Welcome to the Raymarine Forum Barry,

Q1. My question is; what do I have to replace?
A1.
1. Compass - yes ... correct, replace EV-1 CCU
2. Control Head - yes ... correct, replace with p70S
3. Pump - I don't know ... it may be possible to retain the hydraulic pump for use with the Evolution autopilot. There is no need to replace the steering the vessel features hydraulic steering. Please indicated whether the vessel features hydraulic steering and if so, then please respond with the model of pump and the cubic capacity of the steering ram which is currently installed onboard.
