Dave, I have a nearly new 24 volt MinnKota Power Drive V2, 70# thrust, 54" shaft. It is not a hand steered model like you want, but maybe you would be interested. You can see it described on bassproshops website

I bought it new and used it 8-9 times. It had a little problem and was repaired by the MinnKota Authorized Repair (Master Repair, Stuart). In the meantime, they had gotten in a new (but now discontinued) Genesis model like I had when my boat was new, and liked it better than the one I had bought. Anyway, I bought the Genesis and now had a nearly new PowerDrive to sell. Counting the quick disconnect mount, I spent $700 plus tax for the PowerDrive. I would take $375 for it. Price new is now $679 without the quick disconnect.
If you are interested, call me at 954-563-9238.
