[CA] [CA11] EV-200 seems to over-correct

Welcome to the Raymarine Forum dove,

The HC5345 steering ram has a cubic capacity of 8.34 cu. in., and as such would indeed require that an autopilot featuring a Type 1 Hydraulic Pump be installed. It is recommended that the software level within each of the autopilot's components be determined via the corresponding diagnostics feature of MFDs running LightHouse II software. If not operating with the latest software, then the software within any component which is not current should be updated accordingly. Should the autopilot's software have been updated in the past or as a result of having Pilot Factory Reset prior to executing the Dockside Wizard and cruise to determine the vessel's deviation table. Should this not have occurred following the last update to the autopilot's software, then it is recommended that this action be taken. Should the problem persist thereafter, please indicate whether a rudder referenced transducer was installed. Please additionally specify whether the system features a transducer featuring a paddlewheel and if so, whether it has been calibrated, and finally, what what the values for the Speed and SOG data items are when the reported problem is observed (I'm seeking information about the difference in these values).
