Depends how bad you want it! With a direct drive I would say no problem- engine is easy to access- use it, drain the block, drain the water pump, blow out the heater and transmission cooler, good to go. With a V-drive the access is more challenging but if you read over the winterization procedures and get 'er dry then go for it (don't forget about the ballast system). temps mid to low 20s I would definitely drain it or run antifreeze through it.
