[CA] Upgrade Autopilot

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Dave,

Q1: Which autopilot system should I use?
A1. Specification of an autopilot for a vessel having hydraulic steering is dependent upon answers to the following:
- how many steering rams are installed onboard?
- if more than one steering ram has been installed onboard, are the steering rams installed in parallel to one another or in series to one another?
- what is the cubic capacity of the vessel's steering ram(s)?
- is the marine electronics system powered from 12V or from a 24V power distribution system?

Q2: Can I use the installed drive unit?
A2. Quite possibly. However, the answer will be dependent upon the responses provided to my response to Q1.
