I have my first inboard, in my Shannon 28
Cutter, which is powered with a
Yanmar 3GM30F-YEU. I'm trying to learn the ins and outs of
maintenance myself. Is the winterizing of the
raw water part of the
cooling system, by pumping anti-freeze through
raw water hose intake, above the seacock, done in the
water, immediately prior to the haul, or
on the hard? I would assume the latter, in consieration of pollution issues, but wish to confirm this. Thanks.
