First unless the temp of the water is close to 5C then I would not worry about it if (THE BIG IF) the air temp has stayed above 5C during the day. Now that said, its not my boat and I do not guarantee. This is just what I would do if it was my boat.

That said, if it was getting down to 5C, my boat would already be out, winterized and put to bed

Still got some fishin' to do. Been about 2*C all day. The water is likely 50*F. Just a cool snap hopefully going to warm up a bit. Sorry about switching to F, but my finder set in F.

I think most of us understand that 0*C is 32*F, which is pretty much all that matters.

The water will keep your bilge warm

the water will keep your whole immediate area warmer than the forcasted drop

If your concerned, run an extension cord and put a trouble light in the bilge

Do I need to worry?
me personally, anytime it even gets close to freezing, i worry. frozen blocks and manifolds can be prevented.
If your concerned, run an extension cord and put a trouble light in the bilge
again. me personally, i'd change that to "If your concerned" drain the block and manifolds of water. air don't freeze.
i've thought about this light bulb idea much in the past and concluded for me, that i'm not a fan of putting an alternative ign. source into my bilge. a broke light bulb, or water accidentally contacting 110v and some fuel vapors might equal disaster.
who knows. it might be about the same amount of time to run the extension cord and put the light bulb in the bilge vs draining the block and manifold.

I winterized my boat last week when it was 92 degrees. That seemed wrong. One week later, the low was 34. I hate ending the season, but rolling the dice trying to get another day of boating could be a $15K mistake for my little 8.1.

34 is still above freezing.Even at 32 water doesn't freeze instantly, a lot more latent heat has to be removed for water at 32F to become ice at 32F

On the one hand the boat is sitting in water that is much warmer than the air, this makes a freeze up less likely. On the other hand, how long will it take you to drain it? On my engine if I remove half of the rear seat (about 10 min) and the rear wood bulkheads, I can drain the engine & manifolds in about 10 more min. 20 min to not worry at all. If the boat was on a trailer I'd say for sure drain it.

IMHO in the water (10C) at -2C for 6 hours, I would not worry about it. The engine is enclosed, and the outdrive is submerged in relatively warm water. Any heat lost to the air by convection will be quickly replaced by heat conducted from the water through the metal of the outdrive.

Heh you must be in my neck of the woods (calgary?) which is the reason why I haven't taken the new acquisition out for a test run since getting it 2 weeks ago. I'm eager to go but wife says it's too cold for the kids, especially our 2 year old. But the plan is to go next weekend, no matter what. I mean, isn't this what jackets and mittens were made for?

Nice to see a fellow Canuk on the boards, even one from Calgary:D.
The OP is in Winnipeg, clearly a cold city.
I haven'tr even taken mine out this year, I was planning to do it in Sept, but we have been in the deep freeze the past 3 weeks. Yet a couple of days ago it was like 28 in the Fraser Valley. From desert hot to the north pole in less than 800 km

Well guys, just to let you know, we had a very snowy and unseasonably cold 1st week of October here in Winnipeg, Manitoba, Canada. I did not winterize either my camper or my boat. It went to -6*C a couple times and the water went to 42*F. Nothing froze, but I think that was pushing it a bit.

Boat is at home now in the heated shop in need of a serious cleaning. Hope it warms up a bit before winter sets in.

Thanks for all input and advice!

Ken
