Raymarine Pushrod Extension, For Tiller Pilots, Black Machined Aluminum

Overview

The Raymarine Pushrod Extension is a threaded extension piece for Raymarine tiller autopilot pushrods, used when the standard drive arm needs extra reach between the cockpit mounting point and the tiller. It is a practical fit part for tiller-steered sailboats where the boat layout, beam, coaming position, or tiller geometry places the pilot slightly short of the correct working position.

Each extension screws into the end of the standard pushrod and is supplied in a specific added length. The available sizes in this range are 1 in, 3 in, 4 in, 5 in, and 6 in, with corresponding metric lengths of 25 mm, 76 mm, 102 mm, 127 mm, and 153 mm. The extensions are made from black machined aluminum, keeping the part rigid without adding unnecessary bulk at the tiller pilot connection.

This is a small component, but it matters during autopilot setup. Correct pushrod length helps the tiller pilot sit at the right angle and stroke position, which is important for smooth steering response during coastal cruising, short-handed sailing, and dock-to-dock passages where the tiller pilot handles routine course holding.

Key features

• Extends the reach of Raymarine tiller autopilot drive pushrods when the standard arm is too short for the boat layout.
• Threaded installation screws into the end of the standard pushrod, making length adjustment straightforward during fitting.
• Available in five added lengths: 1 in, 3 in, 4 in, 5 in, and 6 in.
• Black machined aluminum construction gives the extension a rigid, clean finish for cockpit-mounted autopilot hardware.
• Useful for installations affected by wider beam, coaming position, tiller shape, or mounting socket location.
• Can be used with Raymarine tiller pilot drive systems where a pushrod extension is required to achieve the correct geometry.

Variants

This Raymarine pushrod extension range is offered in multiple length configurations so the installer can match the tiller pilot reach to the vessel layout.

The changing attribute across these variants is the added pushrod length. The threaded pushrod extension format and black machined aluminum construction remain consistent across the listed sizes.

• D003: Length 1 in, approximately 25 mm. This size adds a small correction where the standard pushrod is close to the right position but needs a little more reach.
• D005: Length 3 in, approximately 76 mm. This size suits installations that need a moderate increase without moving the cockpit mounting point.
• D006: Length 4 in, approximately 102 mm. This length gives more reach for tiller pilot setups where the socket or bracket position sits farther from the tiller.
• D007: Length 5 in, approximately 127 mm. This option is useful when cockpit geometry requires a longer pushrod span for proper alignment.
• D008: Length 6 in, approximately 153 mm. This is the longest listed option in this set and adds the most reach for wider or more offset tiller pilot installations.

Installation and fit

Before fitting, check the tiller pilot installation measurements for the drive model and vessel layout. The extension should help the pushrod reach the tiller connection without forcing the pilot body out of its normal operating angle or placing the drive near the end of its travel when the rudder is centered.

On board, the main goal is clean alignment. The pilot should connect without side loading, binding, or pulling the tiller hardware out of line. When more reach is needed, selecting the closest extension length helps maintain a tidy installation and avoids unnecessary leverage at the pushrod connection.

Use cases on board

This part is a good match for sailors setting up or correcting a Raymarine tiller pilot installation on a tiller-steered sailboat. It is especially relevant after changing cockpit hardware, relocating a mounting socket, replacing a tiller, or fitting an autopilot to a hull where the standard pushrod length does not quite land in the correct position.
