I am new to sailing again, sat out twenty plus years. My reentry went from 14' daysailors in my youth to my current
affliction, (see signnature )
This fall I winterized my Yanmar
, and I am still doing some head
Winterized it twice.
First time, ran PG pink through system from strainer before engine
till two gallons of pink came out the exiting thruhull.
Came to realize I did not run the engine
very long, and became afraid I may have left some water
in the block behind the thermostat.
Called a Yanmar
dealer, and he suggested I do it again with a warm engine or remove the thermostat.
This is the first time this sailboat has seen sub freezing temps, as it was a California
boat before I imported her to Nebraska.
My question in this. Why the odd (odd to me) arrangement of mixing the exhaust
fumes with the discharge water
from the cooling
system, and just how much does it mix? I see the mixing elbow
, but there is another box under a aft cabin
berth I do not understand.
