Good autopilot belt
Item as advertised. Install into Raymarine ST4000 was straightforward. Belt worked first try with no adjustment. We’ll see how long it lasts!

Great customer service
After inquiring after the right part for our autopilot per email, defender replied quickly and kindly. We felt confident enough to order this belt and it is a perfect fit. We are very grateful to defender and their staff.

New belt is just my size !
Perfect fit and replacement for 20 year old autopilot. I was afraid it would not be available. Simple to install and instructions available as PDF prior to purchase and in print with product ! So you know what you are getting yourself into. Hey also, if you are reading this far ... by peeking in the 2 holes in the back of the autopilot housing you can check on the condition of the belt.
