Engine flush or drain?
I wanted to get the experts opinions on how well the 5 point drains work on Mercruisers. I have a 2003 350 MPI with the 5 point drains. So i have always fully winterized by sucking up some antifreeze through the outdrives. This year i am on a lift and really want to take a few trips out later hopefully in the snow. How safe is it to just open up the drains and let all the water out vs going back through the process of pulling antifreeze through the system? Any experience here or tips would be appreciated. It wouldn't be such an ordeal but i have to pull a float around to get to the outdrives. Not really something i want to do later when it gets bitter out.
