Need advice with winterizing GTX DI

[Crankshaft]

Hello everyone, in need of some advice, I’m in Ontario Canada and it’s time to put the missile away for the season(2001 gtx 951 di) what’s the easiest way to run antifreeze through the motor so I don’t get any cracked cylinders, exhaust, etc. ?
can I just pour some through the threaded flush port near the jet pump or do I need to disconnect a hose and get it through top of cylinders? I see there’s a quick connect 3/8 line coming from bottom of motor, should I disconnect that as well for water draining? Any help appreciated.

I use a cheap drill pump from lowes. Start the ski then pump two containers of antifreeze through the flush port, fog the ski, change jet pump oil and that's it. Make sure when you pump antifreeze that the engine is running

I just poured a gallon with hose and funnel holding it up high while engine was running of course. Is that going to be fine? Or do you need to pump it?

Get a cheap submersible pump and place in a 5 gallon bucket with a couple gallons of RV antifreeze.
Put a catch pan under ski to catch the antifreeze that comes out.
Connect the hose to flushing port. Start ski then turn on pump.
Run until antifreeze comes out the pee hole in back of ski.
Turn off pump then shut off ski.
After removing pump, remove spark plugs and spray fogging oil in cylinders.
Reinstall plugs and leave wires on grounding terminals.
Holding the throttle wide open crank the ski for about 5/10 seconds to get fogging oil spread throughout engine and cylinder walls.
Additionally I usually put stabil in the tank and make sure it is full of fresh gas.
Disconnect battery and remove from ski. Place on wood with trickle charger just until fully charged then remove charger for the winter. I don’t trust trickle chargers to not cook my battery.
This process, give or take a couple things, has worked for me for years.

Thank you. I did this. Everything went good.
