1. An axial flux propulsion system for an electric boat comprising:
a traction system for generating torque, the traction system including at least one axial flux electric traction motor/generator;
a transmission system for transmitting torque, the transmission system including at least a transmission shaft, a drive shaft, and a propeller;
an electrical power distribution system for storing and distributing electrical power, the electrical power distribution system including at least one battery; and
a control system, the control system including at least a communication system and a throttle that together direct the operation of boat subsystems;
wherein the at least one axial flux electric traction motor/generator is positioned on the transmission shaft that is connected to the drive shaft, the drive shaft being connected to the propeller;
wherein the control system directs the electrical power distribution system to adjust electrical power delivered to the traction system in response to signals from the throttle and communication system;
wherein the boat subsystems include at least the traction system, the transmission system, the electrical power distribution system, and the control system; and
wherein the traction system is a purely electric motor system.
