Replacing the belt
The drive belt is designed to be user serviceable. If there is
insufficient adjustment to cure a slipping clutch, or if the drive belt is
damaged in any way (if it is broken, frayed or stretched), you should
replace the drive belt. You can obtain a replacement belt from any
Raymarine dealer (part number A18083). Fitting instructions are
supplied with the belt.
