Anything special I need to do about boat

[Dink]

You run it lately? If there is any water in the motor it will freeze and expand. It is possible to have a cracked block from this. Make sure there is no water in your lower unit. Pull bottom plug then top. Water will settle under the oil so if any comes out the bottom let it drain till nothing but oil is coming g out. Same goes for Hull. Make sure there's no standing water in it.
