Sorry to hear all this bad luck
In any event, go ahead and drain the gearcase. If it is full of water or burned/black oil, the gearcase may be seized. The prop shaft would still spin in neutral if the pinion was seized.
Nonetheless, who reinstalled the gearcase after the boat yard rebuilt it? The darn thing sure shouldn’t have been jumping out of gear, perhaps the linkage/control cables aren’t properly adjusted. Improper adjustment would not seize up the gearcase though.
I would bring the engine back to the repair shop if you fear the gearcase is seized, don’t give them an excuse to deny coverage by saying "you messed with it".
Hope the problem turns out to be something simple, like the flywheel rubbing on coils, sorry but I don’t live near Allentown. Don
