What temperature is anti-freeze good for on a boat?
Marine anti-freeze is good for up to -50 degrees Fahrenheit. If you choose not to use an anti-freeze, you must make sure that you have fully drained any remaining water that’s been left inside the engine and lines. When water freezes, it will begin to expand which is what causes the engine to crack and lines to burst.
Will a boat motor freeze up if it's not running?

How to determine if water freezes in engine?
The surrounding water will keep it from freezing. To determine at which temperature water would freeze in the engine depends on what the water to anti-freeze ratio is that it is in the engine. For example, you could use a 100 percent ratio of a marine anti-freeze that will protect your engine from freezing in temperatures as cold as -50 degrees ...
