I don't know how the Jeanneau is designed, but on my Catalina the cutlass bearing can be replaced without removing the propshaft. There is a $400 tool that attaches to the shaft and allows you to press the bearing out of the strut, then reverse the tool and press a new bearing in. Another C36 owner just reported having his yard to the work, charging 2 hours labor.
If you are about to set off on a long journey it may be worth the effort of preemptively replacing the shaft, but otherwise, you might want to simply replace the bearing and see if that does not adequately address the issue.
If you're saying you would like to inspect the section of the shaft covered by the strut, you should be able to separate the shaft from the transmission and slide it far enough aft to allow that. That process can be a problem and was the biggest expense when I had it done to install a dripless shaft seal on my last boat, but it certainly would seem a better option than moving the engine.
