Well I guess first you have to drained the gear lube or whatever might be in the gearcase if you haven’t done that? If it is full of water or goop the driveshaft might be seized in the upper or lower bearing housing? The propshaft would still turn freely in neutral. Of course the powerhead could be seized, rusty cylinders, etc. only letting it turn a partial amount, but neither would keep the gearcase from coming off. Unfortunately then we have to go to the splines of the driveshaft being stuck in the crankshaft, but that wouldn’t keep the driveshaft from turning. It would take a combination of two of these to cause your problem. Just trying to give you some of the options from my perspective. I am sure others will be along if I forgot the obvious. Hoping it is something easier/cheaper to fix. Those are great little motors. Plenty of parts available.
