a rivet tool to securely fasten the nutserts in place.

Step 5: Attach the Seat

Now, you can attach your seat to the pedestal base using bolts that match the size of your nutserts. Securely tighten the bolts, ensuring they are tight enough to prevent any unwanted movement or loosening over time. You may also want to add lock washers for extra security.

Step 6: Final Checks and Testing

Once your seat is installed, carefully inspect your work. Ensure that the seat is securely attached and that all bolts are tight. Test the stability of the seat by applying some weight and trying to move or wobble it. If everything feels secure and stable, you're ready to hit the water!

Remember, taking your time and being precise with your measurements and drilling will ensure a safe and secure installation. Always follow safety guidelines when operating power tools and working with metal boats. With these steps, you'll have sturdy and reliable seats for your aluminium jon boat!

Clamping systems

If you are looking for a clamping system, there are a few options to choose from. The Attwood and Alumacraft clamping kits are highly rated and reviewed and should present zero problems. You can also use a Wise camo seat, which fits universally into most clamping mounts.

Before installing your clamping system, you should carefully consider your seating configuration and layout. If you don't want to spend a lot of money, you can check out some DIY videos, images, and ideas online. For example, you could use interlocking aluminium extrusions or aluminium "Rivnuts" to fasten your seats. Alternatively, you could bolt your seats to plywood and then attach the plywood to your boat using angle brackets.

Drilling and using bolts

One method to reinforce the seat is to use a piece of plywood as a mounting base. Cut a piece of plywood that is slightly larger than the seat bench. Drill holes in the plywood and bolt the seat to it. Then, bolt the plywood to the aluminium bench. This will distribute the weight and reduce the chance of the bolts pulling out.

Another option is to use interlocking aluminium extrusions that can be purchased from a boat dealer. One piece is fastened to the front of the seat using pop rivets or sheet metal screws. The seat can then be bolted to the other piece. This method allows for easy removal and adjustment of the seat.

If you are unable to access the underside of the mounting surface, you can use "Nutserts" or "Rivnuts". These are inserted into the existing holes and provide a threaded insert for bolts to grip onto. This method is stronger than simply screwing into the thin aluminium.

When drilling and bolting, it is important to use stainless steel bolts and washers. Stainless steel will not corrode and weaken the aluminium over time. It is also recommended to use backing plates or washers to distribute the weight and further reinforce the bolts.

Finally, if you are mounting a pedestal seat, you may need to cut a small hole in the side of the bench to access the bolts. This can be finished with an "edge" guard for a neat appearance.

Using a swivel base

To install seats in an aluminium Jon boat using a swivel base, you will need to follow these steps:

Firstly, you need to decide on the location of the seat. It is recommended to install the middle seat offset to the left and the bow seat centred for better balance and visibility. Mark the position of the seat on the boat.

Next, you will need to cut an access hole in the aluminium bench directly under the seat. This will allow you to access the underside of the bench and install the swivel base. Make sure the hole is big enough to fit your hand and any tools you will need.

Now, you can install the swivel base. One option is to use toggle bolts, which are similar to regular bolts but have a toggle that expands on the other side, providing a secure hold. You can also use rivets, which can be installed with a rivet gun and are quick and secure. If you want the option to remove the seat in the future, consider using toggle bolts instead of rivets.

Another option is to use a swivel seat mount, such as the Attwood SP-67749 Swivl-Eze Lock'N-Pin Aluminium Boat Seat Pedestal Mount. This option uses a 3/4” diameter pin and a 7” x 7” square base, available in aluminium or stainless steel. You can secure the base to the bench using high-strength 1/4” rivets.

Alternatively, you can create a wooden base for the swivel seat by cutting a piece of plywood to fit the bench and using angle brackets to secure it from the side lip. You can then use stainless steel carriage bolts to attach the seat base to the plywood.

Finally, you can attach the seat to the swivel base by placing the seat on top of the base and securing it with nuts and bolts. Make sure to use stainless steel hardware for durability and corrosion resistance.

By following these steps, you can securely install a swivel seat in your aluminium Jon boat, providing a comfortable and functional seating solution.
