This is our first boat with an inboard engine
(Yanmar SB12) and we're planning to winterize tomorrow. I just have a few questions:
is raw-water cooled. Can we simply remove the raw water
intake hose from the seacock and stick the end of the hose in a 5-gallon bucket to flush it with fresh water
and then antifreeze
, or is there a special adaptor required?
We are also going to be removing our pressure water
system tomorrow. Once it's gone and no water is coming out through the foot pumps (because the water tanks
are empty), do we still need to pump anti-freeze through the water lines, or is that something that's only done with pressure water systems?
I know that we're also supposed to change the oil
(including the transmission
oil), top off the fuel tank
, and put biocide in the tank. Anything else I'm missing?
