The plastic blue seacock is frozen. From what I understand, this is the sea water cooling intake, feeding from the "holes" in the saildrive.
Since it is frozen, I can not disconnect the hose that leads from it to below the raw water pump
, in order to fill the pump
itself, the heat exchanger and the exhaust
with antifreeze. This was an easy 3 minutes procedure on my previous boat's Westerbeke: just close the thru-hull and dunk the hose in the antifreeze container while running the engine .
What is the procedure for the Volvo? Should I do that ashore, in order to be sure that the water pump
is above the water line
and will not sink the boat? Do I then "collect" the anti-freeze spitting off the exhaust
, so that my neighbor's boat do not get showered?
Has anyone replaced that "seacock"?
The fuel pump
is almost inaccessible: there is a second Racor fuel
strainer. Is it necessary to replace the Volvo fuel
filter? It seems it was replaced in 2010 and I suspect less than 100 hours on the engine since.
( This is urgent since I have to fly overseas and the yard takes the boat out of the water very soon...) Thank you !
I have to winterize ASAP in order to fly overseas.
How do I winterize the Isotemp waterheater? I emptied all the water from the tanks, via the faucets and the foot pumps. I opened the releif valve et the Isotemp, and let is flow. I got maybe 4 oz of water. Does that mean there is no more fresh water in the heater?
What about the "fluid" that circulates in the heater, in order to heat tghe fresh water? Is it raw seawater ( I don't think so... ) or is it antifreeze coming from the heat exchanger? Sorry, I am a bit confused in my life ...
