Hello all,
I have a 5.7 mercruiser with an alpha gen II drive. I replaced the thermostat today as preventative maintenace for next season and decided to winterize the boat while i was at it. I pulled all the drain plugs and let the water flow out. I poked around to ve sure of no blockages and blew through the system until no more water came out. I reinstalled the plugs and filled the block with antifreeze. I then pulled the plugs again, drained and refilled. Next i poured antifreeze down the hose going from my thermostat housing to my risers, watched for antifreeze to come out drain on bottom of manifolds, and reinstalled plugs. During this process I noticed that antifreeze came out of my water intake holes on my outdrive but nothing came out of my exhaust ports or exhaust bellow. By doing it this way is it possible that I still have water in my y pipe or would any water left in there drain out due to gravity?
