Default Raytheon S1 Autopilot Question

Found what seems to be an old NIB Raytheon Autopilot. It is an S1 Corepack, type 1 pump, ST 8002 head, rudder reference and fluxgate compass. Raytheon code for the box E12116 and it is listed for inboard applications.

Unfortunately, I own a boat with twin outboards. The type 1 pump appears to be compatible with my helm, so, rough idea, does anyone have any idea if this unit will work with my boat if I purchase an outboard rudder reference and switch out? Cost of the box is about $600, so, I am trying to figure out if it makes any sense to do this.

Am I just wasting my time?

Check the RRU, you might just need a bracket. If it's a "potted" unit (potted is packed with epoxy to protect the electrical connections), you should be good to go. An "outboard" RRU (the linear one) will self destruct if used with the rotating cylinder Teleflex rams. I know 'cause it happened to me.

So basically, sounds like this package will work with the boat, I will either just have to mess with the rudder reference indicator or buy the linear one. Make sense? Really would like a decent autopilot for the boat I am just to cheap to pull the trigger on a $2,500 unit.

If you have a Teleflex hydraulic steering system, I'd STRONGLY recommend AGAINST buying a linear RRU. The rotating cylindar of the Teleflex system will cause the linear RRU to eat itself up. You need a potted rotating RRU for the Teleflex system. I believe the Raymarine part number is M81105, but I'd call the Raymarine customer service to confirm that part number and that it is to be used in outboard applications.

that is older technology and probably won't work quite as well as the newest units, but seems like a bargain. as mentioned, you can adapt the rotary rfu to work w/outboards. i think someone even posted pictures on this site of a setup.
