Hi Dave
I got a reply from Genco Marine on cost for the octopus unit, the ACU 200 and a 
rudder position sensor. Would be interested if you’re exploring a tiller arm 
alternative. There are some machine shops around here, but I don’t have any 
real good contacts yet.

The reason they gave you a non-answer is they see liability in their future 
when someone forgets the extra switch and can’t retake manual control and runs 
over a boat full of preschoolers on a field trip.
Make SURE you aren’t either driving into the rudder stops and also are not 
using the autopilot drive as a rudder stop. This means you could hit the stops 
but program the autopilot not to. You HAVE to be able to do this.

Joe, great summary of the issues, thanks.
This is consistent with much of the information I've received so far.

  *   The RS drive is electric, and requires 7A - less than most hydraulic 
drives.  Apparently it also offers less resistance when not in use.  The ACU 
100 can supply just enough current (IIRC)
  *   The RS also has an electrically operated clutch (equivalent to the 
solenoid you mention) and requires this capability in the autopilot control 
unit.   The Ray ACU 100 has no provision for this, the ACU-200 does.  As you 
mention, the possibility exists to control the clutch manually with a switch, 
and in any case the RS can be overridden by hauling on the wheel in an 
emergency,.  The ACU-200 was the smallest Ray ACU recommended by octopus, I 
believe this is due to the provision for the clutch..
  *   The RS has an optional rudder position sensor that is gear-driven and 
mounts as a module on the drive motor assembly - so no separate installation 
hassle.   All Ray ACUs support this sensor.
  *   The RS drive's motor is mounted remotely at the end of the supplied 6' 
bowden cable, on a 6"X6" plate, not sure of the height.  Longer cables are 
available.
It might be worth trying this setup with the ACU100 and saving a grand at the 
risk of blowing the output fuse.  When asked about manually switching the 
clutch, the tech at octopus gave me something like a non-answer.

Am going to mock up a drive/cable to ensure that I can make a really clean 
install.   Will also explore local machine shops who might be able to fabricate 
a tiller arm. (if anyone else is interested, please reach out, and if anyone 
knows of a shop who can make one, would appreciate hearing more..)  the edson 
unit seems very spendy for what it is.

I have the ancient predecessor to that autopilot, the old AH-4000. I collect 
parts of them when I find them to have spares and recently was messing around 
with my drive units. One of them was always undoing itself, so I had a bungee 
for the lever to keep it on. The other one was doing the opposite, it would 
slip when loaded up. Full power on the engine was enough to make it slip. 
Apparently slipping is a belt too loose and popping off on its own is a belt 
too tight. I managed to combine the best parts of the slipping one with a 
couple other drives and a new belt and now I have one that neither slips nor 
pops loose :) I think the newer grey ones have a much easier way to adjust the 
belt. If your drive pops the lever loose on its own, try loosening the belt a 
bit.
The EV-100 should be vastly superior to my old AH-4000 course computers. Mine 
will drive a ruler straight line upwind or in calm conditions, but following 
seas can confuse it and it really can't cope with a spinnaker in a lot of wind.

Now for what you are trying to do, there are a few layers to the problem. One 
is the total current the drive transistors can control. There is no way the old 
4000 could ever power a hydraulic drive. Maybe the EV-100 can sink that much 
current?? The next issue is the solenoid valve. Hydraulic units lock the rudder 
in place when the autopilot is on by closing a bypass valve and opening the 
valve allows you to steer by hand again. You would need to rig something to 
operate that valve. You could just have a switch on it you activate yourself, 
but this has an obvious pitfall if anyone but you is running the boat. The last 
issue is the algorithm the autopilot uses to steer the boat. You really would 
want a rudder reference and even then I can't say for sure how well the 
autopilot would adapt to a much different level of response than it expects 
from a wimpy wheel drive. You need the autopilot to NOT try ramming the rudder 
into the stops with full force. The wheel pilot can do that and not break 
anything, hydraulics not so much.

