Outboards are self draining. You do not need any antifreeze. Dump some fuel stabilizer into the fuel tank. Run her on a flusher for a few minutes. Now spray some fogging oil into the carbs. Try to stall her, but if she smokes, but doesn't stall, turn her off. Now remove flusher and let her drain completely. Remove prop and clean propshaft. Drain and refill gear oil, and pump grease into grease fittings. Rinse block if you boat in saltwater. I rub some grease on bolt heads, just for fun.
