winterization tips for 2000 Challenger M2 Mercury 240

[Barberbill66]

I have a 2000 Challenger 2000 & would like to do my own winterization. We live where winters are very cold so I have to run the antifreeze through the engine. Not sure where the fresh water port is to hook the hose up to for the flush? Can anyone show a picture of the location please? Thanks
