Spare parts for autopilot

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Jeffrey,

First, I want to wish you well in this venture. With respect to spares, the EV-1 Sensor Core, ACU-400, p70/p70S/p70R/p70RS, and mechanical linear drives are not designed to be serviced in the field, and as such, repair kits and the corresponding procedures to troubleshoot and repair these products are not available. These products are designed to be service by Raymarine's Product Repair Centers and a limited number of servicing dealers. If seeking full redundancy, then one would carry each of the items included with the EV-400. That said, short of a lightning strike taking out the electronics, the Evolution autopilot components which would be most subject to wear/failurd would be the following:
- M81105 Rotary Rudder Reference Transducer
- E70100 ACU400 (includes M81105)
- Type 2 long linear drive (M81132 (12VDC), M81134 (24VDC))
