Measuring and Cutting the New Transom

After you have removed the old transom and inspected the frames and stringers, it is time to measure and cut the new transom.

Before you begin, you should consider what type of wood you are going to use for the transom.

Plywood is a common choice for many types of boats, but there are other options such as mahogany or teak.

You will also need to consider if you want to use a single piece of wood or if you are going to use multiple pieces.

To measure the new transom, you will need to measure the length and width of the area where the transom will be installed.

You should also add a few extra inches to ensure that you have enough material to work with.

For most jon boats, the transom should be at least five inches thick.

Once you have measured the new transom, you can cut it to size using a circular saw or a jigsaw.

Be sure to wear safety goggles and a dust mask when cutting the wood.

You should also wear gloves to protect your hands from splinters.

When cutting the wood, you should make sure that the cuts are straight and precise, so that the transom will fit perfectly.

After the new transom is cut to size, you can sand it down to make sure the edges are smooth.

You can also use a router to create a beautiful beveled edge.

Once you are happy with the shape and size of the transom, you can move on to the next step of the process securing the transom in place.

Securing the New Transom with Epoxy

Securing the new transom with epoxy is an essential step in the process of replacing a jon boat transom.

Marine-grade epoxy is a waterproof and durable adhesive that is specifically designed for use in marine applications.

It is important to use marine-grade epoxy as it is designed to withstand the harsh conditions found in marine environments.

The first step to securing the new transom with epoxy is to prepare the surfaces that will come into contact with the epoxy.

This includes the transom, the hull, and any gaps between them.

It is important to ensure that all surfaces are clean and free of dirt, grime, and debris before applying the epoxy.

Once the surfaces have been prepared, the next step is to mix the epoxy according to the manufacturer’s instructions.

Make sure to mix the epoxy thoroughly before applying it to the surfaces.

Be sure to use enough epoxy to completely fill any gaps between the transom and the hull.

Once the epoxy has been applied, it is important to allow it to cure completely before moving forward with the next step.

Depending on the type of epoxy being used, this can take several hours or even days.

Once the epoxy has cured, the new transom is now securely attached to the jon boat.

It is important to note that the epoxy is designed to hold the transom in place, but it is not designed to provide structural support.

If the transom is not properly attached to the stringers, it is possible for the transom to become loose and eventually fail.

To ensure that the transom is secure, it is important to use screws, bolts, and washers to attach the transom to the stringers.

This will help ensure that the transom is strong and secure.

Filling Gaps with Epoxy

When replacing a jon boat transom, it is essential to fill any gaps between the transom and the hull with marine-grade epoxy.

This will ensure that the transom is securely attached to the boat and will provide a waterproof seal to prevent water from entering the boat.

To fill the gaps with epoxy, you will need a putty knife, a small mixing bowl, a brush, and of course the epoxy.

Start by mixing the epoxy according to the manufacturers instructions.

Once the epoxy is mixed, use the putty knife to apply it to the gaps.

Use the brush to spread the epoxy evenly and to ensure that it is completely filling the gaps.

Allow the epoxy to dry for at least 24 hours before reinstalling the transom.

When applying epoxy, it is important to wear protective gear such as gloves, goggles, and a respirator.

Epoxy is a strong adhesive and can be difficult to remove from skin and clothing.

Additionally, epoxy fumes can be hazardous, so it is important to work in a well-ventilated area.

Once the epoxy has dried, you can move on to securing the transom with screws, bolts, and washers.

This will ensure that the transom is securely attached to the boat and will prevent it from coming loose or shifting in the future.

Securing the Transom with Screws, Bolts, and Washers

Securing your new jon boat transom is a crucial step in the replacement process, as it ensures that the transom is strong and secure.

To do this, you will need to use screws, bolts, and washers to hold the transom in place.

When selecting the screws, bolts, and washers, you should choose stainless steel hardware that is corrosion resistant and designed for marine use.

This type of hardware is designed to withstand the elements and will be less likely to corrode or rust over time.

You should also choose screws and bolts that are the correct size for the transom and the frames.

Once you have the correct hardware, you can begin to secure the transom to the frames.

Start by drilling pilot holes in the frames for the screws and bolts, and then use the washers to ensure that the screws and bolts are properly aligned.

Once the screws and bolts are in place, use a wrench to tighten them securely.

Finally, you should inspect the frames and transom to make sure that everything is secure and that there are no gaps between the frames and the transom.

If there are any gaps, you can use marine-grade epoxy or caulk to fill them in.

This will help to ensure that the transom is strong and secure, and will help to prevent any water from entering the boat.

Following these steps will help you to securely install your new jon boat transom.

It is important to remember to use corrosion-resistant hardware and to make sure that all of the screws and bolts are securely tightened.

Additionally, make sure to inspect the frames and transom for any gaps, and use epoxy or caulk to fill them in.

Doing so will help ensure that your new transom is strong and secure.

Finishing the Installation

Once the new transom is in place, the final step is to secure it to the stringers.

This is done with screws, bolts, and washers.

It is important to use stainless steel hardware for this step as it is more resistant to corrosion than other metals.

Start by drilling pilot holes into the stringers and then use the screws, bolts, and washers to secure the transom.

Depending on the size and type of boat, you may need additional hardware such as brackets, cleats, or backing plates.

Be sure to use marine grade epoxy to seal any fasteners and to ensure a long-lasting bond.

Once the transom is firmly secured, you will want to inspect the hull and transom for any gaps.

If there are any, use marine-grade epoxy to fill them and make sure the area is sealed.

This will ensure a strong bond and help protect the integrity of the boat.

Finally, you may want to install additional features to your new transom.

This could include a transom drain, a motor mount, or a transom access hatch.

Depending on what you are looking for, these features can add some convenience and value to your boat.
