Am looking at a R25 and was wondering if these boats come with mechanical, or hydraulic steering?
 
My 2010 R25 has both hydraulic steering and autopilot. Seems to be fine

Is the rudder controlled by a hydraulic ram or a mechanical push pull cable ?
IE does the R25 have a hydraulic pump to control the steering unit?

The rudder is positioned with an 'crank' arm controlled by a hydraulic piston.
Hydraulic pump - Yes it does have one.

On a small boat, a compact hydraulic pump with integral hydraulic-fluid reservoir located at the steering wheel connects with sturdy nylon hoses below decks and in turn to flexible rubber hoses to a steering ram at the transom, which reliably turns the outboard(s) as one turns the steering wheel.

The pump is attached to the helm, the turning of the helm operates the pump, there is not a motor!

Am I correct Captain's???
 
Here a picture of the Hydraulic steering ram and linkage to the rudder. The Helm is the Pump. If you have an auto-pilot it also has a hydraulic electric pump that over rides the Helm pump when using auto-pilot

Thank you, Sir

I've been fighting with my helm unit since I purchased the vessel. I have notchy steering and hydraulic lag...filled it, purged it, cursed it...best results was the cussin', I think it may be the nature of the beast

You are correct 🙂

For interest, his type of system was (is) also used on larger vessels. In my very early days learning to be a marine engineer I worked on the Blue Funnel ship Priam shortly after delivery. If my memory is right this ship was 11-12,000 DWT. One of the jobs was to check what was called the telemotor system. Very similar to what we have on our Tugs but the wheel operated rams at the bridge that were connected to corresponding rams at the rudder. There was redundancy in the system in case a cylinder failed and we had to charge the system using a hand pump. No pumps meant low pressures and continued availability in case of power failure. I actually thought about that ship this week when servicing our R25SC. I remembered working around the 30,000 SHP diesel and thinking some places were really tight. Nothing, however, compared to changing the impeller on the Tug!! (Though I confess to being 40lbs heavier now ) 😉
 
Thank you all for the information, I'm trying to see how hard and costly it will be to install a cockpit helm station prior to making a offer on a R-25
