inboards and freeze protection

[Miles Offshore]

as long as you have antifreeze in the block i wouldnt worry too much about it- if you are you can close off your seacock and drain your strainer and saltwter manifild lines. I never bother with mine and dont have any problems- although your prolly getting a little colder up there than we are- if you are really worried about it you can get a couple bottles of the 50/50 antifreeze stuff and run your intake line into it and suck it into your saltwater side. Again unless its going to be teens for extended period of time I wouldnt worry too much about it- jmho
