On my M I added flush bypass valves so I can pull antifreeze through the engine while boat remains in the water. I close my sea cocks then open the bypass and connect hose to them and pull from a bucket.

1. Close your thru hull sea cocks.
2. Drain engine manifolds and block. six per engine. I also open the large plug on the rear of my log manifolds.
3. Make sure the drains are open use a wire to remove rush sludge etc.
4. Put plugs back in.
5. Remove thermostat. Very important!
6. Put 4 gallons of non toxic antifreeze in bucket and insert hose in bucket.
7. Have helper start engine while you keep hose in bucket. Shut off just prior to sucking air. (I can do it solo )
8. Close bypass valve
9. Install thermostat with new gasket if needed.
10. Disconnect coil wire.
11. Pour 6 oz of Marvel Mystery oil or fogging oil in carb.
12. Turn engine over for 3 seconds. The vacuum wil suck the oil into the CYLs and valves.

Engine is now winterized.

Safe storage,

I like your method. :)
I do have a question. What about the transmission or power steering cooler? Don't these chryslers have one or the other? Does it need drained?

When you pull non tox through the strainers it will flush out the transmission coolers.
No power steering cooler. No power steering on my Big M
