Usually my boat sits in my heated garage and gets used on days above freezing. This weekend I am headed to a frieds cabin and Saturday nights low is 26. (hard freeze) I have a I/O 190 Merc cruiser (uses water from lake to cool the block) Will I need to drain all the water from the block and maybe add some anti-freeze before the Saturday nights freeze? Or will the block/hull be enough insulation to keep water from freezing and cracking the block?????
