kicker wireless remote control question.

[rolmops]

Here goes.
I have a tailfin (powertran) remote control wireless steering setup and a powerpro 3 wireless speed control both for the same kicker. I need 2 remote control fobs to run this setup which I do not like very much. So I tried to hook the tailfin actuator into the powerpro 3 and now everything is through the powerpro 3 controls. The only problem is that the speed of the actuator is no longer controllable and it goes full blast which makes it quite tricky. I am thinking of putting a 12 to 6 volt transformer in the wire going to the actuator so it will get half the voltage and hopefully slow the actuator down by 50 %.
Will the actuator speed actually go down or will it stay the same ?
As always, thank you for your advice.

I learned that a transformer is not the ticket ,but I found a dc speed controller for actuators so I'll take that route