Hello Dave
I am following with interest as you work through this, I also have the 33/2 and 
the EV100 wheel, which I am NOT happy with. It doesn’t steer in less than ideal 
conditions and has taken to skipping recently, at very least I need to tear the 
drive apart and see what’s going on. Last winter at the TO boat show the 
Ray-rep suggested all I needed was to upgrade the software, which I can’t seem 
to do through my smart phone and chart plotter for some reason.
Thanks for keeping us updated

Re: Stus-List Raymarine to octopus drive upgrade - UPDATE

[Dave via CnC-List]

It’s a fair question as the wheelpilot works fine in gentle conditions.
I generally sail singlehanded and sometimes in rough or breezy conditions it 
unlatches or partially unlatches itself.  This has been quite a surprise a few 
times, not always a safe one.Have read that many owners rig a bungee cord 
to hold the latch closed.  
I realize it can be adjusted though the plastic bits and means of adjustment 
seem really Marginal to me.   maybe I haven’t spent enough time playing with it.
I don’t like the motor noise.  (Lol)
I’m hoping the drive will be faster, which would help a bit off the wind in 
rougher conditions, which is also when it unlatches.  Again to be fair I 
sometimes carry quite a bit of sail, part of the fun for me.
I guess in the end it doesn’t seem as bulletproof or effective  as the other 
work or upgrades I’ve done, (which, to your point, come at a price) and I don’t 
quite trust it.  
It it fails and I’m solo that would be a real nuisance for me, and I’m 
progressing through longer passages in more challenging conditions as I learn.
I welcome any comments or suggestions.
Dave

Dave,

Interested why you feel the current unit needs to be replaced. We put the ray 
system you have on Perception our 33-ll 3 years ago when we upgraded our 
electronics so far it’s performed as well as the Navico wheel pilot it 
replaced, and as Dennis has said they work well! With our short season I could 
not justify the expense and effort to put in the octopus unit, which I really 
wanted to use.

Used the saved funds towards the rest of the electronics upgrade.

With our hydraulic ram and the ACU 100, the ram could, under severe weather, 
draw more power than recommended for the ACU 100, but in emailing back & forth 
with Fred Street, it came down to the idea that rarely, if ever would most 
people come across such circumstances, especially if they are coastal cruisers.

Answering my own question here - for the record.   It would appear that the 
acu-100 is limited in the current it can deliver to a drive, and is therefore 
only recommended for the smallest types.  I expect though, that this could be 
overcome by using the
 acu to operate relays of  adequate ampacity.

I am planning on doing the same, though I am planning on going with the 
Raymarine drive.  As I understand it the AC 100 is not compatible with the 
drive and I’ll have to go with the AC 100.  Raymarine offered a modest discount 
with the trade in.  As I
 remebmber it was $400 plus the old AC100.


No idea about the Octopus drive.

Looking to upgrade my Raymarine EV100/p70/acu100/ wheel drive to a below-deck 
linear actuator.    Octopus has an electric linear drive that appears to be a 
good choice for the tight confines of a 33-2

http://octopusdrives.com/products/type-rs-sailboat-drives/

Looks like I?d need the drive and a tiller arm. 

Any suggestions as to a source for the tiller arm?

Wondering if the acu-100 is compatible with the octopus type RS?

Has anyone done this conversion?   Any advice would be greatly appreciated.

Thanks, Dave

at also have a clutch connection, not supported by the acu100 or 150 (which

Answering my own question here - for the record.   It would appear that the 
acu-100 is limited in the current it can deliver to a drive, and is therefore 
only recommended for the smallest types.  I expect though, that this could be 
overcome by using the acu to operate relays of  adequate ampacity.
See below.

I am planning on doing the same, though I am planning on going with the 
Raymarine drive.  As I understand it the AC 100 is not compatible with the 
drive and I’ll have to go with the AC 100.  Raymarine offered a modest discount 
with the trade in.  As I remebmber it was $400 plus the old AC100.

No idea about the Octopus drive.

Re: Stus-List Raymarine to octopus drive upgrade

[Bruce Whitmore via CnC-List]

Hello all,
While I might get roundly criticized for this, we had an old hydraulic 
autopilot that had died and needed to be replaced.  I think it might have been 
a Navtech.  It was connected to an Octopus hydraulic ram, and it had a small 
control box mounted on the ram itself.  I was told by Octopus that the ram 
would not be compatible with new autopilots, and was specific to the old 
system, so I was looking at having to replace the ram as well as the brains of 
the unit.  

I went with the Raymarine EV-100.  

As I started to look at the ram, I removed the little control box and found 
that the wires and circuit board eventually resulted in 2 pins going into the 
ram.  So, I tried simply created a pin connector and ran the resulting wires 
back to the control box on the EV-100.  Works perfectly.
So, I did not have to replace the ram.
If you don't have a ram in place now, this won't help but...
