Yesterday, I winterized my Catalina 310 diesel and water systems in anticipation of the, usually, not too harsh winters in the Chesapeake Bay region where I berth my boat. I am staying in the water this winter. I have one small question. I understand that some sailors spray WD40 or similar on the outside of their engines for winter layup. Is this important for the @ 4 months until my spring '24 recommissioning? Seems like it would just make the outside of my now clean engine a sticky mess.
