What Did You Do To Your Boat This Week?

Not sure I follow - are you trying to extract fluid from these lines or pump RV antifreeze into them.

Trying to get RV antifreeze into the pumps and lines that I don't need in the winter. The head, and the washdown pump are my main concerns. One suggestion has been to push a line into the through-holes under the hull and draw the antifreeze up. Another is to pop off the lines on the inside of the hull, and try to stick them into a jug of antifreeze to draw the fluid in that way.
 
How about this:

Step 1: buy 4ft of 1/4" tubing and a plug sized so you can effectively block your thru-hull fitting
Step 2: Drill hole in plug to match outside diameter of tubing
Step 3: Glue/seal tubing into plug, and then insert into thru-hull
Step 4: Insert loose end of tubing into container of RV anti-freeze
Step 5: Run washdown pump / head and it should suck the antifreeze up into the system.

If you want to get fancy, add a primer bulb to the tubing to avoid any risk of air locking the pump (if the pump isn't self priming).

Do a nice job and its a useful little contraption you can save in your winterization toolbox

I used to just out blow my water lines like irrigation lines.
Disconnect the hose at the pump and hook up your compressor on low like 40psi. Open all the taps and blow out the water.
Don't like having to deal with the antifreeze in the spring.
If you put an adapter in the line makes for an easy job each year

Filled her up with fuel, along with some fuel stabilizer gave her a cleaning. She is now ready for winter.
So question.. when you fill the tank with fresh fuel and add stabilizer, do you run the engines well to make sure the stabilizer reaches the fuel
In the lines, engine etc?
 
I had already did that. This was just topping the tank up to reduce the air void in the tank so condensation does not build up. With adding more fuel I had to add more stabilizer. I will most likely run the boat for winter spring fishing so I will not fog the engine unless plans change and I will be parking it for a longer period.
 
Did the basics last weekend, top up the fuel tank, stabilizer, winterization sequence on the etec, drain the water separator, squeeze in fresh grease. Took it to the carwash and rinsed everything out with a pressure washer. Ran out of time due to family obligations and weather.

Next up: lower unit gear oil, trailer brake fluid flush (sprayed down the bleeder screws with penetrating oil in advance), maybe disassemble and repack the bearings if I'm feeling ambitious. May do the water pump in the spring.
