There is nothing difficult or magic about winterizing and engine and water systems.
However, I have always let the marina handle this task....a concept called "risk
transfer". Let them pay the bill for a cracked engine block if the winterization was
not done properly.

More expensive? Yes. But a small price to pay for ease of mind.

It seems that everyone knows someone who has wrecked an engine by
improper winterizing. I was planning on just following the Mercruiser
engine manual and their recommended procedure. Having mentioned that
to a couple of friends, and their reaction, makes me wonder if there
is something that I should be aware of? Is this all just a mystique
perpetrated to get our money into the pockets of the marinas?
Should I do some additional reading at a URL or should the manual be
enough? For reference, the engine is a Mercruiser 4.3L I/O.
Thanks for any help!
