Fixed Auxiliary Outboard Bracket – Stainless with PVC Pad (up to 15 HP / 40 kg)

This fixed transom bracket is designed to provide a stable and robust mount for a secondary outboard engine (also known as a “kicker” or auxiliary motor) on your boat. The construction combines polished stainless steel for the side support brackets and an extremely durable PVC board as the engine mounting plate. The result is a reliable bracket that resists corrosion and weathering, while also looking professional and protecting your boat’s transom.

One of the key advantages of this model is its low-profile, extended-offset design (~140 mm setback). This means the auxiliary motor will be positioned slightly aft and lower relative to the boat’s transom, improving the immersion of the outboard’s lower unit. On boats with higher freeboards or those with swim platforms, this feature ensures the propeller of the auxiliary engine stays sufficiently submerged for effective operation, without the need for a complex adjustable bracket.

The PVC mounting board (approximately 175 x 178 mm in size) is “highly-resistant” – engineered to withstand engine clamp pressure and vibrations during operation. Unlike wood, the PVC material won’t absorb water, rot, or crack, which translates to a longer lifespan and minimal maintenance. The plate is thick and reinforced enough to hold an engine up to 40 kg securely while distributing the clamping force evenly.

The polished stainless steel hardware not only gives a sleek, professional appearance but also provides exceptional strength. AISI 316 stainless steel is highly resistant to saltwater corrosion, ensuring the bracket maintains its structural integrity even after years of use. The fixed one-piece design with no moving parts virtually eliminates maintenance needs – once installed, the bracket is always ready for use with no hinges or springs to wear out or service.

Use Cases and Recommendations:

• This bracket is ideal for boats with a strong transom (fiberglass, aluminum, or wooden stern) that want to add an auxiliary outboard up to 15 HP. It’s commonly used on the swim platforms of yachts and sailboats where a small outboard is needed for harbor maneuvering or to power a dinghy/tender.
• Application on Swim Platforms: The bracket can be mounted on a horizontal or vertical surface of the boat’s stern or swim platform. The 140 mm offset/drop is especially useful for sailing yachts with high freeboards – the motor can sit lower behind the transom, which makes it easier to get the prop in the water. This ensures the propeller remains submerged even in choppy conditions, providing reliable thrust when you need it.
• Engine Selection Tip: The maximum recommended load is 40 kg – typically corresponding to a 15 HP two-stroke or about a 9.9–15 HP four-stroke engine. If your auxiliary outboard is heavier (for example, a 15 HP 4-stroke might be ~45-50 kg), be mindful not to exceed the bracket’s limit. For heavier or more powerful kickers, a beefier spring-assisted bracket might be necessary.
• Safety and Maintenance: After installation, double-check all mounting bolts (stainless hardware is recommended) – they should be tightened securely, preferably with large washers or backing plates on the inside of the transom to distribute the load. When running the engine, periodically inspect the bracket – the fixed design won’t shift on its own, but it’s good practice to re-tighten the through-bolts to the boat occasionally. Since there are no moving parts, the bracket itself requires no special maintenance aside from rinsing off salt and checking the bolts for any corrosion.
