Fair enough statement.
The only thing that i have done so far is drain it. The marina will happily winterize it for me here soon (next couple of weeks). The last boat stayed in a heated garage but this one does not fit (thus building a new garage for it - but is not heated) so i am going to a lot closer attention to it. Temps are now at the Lows around 34-38 degrees but only for an hour or so with highs in the daytime still around 45-60.
Knowing the real deep freeze stuff isn't here yet (but knocking on the door) i will get this to the marina soon.
Just for my well being, if i drained a fresh water cooling and left the valves, plugs and hoses off/open water for the most part was completely out of the system (which even though Lots of folks think that is good enough, I don't) On this system, if i drain via easy drain, where could water potentially be left? I guess where i am getting at is if the marina is still backed up, or if the deep freeze comes sooner than later (it is northern Ohio), what freeze problems could i possibly run into?
And one other thought, conversation....the TSB you quoted (05-2-2), if that covers all of their engines, you would think on an owners manual printed/released 01/2017 (for an engine/outdrive installed by Volvo OEM on Aug 17, 2017) would have that procedure of including AF? The only thing that it mentions about AF is to check coolant for proper fill level and freeze protection level (um DUH) Other than that, just drain water from raw water side of engine cooling system.
