On my 02 330 SS , I tryed to back feed the antifreeze to winterize my A/C unit thru the A/C exit under the swim platform.
I got a good seal, but the antifreeze just came back in my face.
I had winterized my past boat with no problem for years by pumping antifeeze thru the exit with a drill pump
I ended up feeding it thru the sea strainer.
Question is, is there a one way valve on the exit of the A/C under the swim platform?
wondering why system would not take the antifreeze
thanks
