    Simple answer is 100% YES…………………………………… But things need to done right and the process fully understood as to how it all “works” for your ( every ones) unique installation.

    In so many words, there is no “one size” fit all..

    My Cummins trained mechanic winterizes that way

    He just winterized my boat on the hard with a fresh water hose going into my Groco through hull service adapter.

    I also learned as part of that that you need 5 gallons of pink antifreeze and a 6th for good measure!

    Is there enough volume of water from a dockside water hose to flush a QSM11 while it is running?
