I would check the lower unit oil to make sure there's no water in it to freeze and burst your lower unit housing. If so, reseal and refill. If no water, I'd fog the cylinders with fogging oil. If you're running the motor out of fuel, then you're also running it out of lubricant for the rings, cylinders, bearings, and such\---assuming it's a 2-stroke (you didn't say what motor it was). Just spray the fogging oil into the carb throats while turning it over with the spark plugs grounded so it won't fire. That will keep any rust and such from forming over the winter. You can get fogging oil at any decent outboard shop. Cheap, easy, and good insurance against any problems the next season.
Just my opinion,
