PSC has all kinds of hydraulic steering components, mostly for off road, but the steering valves are a great price.

So tell me what cc" unit should you need for a single system and how do you determine that?..................................Rjr........ .......................

do not want tostep on anybodys thread,or sound dumb.but what all is needed for full hyd steering.i have factory hyd streeing with a cable helm.what do i need to make it fullhyd steering?

There is a table in the IMCO catalog that shows helm size / ram stroke, in relation to "lock-to-lock" of your steering.

I had a single ram system that normally uses the 95cc helm, but I used the 120cc with the thought of adding another ram. I never did add the ram, but the steering worked great.

Sounds like you have what is known as an add-on system. Before I converted to a full system, I still had some play in the steering. Once I added the helm, it made a big difference in the precision of the steering.

Just received my parts. Basically you are going to need a helm, steering post, filter, and a bunch of fittings and hydraulic hose. Some say you need a additional tank for fluid capacity and others say its not needed. Imco has an add on kit to complete your current set up to full Hydraulic and CP Performance has a kit made by Mayfair Marine. After a bit of researce I chose the Mayfair kit, it was about $500cheeper and came with the additional tank, and appeared to be a more complete set up IMO, I will see shortly.

I wish I would have got your response sooner I already researched, purchased last week, and got my stuff today.

keep us posted....I am needing to do this now...so with dual rams a 120 pump should do the trick ? thanks

I need to add a completed external system. I have just the cable set up. What would something like that cost and is this something I can do myself? Im mechanicaly inclined and was wounding if this stuff in difficult to do as I would like to save some money by doing it myself. Do these system come with step by step instructions if bought complete? Thanks for the help
