Plastic Transom Mount Pad for Outboard Engine

EVAL’s plastic transom pads are designed to reinforce and protect the area where your outboard motor clamps onto the transom. They are made from reinforced polypropylene that is highly resistant to UV rays, meaning they won’t crack or degrade even after prolonged sun exposure. The top surface features a new anti-slip pattern which provides better grip and a safer, more secure seating of the engine on the boat. By using these pads, the boat’s transom is protected from direct engine contact, as the pad distributes pressure and vibrations and reduces the risk of damage.
Using the pad is extremely simple – just position it between the outboard’s clamp screws (or bracket) and the transom surface before tightening the motor. When you tighten down, the plastic plate takes the stress and spreads it out over its area instead of it being concentrated right under the bolts. This is especially useful on smaller boats or inflatables with thinner transoms, where focused pressure could cause deformation. Employing the pad protects the transom’s finish as well from scratches that would occur with metal-on-fiberglass/wood contact.
The pads come in multiple sizes and colors. The larger variant (e.g. 270×100 mm, ~5–7 mm thick) and the smaller one (e.g. 227×87 mm) cover different areas depending on your engine’s bracket size. The typical colors are white and black – you can choose the white pad for a light-colored transom or the black pad to match a dark/black engine, blending in aesthetically. The material (polypropylene) is lightweight, so it adds virtually no weight or stress to your boat. At the same time, it’s tough – resistant to impacts, saltwater, and temperature changes.

• Typical use cases: Ideal for inflatable boats and RIBs where the aluminum/plywood transom can be marred by engine clamps; for small fishing boats whose outboards are frequently removed for transport or service – the pad preserves the surface; also used as a spare part – for example, on adjustable outboard brackets or anywhere a plastic pad is desired to spread loads.
• Recommended boats: Suitable for any boat with an outboard up to about 30–40 HP – especially useful on small fishing boats, yacht tenders, inflatables. For higher horsepower outboards (e.g. 50+ HP), the transoms are usually more robust, but the pad can still serve as extra protection for the finish.
• Installation & maintenance tips: Ensure surfaces are clean – free of sand or grit – before placing the pad to avoid scratching the transom. You can use a bit of tape to hold the pad in position while tightening the motor to prevent it from slipping out. If you want a permanent install, use marine adhesive or small screws in the pad’s corners (some pads come with screw holes). Inspect the pad during annual maintenance – the material doesn’t wear out much, but just verify there are no cracks or UV damage. If dirty, wash with water and mild soap (avoid solvents that could harm the plastic).
