Thanks Fred, it looks like the ACU-200 should work.

A quick correction to my email below: the Raymarine ACU-200 has a maximum 
continuous current rating of 15 amps.

Hi, Ken!  As far as the Octopus vs the Simrad drive, the 1012LAM7 has a 
slightly shorter stroke than the Simrad (178mm vs. 200mm).  Depending on the 
geometry of your tiller arm arrangement, it may or may not work without a 
little modification.  As far as the electrical requirements, the Simrad is 
rated at 3.3-5 amps (10 amps peak), the Octopus is rated at 4-6A (19 amps 
peak).  And the Simrad has a peak thrust rating of 350kg and the Octopus has a 
peak rating of 400kg.  They’re very similar in most respects.

Defender has the 1012LAM7 for $1499.99.  Occasionally you can find one for less 
elsewhere online.

As far as the Raymarine goes, here are some answers:

1.  p70 — correct; and yes, you can have more than one in a system
2.  EV-1 heading sensor — correct
3.  ACU-400 — a little bit of a gray area here.  Typically I like to be a bit 
conservative when it comes to autopilot systems.  The max current rating on the 
ACU-200 is 15 amps, and the stated maximum for the Octopus is 19 amps; but I 
think you’d be REALLY hard-pressed to see those kinds of loads typically on a 
boat the size of yours.  At worst, you’d pop the fuse in the ACU and need to 
replace it.  I sold an Octopus/ACU-200 system to Richard Bush on the list, and 
I haven’t heard of any issues at all with his system.  Granted, he’s 
river-sailing, and not going offshore into heavy storms.  But for all coastal 
sailing and most bluewater, the ACU-200 will work fine with the 1012LAM7; I 
really doubt you’re going to go over the peak rating of the ACU-200.   [Let the 
flame wars commence…]
