[CA] Upgrade Autopilot - CaptDaveHowe - 12-03-17 09:27 PM
The Raymarine package I have on my Mainship Pilot 43 consists of dual E80 displays, with a ST8001 Autopilot. I’m looking to upgrade my system to the Axiom 9 or 12 MFD, with a either an EV-200 or EV-400 autopilot.
Q1: Which autopilot system should I use?
Q2: Can I use the installed drive unit?
Thanks, Dave

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.

Thanks Chuck.
I found the hydraulic drive in the boat, which is made by Sea Star, model BA175-7TM, HC5319. The volume is 13.7 in (226.4 cc).
The marine electronics on board are all 12 V.
Thanks,
David

David,
Should the vessel only have one steering ram and should cubic capacity be 13.7 cu. in. as you have indicated, then you should find that a Type 1 Hydraulic Autopilot Pump has been installed onboard. If so, then this pump, as well as the 12V power distribution system, Raymarine's recently introduced T70407 EV-150 Power Pilot would be recommended to address the needs of those who will be upgrading to an Evolution autopilot from a legacy Raymarine autopilot which utilized a 12V Type 1 Hydraulic Pump.
The rudder reference transducer designed for use with the SmartPilots is also compatible with the Evolution Autopilots

Thank you Chuck.
I did go into the boat underneath the helm and found the Type 1 hydraulic pump. So it looks like we’re good to go.
Thanks again!
Dave
