711C running DC motor/pump at variable speed

We have a 43 foot sailboat with cable steering. A Kobelt 7040 B12 hydraulic ram drives the rudder when the autopilot is engaged. The existing motor and hydraulic pump from the prior autopilot is a 1/4 hp 12vdc reversible motor v-belted to a pump. It operated well at variable speeds depending on required course correction. The HOH time is 7.5 seconds (at full output when the "dodge" button was pushed). Maximum motor current draw is about 22 amps.
My question is whether the 711C can operate this motor and pump system on a variable speed basis depending on course correction required?

The Furuno pilot uses Pulse width Modulation to control the rudder speed in any reversing pump installation. It should work for you. The Navpilot Processor has an amazing amount of current drive with a 50 amp surge and 25 amps continuous drive current. 12VDC Surge Power - (12VDC)(50Amp) = 600 watt surge power (about 3/4 HP) 12VDC Cont. Running Power - (12VDC)(25Amp) = 300 Watts Running Power (about 1/2 HP)
 
Thanks for that prompt, positive response. Furuno does not appear to have a hand-held remote available for the 711C. Such a remote is important for use in the cockpit on a sailboat; no display is needed, but buttons for one and ten degree course changes, standby and auto, and dodge are extremely useful. Is Furuno planning for one? Are there any generic or other brands of remotes that might be compatible with 711C?

Thanks for the lead on the remote. Looks as though it will function for dodging, however, we need also to be able to tweak the course in 1 and 10 degree increments. Also for a sailboat, a 90 degree "tack" button is handy when sailing short handed. Guess I'd better move this item to the "desired new products" section.
