The packaged electric motor systems I’ve seen are all plug and play. The challenge comes in the custom mounting of all the components to your boat. In my experience, the actual mounting of the motor was the most difficult.
The 424 presents a fairly straightforward installation as the boat has a great spot where the old Vdrive was. Mounting here puts you in close proximity with the prop shaft. However, there is the need for some kind of “spacer” of around 3.5″ needed to get the motor and prop shafts on the same plane.
I solved this spatial positioning by using 2.5″ square aluminum tubing. By attaching bolts with nuts pointing upward to receive the motor frame, I created an adjustable mount bed. Holes were bored on the opposite side from the bolts to allow socket tool access. This was also done for the bolts that attached the square tube to the old Vdrive rails. The pix below give a clear representation.
I had to have a custom coupling machined that would mount on the motor drive shaft and interface cleanly with the old prop shaft coupling. The couplings were mounted on their respective shafts and bolted together tightly. The adjustable mount bed was then used to perfect the shaft alignment. The last step was then affixing the whole assembly to the old Vdrive shelf.
After starting the motor for the sea trial, I was amazed at how smoothly the motor/shaft assembly ran!
Vibration was barely perceptible.Attachments:

The instant torque pushes an amazing amount of water in the blink of an eye. This makes forward and reverse maneuvering a snap. We had no problem docking to a starboard side tie in 15k of breeze to starboard. The really amazing thing is how the freewheeling prop turns the motor into a generator. While sailing with just the job in 15k, we were doing a little over 5k and regenerated probably half of the juice we used when we were testing the motor during sea trial.
