You only need 1 freewheel between engine and its connecting rear sprocket.Yeah, I was worried about that. I am not really into any of this stuff and have little to 0 knowledge on how to make this work. My thought is to have the trolling motor behind the trick and run the chain to the rear drive axle. I am assuming I will need a freewheel sprocket on the rear axle, just like what is currently there but a larger diameter. Then run another freewheel/oneway sprocket directly on the shaft of the trolling motor.
Are you saying that when I power the trolling motor it will be spinning the rear axle and cause the pedals to rotate?
There should be an existing freeweel between pedals and the drive wheel.
