Evolution Autopilot unable to hold course in waves

[Chuck - Raymarine - Moderator]

Willy,

While there is not a quality test which may be provided, a gross check of the EV-1's sensors may be accomplished by interfacing a NMEA 2000 analyzer (ex. Actisense NGT-1 w/NMEA Reader software) to the SeaTalkng backbone to monitor pitch, roll, and yaw data within NMEA 2000 PGN 127257 as the EV-1 Sensor Core's is subjected to motion (it may be helpful to remove the EV-1 from its mount to do so). With respect to comparing another vessel's performance, care should be exercised. When operating in Track mode, it is not the vessel's heading which will be constrained, but rather the corridor width. Raymarine has not specified performance values for heading when operating in Auto mode, but it should be expected that in heavy following seas, the autopilot will not steer as tight a course as it would under other less strenuous conditions. Should you believe that there may be an issue with your EV-1 Sensor Core, then it would be recommended that it be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
