  • Remove the old transom
  • This may be accomplished by removing the screws that hold it in place, or by cutting it out with a power saw
  • Cut a new piece of plywood to size, using the old transom as a template
  • Drill holes for the screws that will attach the new transom to the hull of the boat
  • Coat both sides of the plywood with fiberglass resin, using a brush or roller
  • Lay two layers of fiberglass cloth over the wet resin, and coat with more resin
  • 6Attach the new transom to the hull with screws, and allow it to cure overnight before use

Reinforcing The Bertram Transom With New Fiberglass

Transom Strengthening Plate

If you have a boat, then you know that the transom is one of the most important parts. It’s the back wall of the hull and it supports the engine. So, it’s essential that it be strong enough to handle whatever you throw at it.

That’s where a transom strengthening plate comes in. A transom strengthening plate is a metal plate that is installed over the transom. It reinforces the transom and makes it stronger.

This is especially important if you have an outboard motor, as they can put a lot of stress on the transom. Installing a transom strengthening plate is not difficult, but it is something that should be done by a professional. They will know how to properly install it and make sure that it is secure.

Once it’s installed, you’ll be able to rest easy knowing that yourtransom is much stronger and less likely to fail.

Transom Reinforcement Bracket

Transom reinforcement bracket is an important part of the hull of a ship. It helps to prevent the transom from being crushed by the weight of the superstructure above it. The bracket is usually made of steel or iron and is bolted to the side of the hull.

How to Strengthen Transom for Bigger Motor

If you have a big motor, you’re going to need a strong transom. Here are some tips on how to make sure your transom can handle the weight and power of your engine: 1. Inspect the transom for cracks or damage.

If there are any weak spots, reinforce them with fiberglass or another sturdy material. 2. Make sure the motor is properly mounted. All bolts should be tight and secure, and the motor should be level with the boat’s hull.

3. Check the alignment of the propeller shaft. It should be perpendicular to the bottom of the boat, not angled up or down. 4. Have a professional check out your boat if you’re unsure about anything related to the strength of your transom.

They can give you specific advice on what needs to be done to strengthen it.

1. Remove the old transom. This is usually held in place with bolts or screws. You’ll need to remove these before proceeding.

2. Cut a new piece of plywood to size and shape. It’s important that this new piece is exactly the same size and shape as the old one, so take your time measuring and cutting accurately. 3. Affix the new plywood piece to the hull of the boat with marine-grade adhesive or epoxy resin.

Be sure to apply a generous amount so that it will hold securely. 4 . Drill holes through the new plywood and into the hull for bolting or screwing in place .

Again, be precise with your drilling so that everything lines up correctly . 5 . Install bolts or screws through the holes and into the hull , then tightened them down securely .

Make sure everything is tight before moving on .

How Do I Make My Transom Stronger?

There are a few things you can do to make your transom stronger. One is to add some reinforcement ribs to the inside of the transom. This will help to distribute the weight of the engine and any other loads more evenly, and will also stiffen up the transom so that it is less likely to flex under load.

Another option is to add a layer of fiberglass matting to the outside of the transom. This will provide additional strength and rigidity, and will also help to protect the wood from moisture damage. Finally, you can also use marine epoxy or polyurethane adhesives to bond the layers of wood together, which will further increase the strength and durability of the transom.

How Do You Reenforce a Fiberglass Boat?

If you have a fiberglass boat, you may be wondering how to best reinforce it. There are a few different ways that you can do this, depending on your needs and preferences. One option is to use marine epoxy.

This is a strong adhesive that will bond well with fiberglass and help to reinforce any weak areas. Another option is to use Fiberglass Repair Tape. This tape is specifically designed for reinforcing boats and can be applied easily to any area that needs reinforcement.

Whichever method you choose, make sure that you follow the manufacturer’s instructions carefully in order to get the best results.

How Do You Fix a Transom on a Fiberglass Boat?

If you have a fiberglass boat, chances are you will eventually need to fix a transom. Transoms are the flat surfaces at the back of the boat where the engine is mounted. They can be damaged by hitting objects in the water or by age and wear and tear.

When this happens, it is important to fix the problem as soon as possible to avoid further damage to your boat. There are several ways to fix a damaged transom, depending on the severity of the damage. If there are only minor cracks or scratches, you can simply sand them down and repaint or gelcoat the area.

If the damage is more severe, you may need to replace part or all of the transom. This is a more difficult repair that should be done by a professional if possible. If you do need to replace part of your transom, you will first need to remove any old gelcoat or paint from the area.

This can be done with a sander or chemical stripper. Once the area is clean, you can cut out the damaged section using a saw or router. The new piece should then be glued or welded into place and finished off with gelcoat or paint.

Transom repairs can be tricky, so it is always best to consult with a professional before attempting any repairs yourself. With proper care and maintenance, your fiberglass boat will last for many years to come!

How Do You Fix a Soft Transom?

If your boat’s transom is soft, spongy, or otherwise in need of repair, you’re not alone. Many boat owners have faced this problem at one time or another. But the good news is that a soft transom can be fixed relatively easily – as long as you catch it early and don’t let the problem get too out of hand.

Here’s a step-by-step guide to fixing a soft transom: 1. Inspect the Transom for Damage The first step is to inspect the transom for any damage.

If there are any cracks or holes, these will need to be repaired before proceeding with the rest of the process. Depending on the severity of the damage, this may require professional help. 2. Remove All Soft Wood from the Transom

Once any damage has been repaired, all of the soft wood from the transom must be removed. This includes any rotted or spongy wood – even if it doesn’t appear to be damaged. The best way to remove soft wood is with a power drill and large bit (at least 1/2″).

Simply drill through all of the affected areas until only solid wood remains. Be sure to vacuum up any debris created by drilling so that it doesn’t clog up your work area later on. 3 .

Fill in Any Holes or Cracks with Marine Epoxy Putty If there are any holes or cracks remaining after removing all of the soft wood, these should be filled in with marine epoxy putty . This putty can be purchased at most boating supply stores and will provide a watertight seal once cured .

Simply knead together equal parts of each component (A & B) until they are fully mixed , then apply to desired area and smooth over with a wet finger . 4 Let Putty Cure Completely Before Proceeding It’s important to let the putty cure completely before proceeding with anything else . Depending on temperature and humidity , this could take anywhere from 24 hours to a few days . Once cured , however , the putty will be rock-hard and ready for further steps . 5 Cut Fiberglass Cloth Into Strips Next , cut fiberglass cloth into strips that are slightly wider than needed to cover all drilled holes and voids .


If you have a fiberglass boat, you may want to reinforce the transom. This can be done by using a piece of plywood that is the same size as the transom. Cut the plywood so that it fits snugly against the hull and screw it into place.

You can also use epoxy to secure the plywood in place.
