Could anyone out there assist me in winterizing an enclosed cooling system 496 ci.in. 375hp?

I dont know what the blue hand pump is used for thats clipped on the motor. For all intents and purposes, could I connect a hose to the outdrive and run anit-freeze through it, and not worrying about anything freezing?
Thanks Ray
