Check the belt. My autopilot acted like that when the belt was shot.

Subject: Stus-List Raymarine Autopilot Question 

Listers,

Yesterday, on a dinner trip to Oyster Bay, our autopilot stated to malfunction 
after about an hour or so.

It would be holding a course, then start veering to port, then to starboard, 
then much more to port, then much more to starboard . . and so on. Eventually, 
it would get so far off (over 90 degrees), a the autopilot would disengage. I 
shut it down and tried to restart it by cutting power to it for about a minute, 
then it would happen again after a minute or two. 

I tries setting the p70 to “performance” to keep the boat more tightly on 
course, but that had no effect. The display kept showing how far off we were 
(so I know the EV sensor core was working), but it wasn’t correcting course 
properly. 

I ended up turning it off completely, in fears of getting a DUI inquiry from 
all the S-turns. 

Any ideas? To clarify, I have a ACU-200 and a ST4000+ wheel pilot. And, up 
until yesterday, it was working flawlessly. 


All the best,

Edd
