Autopilot Tiller Arms

Each Autopilot Tiller Arm is custom machined for a tight fit to your rudder-post.  Please email our Customer Support or give us a call at (508) 995-9711 to order. Prior to ordering, please complete the tiller arm worksheet, which requires detailed information on the attachment method and a rudder-post measurement to an accuracy of 0.001. The worksheet and information on Bronze and Aluminum Autopilot Tiller Arms can be found below. Please read through EB380, our installation worksheet for details on each securement method. 

To order a Tiller Arm, fill out EB373-Tiller Arm Data Sheet, and email the worksheet to info@edsonintl.com. We will review your worksheet and contact you to finalize your order.

IMPORTANT - Edson highly recommends installing an autopilot independent of the primary steering system. This provides for a redundant/backup system in the event of steering gear or cable failure—in effect an “Electronic Emergency Tiller”. Edson’s Autopilot Tiller Arm allows the autopilot to be mounted independently of the primary steering system and should be used to attach an autopilot to the rudder-post.

IN NO CASE SHOULD THE AUTOPILOT BE ATTACHED DIRECTLY TO THE QUADRANT OR RADIAL DRIVE WHEEL!
