I find it all very confusing, but I think if it's an unbalanced helm it will work. But not a balanced helm as side mount Rams don't move equal both ways if I am correct

As said, a standard helm will work but a pro won't. You may also have to run a small remote reservoir off one of the ports on the back, depends if the volume difference of the ram when extended / contracted is greater than the volume of the fluid the helm itself can hold. That's easy though

latham

the reservoir in question is this one:

the latham hydraulic connexion is this one ( 230.pdf file):
http://www.boatmad.com/forum/f5/stee...tml#post223246

to know if some people are happy and others not, here a post on the subject:

Who's using a Seastar helm with side ram steering? [Archive] - Scream And Fly Powerboat and High Performance Powerboating Discussion Forums

for some users the 2.4 seastar 1000psi is Ok for other not, depend the stroke you use, the stroke determine the volume you have to receive in the 2.4 seastar pump if you don't use the additional latham or seastar reservoir.
the system is notbalanced when you use only the pump and the latham cylinder as the piston in the latham cylinder is not at the same surface of pushing on each side.
So you need to determine the oil displacement volume you'll have to know if this volume enter in the seastar pump body, without generate air enter in the oil circuit due to a low level in the seastar pump.

Ask Hypro marine in UK,
you can swap Latham reservoir to seastar reservoir,
SEASTAR SOLUTIONS SeaStar Hydraulic Steering Reservoir with Relief Valve | West Marine
ask the following reference for the reservoir and for the relief valve.
Mfg # HP5860HY
Or
Model # 12785218

By the way, it's a complicated system, and not the cheapest way for steering.
most people use capilano pump as a return line to the pump is installed.
You need to check if the 2.4 seastar pump has a removable plug, where you can adapt the return line. (per latham drawing).
usually there are four 1/4 NPT port on the rear of pump, check if one is avalable for return line.
Hypro marine can confim you that, and if the total installation price doesn't goes to the sky.

per latham infos:

CAPILANO® SYSTEM FLUID is carried in the helm, requiring no air pressure or separate tank. The shaft accepts standard 3/4" taper hubs, and a remote filler kit is suggested for easier bleeding and operation. Only balanced cylinders and twin cylinders can use the 1275V helm. Single unbalanced cylinders have to use the Hynautic® helm and reservoir shown below.

THE HYNAUTIC® HELM AND RESERVOIR are required with self-contained systems that consist of a single unbalanced cylinder as in the case of a sidemount cylinder on a single outboard motor.
