John,
A whole system is out there, including joy stick, designed to mount on the transom. It's a combination of Lenco and MotorGuide. Here's a web site. It's been on the market for a few years but has not had a large acceptence as a trolling rig for larger boats (what it's been marketed for).
Here's a small boat that uses dif. thrust for steering with under mounted motors. I know these guys and have played around with one of the boats. It'll turn 180 in it's length.

Neat.One wild thought I had a couple of weeks ago was to build a smallish wooden boat, put two motors on it, and not put a wheel on it at all. The steering would be accomplished strictly by differential thrust. One thought was to possibly use a microcontroller to watch a joystick, and drive the motors based on the joystick. The motors could be mounted entirely under the hull, though I'd probably still want a "kick up" option in case the boat ever needed to be beached.Not sure how practical this is. But if it could be done with two trolling motors, each with a Torqeedo prop, then at least it wouldn't cost a fortune to try. The next question would be where to get transistors that could switch up to 50A??? :)JohnFrom: "'Glenn Holland' gholland1@nc.rr.com [electricboats]" <electricboats@yahoogroups.com>

[Attachment(s) from Glenn Holland included below]John,That last photo got cut off. In this one you can see what's what.Glenn----- Original Message -----Sent: Monday, May 26, 2014 2:59 PMSubject: Re: [Electric Boats] Torqeedo PropGlenn,That's great to hear!! (though maybe we should wait and buy up several props before word gets back to Torqeedo that their prop on a $500-$1000 motor would work "good enough" to avoid spending $3500 on a Torqeedo....)What size boat do you have?

[Attachment(s) from Glenn Holland included below]John,I'm experimenting with a torqeedo prop on a 24V Motor Guide now. I have not taken any calibrated measures but it seems to push my boat at hull speed with about 25% less throttle. Photo attached.keep it floatin,Glenn Holland
