Chris,
If your boat is afloat, you will typically have no concerns until the temps get into the upper 20's, AND the interior temperature drops to the same level. Remember that the liquid water temp. will be considerably higher, like 40ish.
So the bilge area will be above freezing...
Now if you get winds that pull heat out of the interior, especially the aft end around the laz. hatch and vents, then the engine area could get down to freezing sooner than the main bilge.
A drop to 32 degrees does not unduly alarm me, but as the nights get below that at all, I want to have the raw water side of the engine winterized. In any sustained cold snap I also want the drinking water system drained/pumped dry, too.
Lots of folks like to depend on electric heaters to keep their boat interiors above freezing, but likely as not there will be a power outage exactly when the temps are lowest.
Sounds like it's about time for you guys to winterize...

Thanks Loren, the fresh water tank and lines were run dry two weeks ago, i am going up Saturday to winterize the motor on the raw water side, and winterize tge head and a/c system. Close all seacocks and pour antifreeze down tge drains and in the bilge.

I haven’t winterized since 2007 but had a cracked head and manifold last winter when the lake froze over. The coldest winter in several years. The boat has done well with lows down to twenty or even lower for lows. When we had high temps below freezing for several days that is what caused the engine to freeze. I will winterize this weekend or next. Don’t lose sleep over this weekend

Winterized the boat today, took an hour to go thru all 4 systems. I do have a question, why does tge head sink drain into the supply thru hull to the head?

my guess is...
I saw a thread on this site not long ago where someone patched the head supply hose into the sink drain. It allowed him to run fresh water to the head without the checkvalve issues associated with running fresh water straight from the water supply. Possibly, this is what your set up does.
