Attwood SP-4000-ADJ-RB Transom Saver 24 to 36 in - Heavy Duty Support

In this review the Attwood SP-4000-ADJ-RB Transom Saver is evaluated for boaters who trailer outboard-powered craft and want to reduce stress on the transom during transport. The bottom line: it is a straightforward, heavy duty solution that reliably supports the cantilevered engine and prevents transom strain, especially useful for mid-sized outboards. Ease of installation, rugged construction and the adjustable 24 to 36 in length make it a practical choice for owners seeking a durable trailer support rather than a lightweight or decorative brace.

Key Features

• Adjustable Length: The 24 to 36 in adjustability lets owners set the saver to match a wide range of boat and motor combinations for proper support.
• Heavy Duty Head: The robust head with replaceable rubber pads secures the engine and cushions contact to protect the transom and lower unit.
• Multiple Mount Options: Includes choice of mounts for the trailer end so it can attach to either a roller bracket or a trailer mount bracket for flexible installation.
• Rugged Construction: Built with durable materials intended to withstand road vibration and repeated use while trailering.
• Engine Support: Designed to reliably support the cantilevered weight of outboards during transport, reducing stress on transom mounts and bolts.

Who It's For

The Transom Saver suits recreational boat owners who regularly trailer outboard boats, especially those with mid-weight to heavier motors where transom stress is a concern. It is a practical pick for owners of boats with 115 hp class engines and larger where customers reported good compatibility.

Those who should look elsewhere include boaters wanting a lightweight, minimalist tie-down for occasional short moves or operators of very small inflatable tenders that do not require cantilever support. Also verify mount compatibility if your trailer uses an uncommon bracket layout.

Pros & Cons

• Customers report good value for money and easy installation on common outboards.

Cons

• Durability feedback is mixed; some users find it very sturdy while others note typical wear over long service, so occasional inspection is recommended.
• International versions may differ in labeling or instructions, so buyers abroad should check for local variations.
