Jay,

Will forward the manual today.


Regarding the EV100: the key is mounting the course computer far from magnetic disturbances.

I originally mounted in the wet locker behind the head and could not get past excessive deviation errors.

The EV100 replaced the original Autohelm unit.

Finally relocated in the v-berth locker starboard side and it has worked well since then.

Pls copy all of us old PSC 31 owners a pdf of your owner's
manual. My old paper copy is getting worn.

Regarding a good heading source for any of the autopilots
substituting a satellite compass source into the network
has worked well for me and maybe for you. I have installed
a full NEMA 2000 network system and since mine was from B&G
(Navico) I used a ZG100 to provide a stable plot for my
radar overlays to the chart plot. Provides GPS, course
(True or Mag), and heal angle sentences to the network.
Heading is now no longer derived from a stabilized magnet
source.

Now I am even able to swing my helm compass without using
visual range lines as called out in the Ritchie Compass
users manual.

I use my ZG100 heading source as primary on my NEMA 2000
network and my old Raymarine Smart pilot picks it up rather
than the old hardwired fluxgate compass that is part of the
kit It also picks up my other sensors inputs from any
data sources on the 2000 network. I believe the EV 100 has
a more advanced fluxgate compass, but still suffers from
onboard deviation sources. Therefore, you might check to
see if your autopilot can use any heading sentence on their
NEMA 2000 network and go with a satellite compass.

This thread parallels my experience.
