May want to start your search here. I have purchased St4000 parts (and sold) here before. Home . The Boaters' Resale Shop of TexasI have a Raymarine ST4000 autopilot and the wheel drive unit when out. Is the Raymarine ST4000MK2 Wheel Drive compatable and will it work with the ST4000??
The black markI and gray markII wheeldrives are interchangeable, electrically. There is a small difference in the diameter that can require you to use an alternate mounting position. Normal is with motor on Starboard lower quarter, some Catalinas with the pedestal mounted engine instrument pod interferes with the gray mk2 motor. Alternate position is with WD motor upper port quarter or sometimes a third position must be created for clearance. I'm using the older black mk1 drive because of this physical fitment problem, and I've got 2 that I've rebuilt.
The motor seemed fine, the belt did fail. I purchased another belt and it never worked properly. Seemed to slip alot. Is there anywhere I can purchase a rebuilt one?What happened to your system? Was it the motor? Is there no signal to the unit? Did the belt fail?
The wheel part is the tool that follows the signals.
I'll check it out. ThanksMay want to start your search here. I have purchased St4000 parts (and sold) here before. Home . The Boaters' Resale Shop of Texas
