Whether mechanical or hydraulic, the drive is powered by a reversing electrical
motor in most small boat drives. When the size increases, a single continuously
running electro/hydraulic pump is used, and the hydraulic fluid flow is
reversed using solenoid activated valves. Either way, any of the major
manufacturers can supply a control head to power the steering gear.

That's the drive I have on the Enterprise. It's my Robertson unit that won't
run it anymore.
So any control unit could be attached to this?
All the best,
