Know Your Board
The boat transom board can be a bit tricky to figure out—especially if you never consider it until it’s time to repair it. But try to understand what’s going on. Do you have dry rot? Is the wood simply getting old? Do you have other issues that have caused the wood to deteriorate over time? Think of it as diagnosing a problem.
Use A Git-Rot Kit For Dry Rot
Dry rot is one of the frequent problems for anyone repairing their aluminum boat’s wooden transom, which is why it’s a good idea to seek out a Git-Rot Kit for repair. This kit utilizes a two-part liquid epoxy that can penetrate the rot and use the natural fibers of the wood to get deeper into the wood than you might imagine.
Equip Yourself With The Right Materials
Effective boat transom repair means you’ll have to use the right materials along the way—otherwise, you’ll just frustrate yourself and wonder why it can’t be easier.
Clean The Area First
One of the most overlooked parts of effective aluminum boat transom repair is failing to clean out the area first. Cleaning out the area will give you free reign to move around and handle everything that you need to handle. It will also help ensure that you do minimal damage to the rest of the boat as things move around.
Remember, Maintenance Matters
The old saying that an ounce of prevention is worth a pound of cure bears out when it comes to your transom and the rest of your boat. Keep it clean and well-maintained if you want your boat to be as “healthy” as possible.

What is a transom on a boat?
Transoms are major structural parts of fiberglass powerboats, especially outboards. Transoms not only support the weight of the motor, they maintain the shape of the boat, they are a mounting point for holdowns, towing eyes and other accessories. And, they must be able to let water out of the hull, without letting it back in.
How thick is a transom?
In other words, use four layers of 3/8″ or 6 layers of ¼” plywood to build up a 1½”-thick transom instead of three layers of ½”. Be sure to fill any voids in the plywood edges with thickened epoxy after the panels are cut into shape. Make a template of the transom and use it to layout the plywood layers.
What causes a transom to rot?
Moisture penetrates the plywood core, leading to delamination and eventual rot. Moisture can also penetrate the transom skin at hardware fasteners, around drain holes and I/O cutouts. These factors have a cumulative effect on structural failure. When the transom loses its stiffness, so does the outboard motor.
How to laminate fiberglass skin?
If your fiberglass skin is unusable, plan to laminate a new fiberglass skin over the core with multiple layers of fiberglass and epoxy. Apply them one layer at a time until the same skin thickness is achieved. Subsequent layers can be applied immediately or while the previous layer is still tacky. If the epoxy is allowed to cure beyond being tacky, allow it to cure overnight, then wash the surface with water and sand the surface to prepare it for more layers. Laminate the new skin so it extends to the edge of the 12:1 bevel that was machined earlier on the outer edges of the transom. Install the biggest patch first with each layer being progressively smaller to fill the 12:1 bevel. For additional information on laminating a large new fiberglass skin see Section 4.3 of Fiberglass Boat Repair & Maintenance (free download).
How many times does a bevel back from the corner of a fiberglass cut line?
The distance of the cut line (and the bevel) back from the corner is 12 times the fiberglass thickness. A 12-to-1 bevel allows room for multiple layers of fiberglass fabric and epoxy across the cut line to restore strength to the fiberglass skin.
What determines the bevel length of a fiberglass transom?
The fiberglass thickness determines the bevel length which is also the distance from the corner to the location of the cuts for removing the fiberglass skin. As mentioned, the cut line will be located to allow the outer edge of the bevel to end before the corner of the transom.
How to prevent dimpling in fiberglass?
This prevents dimpling in the fiberglass skin which would require considerable filling and fairing later.
