I think it is a good idea to have a spare encoder around. The encoders detect very small changes in magnetism and translate them into a sinusoidal wave. The sensitivity to magnetism makes them susceptible to EMPs associated with lightning.

Yes I had a faulty encoder on same motor and replaced it a month or so ago. Replacement itself is very easy - remove cover plate, unscrew 4 hex screws and unplug at board. Installation the reverse procedure. Pictures attached.
More complicated is that it then has to be reconfigured using the DVT software for the controller - fairly complicated - Thierry Lequeu at kit-elec-shop.com in France did it for me via a remote screenshare connection.
Hope that helps.
(Original failed when I returned to the boat after the winter and the motor did not work - it rotated about 10 degrees each time the throttle was applied and a humming came from the SEVCON unit. Thunderstruck were unable to diagnose but Thierry Lequeu at kit-elec-shop.com in France solved it for me - highly recommend him for SEVCON or motor issues for anyone in France)
With some remote assistance on Sevcon parameter adjustment the motor has more power then before - pushes a 9 tonne Gin Fizz to 6-7 knots - very happy with it.
Good luck, Stewart

Does anyone have experience replacing or repairing this part? If so, please share.
Thanks
