Winterizing question

My ‘85 I/O isn’t self bailing.

I forgot to mention - if it’s an I/O, and has a heat exchanger, be SURE to drain that. it’s a $1000 part at retail.

You’re getting all kinds of good advice here. If the under deck drain pipe is clogged and the other methods don’t get it, you might try a small,plumbing snake but go gently so you don’t break the PVC pipe.
