I started on my quest to install a Raymarine SPX10 core pack with a suitable drive for the boat. Having visited the boat show this looked fairly simple; just buy a complete pack including a linear drive and the jobs a good one.
If only life were that simple; it looked easy as the Oceanis 31 is fitted with a  tiller arm pre fitted with a tiller pin to attach the drive to. However on measuring, not only was the arm longer than I expected but the tiller pin was 15mm in diameter. The Raymarine linear drive rod end bearing is 12mm in common with most hydraulic Rams. The length of the tiller arm also meant I would need a 12” stoke on the drive.
I checked with the Beneteau agent and it turned out that Beneteau fit a hydraulic ram that is a type 2 drive which would mean buying a type 2 core pack. This was not on, both on the grounds of cost and overkill on a small yacht.  I looked at getting a rod end made, as you cannot easily buy a 15mm rod end, but it was all getting a bit complicated and would have meant buying the drive and then looking at modifying the rod end, I wasn’t prepared to do this in case I ended up with a “pig’s ear” of an installation.
I happened to come across an Octopus RS drive from a Canadian company that looked like it might fit the bill. I made contact with the European office and explained what I was looking for and Tim Bell in Spain sent photographs of the drive attachment and we concluded the standard fitting would not meet my needs. Tim at this point brought in Dave Shannon from Octopus Products in Canada who designed a custom fitting for the Beneteau tiller pin. From start of design to having it in my hand was only 3 weeks. It fitted perfectly.
