Catalina 30 TRBS #2889 "Northern Light"

Autopilot Drive Belt

The rest of the modifications.

The Raymarine ST4000+ drive belt is no longer sold by Raymarine. It may still be available elsewhere, and for a much lower cost than Raymarine's original price.

Go to , which now apparently is under Megadyne , part number "9.5AT5-750". It appears to be the same underlying brand that Raymarine had carried.
I don't believe it's listed on their website.
