Torqeedo motors have a much higher efficiency of around 50%. A Torqeedo motor will provide double the run time/range per charge compared to if you were using a Minn-Kota or similar trolling motor.
You might want to check the efficiency curves and technical info on the Torqeedo website here-
I hope that helps!
Price slaps ya in the face at around $1800 US.

An integrated rudder/motor like this is pretty much exactly what I had in mind making.
It is nice there is a commercially made version, but no way I'm paying 2k. More likely I'll take the lower end of a $100 trolling motor (like this Minn Kota Endura 30) and graft it to the rudder mechanism:

The linked site has an off the shelf relatively inexpensive kayak trolling motor which is premade to work with existing rudders...
I'll be curious to hear about your work jag, as I have a Greenland II folbot as well..
