Re: leaking antifreeze

If it was winterized by running antifreeze through the raw water side, it's probably just antifreeze that was in the pump.
The coolant level could be low for another reason.
To check, drain the antifreeze out of the engine and cooling system and pressure check it.

If the boat has been running, a quick check would be to pull the aft (seawater side) plug in the heat exchanger. If antifreeze comes out, you most likely have a bad heat exchanger that is allowing antifreeze to leak out into the seawater side.
