Raymarine 4" Tiller Bracket f/Tiller Pilots

The Raymarine 4" Tiller Bracket for Tiller Pilots (part number D159) is a precision mounting accessory engineered to solve a fundamental rigging problem on modern boats. When a tiller pilot's fixed end sits higher or lower than the boat's tiller, this bracket provides the horizontal offset necessary for proper pilot alignment and smooth operation, eliminating binding and uneven steering pressure that can wear out autopilot systems prematurely.

The 4-inch mounting span allows flexible positioning to match varied helm geometries across different hull designs and tiller configurations. Compact at 7 x 1 x 8 inches and weighing just 1 pound, the bracket integrates seamlessly into existing tiller pilot installations without adding bulk or weight to the steering mechanism. The design accommodates the standard Raymarine tiller pilot interface, ensuring compatibility with the brand's full autopilot ecosystem. Proper bracket selection is critical—undersized or oversized offsets create leverage problems that compromise pilot responsiveness and longevity.

This bracket addresses a practical need for cruising sailboats, fishing vessels, and small to mid-size powerboats where tiller pilots remain the preferred autopilot choice due to simplicity and reliability. Weekend anglers and serious offshore fishermen alike rely on properly mounted tiller pilots for fatigue-free long-distance operation. Boatbuilders and retrofit installers depend on correct offset brackets to avoid steering anomalies that typically emerge weeks or months after installation. The Raymarine D159 bracket is the manufacturer-specified solution for 4-inch offset applications, ensuring alignment with Raymarine's engineering specifications and system performance guarantees.
