Hi Rudi, yes, you need to decouple the lower unit from the motor. In my experience, this will be difficult if it has not been decoupled in a few years. It will very likely require some heavy-duty mechanical pullers. It is likely that you will need to replace the soft coupling when doing this job.
There is an Amel procedure for decoupling the SidePower Bow Truster, but it is not very complete and probably will not help much. There is a SidePower publication as well. I wrote a procedure including some photos I took, my personal experience in doing this job, SidePower's information and the Amel procedure. It is in my Amel Book. However, you should be able to do this without my book, if you use the Amel procedure: (https://amelyachtowners.groups.io/g/main/files/Bow%20Thruster%20maintenance%20A54/A54_Bowthruster%20flex%20coupling%20replacement.pdf).
If it is stuck, like I believe you will find, you will likely need the help of a machine shop and mechanical pullers.
