Never happened before.
I thought I would change oil and outdrive oil in early spring. If I winterized and kept boat outside, is there no more than draining the 2 plugs and supply hose? What about water in bottom of outdrive? What about fogging...whatever that is. I've heard people say something about that.When do you change your oil, allong with outdrive oil? Otherwise on a 3.0 all you need to do to drain the block is remove two drain plugs and probe for sand blockage with a piece of wire. You may also want to drain the cooling water supply hose. A few minutes could save you big time in the event of an ice storm.
