    Well, I would swear I have run into this “undrilled” situation before also, but it is hard to say….The problem is you have to be so careful, you must know where your drill is at all times, you sure don’t want to drill thru and puncture the oil cavity….I would certainly mark the drill bit with some tape or something to make sure you don’t drill too far.
    You have that gearcase all apart now, I would definitely clear the drain hole….Water trapped during the winter could split the housing open, have seen that happen more than once….
