Hey 49er,
My advice would be to go to a Simrad system with nothing less than an RPU-80 hydraulic pump. Once you obtain the pump, get it to your builder and have them install it in your new hydraulic steering system.
As far as trolling motors go, if yours is fuel-injected then you're going to have all the fine throttle control you're ever going to need.
I would avoid plug-fouling carburated trolling motors.
There's really no comparison to a fuel-injected kicker these days!
