Sliding Auxiliary Motor Bracket (Stainless) – Standard & Extended Models (up to 15 HP)

This stainless sliding auxiliary bracket comes in two length variants to meet different boat requirements. Both models share the same reliable construction and features; the difference lies in the maximum vertical travel: the standard 02311 model provides about 60.5 cm of movement, while the extended 02311-90 offers up to 90 cm of movement. This allows you to choose the optimal version based on your boat’s transom or platform height.

Construction and Features: The build is marine-grade AISI 316 stainless steel, ensuring strength and corrosion resistance. The slide rails are designed to support the weight and thrust of an engine up to 60 kg, and in the extended model the rails are dimensioned to remain stable even at the lowest position. For sliding action, Teflon bushings/liners are used, minimizing friction and unaffected by saltwater.

Both models have an automatic locking system at multiple positions: as you slide the motor, the mechanism “clicks” into preset stops (typically at intervals along the travel) and can be fixed there. This is useful for fine-tuning the height – for instance, to set the motor at just the right depth in the water under different boat load conditions. When the motor is fully raised, the lock holds it securely at the top.

A safety strap is included with both versions – it keeps the engine snugly against the bracket at all times, but is especially important at the extreme up or down positions to avoid any excess vibration. The strap has a quick-release buckle and can be tightened to fit the shape of your outboard.

The wooden pad (13 x 20 cm) is slightly more compact than on some other models, but more than sufficient for engines up to 15 HP. It’s made of high-quality plywood, laminated/varnished, providing a secure non-slip surface for clamping the motor.

Choosing a Model:

• Choose the standard model (60.5 cm travel) if your boat’s transom is at a relatively normal height above the water (e.g., a 4–5 m fishing boat, a RIB with a low transom, or if mounting the bracket directly on the transom of a rubber dinghy). This model will cover most common scenarios, allowing enough movement to raise the motor when planing on the main engine or to adjust for trolling.
• Choose the extended model (90 cm travel) if your boat has a higher freeboard or you plan to mount the bracket on a raised platform (e.g., on a sailboat’s stern rail or a high transom/platform on a powerboat). The extra ~30 cm of travel provides more flexibility – the motor can reach the water even from a higher mounting point, and when retracted it can lift significantly above it. The extended variant is excellent for cases where a standard 60 cm just isn’t enough.

Usage: Both versions are suitable for boats around 4 to 7 meters, using an auxiliary engine up to 15 HP – whether for trolling, emergency get-home power, or harbor maneuvers. Operation and maintenance are the same as with any sliding bracket: slide the motor to the desired position, ensure it’s locked, and secure it with the strap. While the engine is running, always keep the strap tightened – this extends the life of the bracket and reduces stress from vibrations.

Installation and Maintenance Tips:

• Installation: Both models mount with four bolts to the transom/platform. The extended model (90 cm) exerts slightly more leverage when the motor is lowered, so ensure the mounting surface (transom) is very well reinforced – use an additional backing plate on the inside if needed. The bolt pattern is the same for both models (standard flange), so you can even swap a standard for an extended model later, or vice versa, without drilling new holes.
• Maintenance: As with any stainless bracket, rinsing after salt exposure is important. Particularly with the extended model, take care to flush the entire length of the rails – when the motor is fully raised, the lower part of the rails rarely gets washed by waves, so manual rinsing is needed. Lubricate the locking pins periodically and check the strap for wear (it’s a consumable and can be replaced if needed).
• Safety: Both models are rated for up to 60 kg – do not exceed this limit. For instance, if you have a 20 HP 4-stroke (which is typically ~55-60 kg), that’s at the upper edge – ensure it’s clamped very securely and avoid abrupt shocks. For anything heavier, consider a higher-capacity bracket. Always buckle the strap, and before high-speed running with the auxiliary stowed, double-check the locks are solid – the extended model will hold the motor higher, but it too must be secured against wave impact.
