Not sure I even spelt it right but how to winterize a macerator pump? Seems like you gotta pump antifreeze thru it from the holding tank.

For what's is worth, and this is what I have done and do. I have owned 2 Sea Rays, and have winterized 8 times. I have NEVER used the macerator pump. I have NEVER opened the macerator sea cock. I have NEVER done anything to winterize the macerator pump and its sea cock.
Again, this is what I do.

Empty the holding tank, run a few gallons of AF through the heads then run the macerator until it’s blowing air through the seacock.

I do what Richard does then I look under boat, when pink dripping from hole, I know i am good. Only takes me 1/2 to 1 gallon not a few.
