Good morning, all...

I can't apologize enough for having to ask this question. It is evident that this topic has been beaten up enough... but I've combed through the forum and have yet to find an answer to my specific question.

I have a '99 Challenger w/ Twin Rotax engines. This is my first year of ownership and have decided to tackle the winterizing project myself. After researching the topic, it seems as though pumping RV antifreeze through the hose intake ports (back of boat) may be the simplest method of flushing the water out and the antifreeze in. For those of you who are familiar with this method, how/when are you fogging the engines?

My hope was to spray the fogging oil into each air intake box, until the engines choke out. I would then follow this up with spraying the fogging oil directly into the top of the cylinders. Doing this prior to flushing would be counter productive to fogging, correct? And doing this after flushing would be counter productive to flushing, correct?

What am I missing here?

Thank you for your time and input.
