Hi James,
Great site.
You mentioned one advantage of an electric motor is the ability to remove the prop shaft through the cabin without having to drop the rudder. That is so true.
I just pulled my boat to paint the bottom and change the cutlass bearing. I had planned to make one of those cutlass bearing pullers that you can use to remove the bearing without removing the shaft, but realized all I had to do was raise the motor up within it's mounting frame (SolidNav Explorer) and slide the prop shaft out.
Another benefit is cleaning the prop shaft by turning the motor on at a low RPM and wrapping a piece of sandpaper around the shaft.

The object of the website is to demystify electric boat design issues and let people make educated decisions about repowering a boat with electric propulsion.
