Would there be any benefit to leaving the block full of antifreeze instead of draining it? This would probably assume that you are using the automotive antifreeze. Seems like the anit-corrosion additives would help to protect the water passages in the engine, instead of allowing them to be exposed to air. I would still advise draining the risers/manifolds to limit the chances of anything weeping into the cylinders.

Any thoughts on this?

What!!!! Karl buys a house in Ft Lauderdale and is not bringing that bad boy down? The first nice day down here he's calling Wally, hehe
Key West Poker Run Nov 17-24th!

Troutly, do you pull the thermostat housing to fill up the block with antifreeze??

Just some updates......I jsut did a little bit of surfing on the web and read afew different lists and took some stuff they had we didnt:
I added to #16,29,31
and #22,23,25,26,and 30 are new!

i think we have it down 100% now. any other suggestions?

Shouldn't #17 come before #16? How are you going to operate the power trim with the batteries removed? Sorry - just being picky!

Sure as hell someone out there will do the list verbatum and get caught by this! I write user manuals for software as part of my job, and you would not believe how precise you need to be for that.

Great list, BTW...

hehe....good catch Budman! someone would have got it sooner or later!

Upon completion............Crack open a beer and give your girl a goodbye kiss and a pat on the ass and tell her you'll be thinkin about her all winter

This will be the first year I do the winterizing myself so I have a couple stupid questions. How do you suck the anti-freeze into the engine? What kind of anti-freeze do you use?

Bam Bam.......theres a few different ways you can get anti-freeze into the engine depending on what setup you have.
Lets say you have a Bravo drive or any drive for that matter that takes cooling water in through the drive. You can get your self a 5 gallong bucket, go to the hardware store and get a fitting to install into the bottom side of the bucket so you can attach a garden hose to it. You can buy a 6' length of garden hose fro the hardware stor and there you have a greatway to hook up to the earmuffs that fit on the drive. All you would have to do is fill it with your anti-freeze mix and put the bucket on a ladder or step stool higher then the drive is so gravity will feed the drive at the same time it sucks the mixture in.
If you have a thru-hull water intake then you can unhook the hose from the pickup. Or hopefully teh boat has some sea-strainers that you can pop the top off and fill right there.

As for the kind of anti-freeze to use? Again that depends on how you will be springerizing(?) the boat next year. If you plan on starting the boat and you can recover the antifreeze then you can use the green automotive stuff. JUST DONT USE THAT STUFF IN TEH FRESH WATER SYSTEM OR ANYWHERE ELSE THAT MAY BE USED IN CONTACT WITH PEOPLE!
Best way is to get the bio-degradable stuff .....west marine and boatUS sell the stuff and come spring you can just dump the boat in the lake and not worry about contaminating anything.

Thank you Wally, that is some great information!!!
