Freezing temperatures


Michigan boarder

Recommended Posts

Just in time!  I drain the last boat when the forecast hits the low 40s or high 30s.  This has been a cold early Nov. in the Midwest.

You're braver than me.  If you love late boating so much recommend you get a bilge heater for peace of mind and comfort.  That must have been cold on the hands.

Actually it felt great to have water hitting my hands, a sign that it was not frozen! 

The boat has been parked since Sept 14th, "just too much going on".  Which is really stupid, it took me all of 5 minutes to drain it.  At lunch I'm going to reassemble and pour antifreeze in thru the J hose.

Wow....about 80 yards away is another business and I can see water shooting up the side of their building behind some bushes.  I'm guessing they froze a pipe!

It's common for me to just pull the plugs every time I take the boat out of the water when we start seeing lows in the lower 30's. I don't trust the weather man enough to leave them in and it's too easy to just do it while I'm there than to have to drive up to the lake in a panic. 

On a side note there's no winterization in sight here in Georgia!

We'll be on the lake this Friday, and my son probably won't even wear a wet suit.

@chief  Good catch for sure!  Was just going to bring up pouring some room temp antifreeze through the block to make sure there wasn't any obstruction anywhere else but looks like you're doing that.

Waiting for Malibu to incorporate electronic ball valves on new engine so u can hit a switch and all 5 water drains open automatically.. wired in a way it can not be done with engine on.. 

maybethey can make it auto temp sensor in engine compartment .. hard wired to battery when engine not on to still auto dump below x temp.. seems pretty easy.. but what a selling point!

Also a catastrophic failure point. 

@Michigan boarder I got mine drained Monday. There was one night about two weeks ago though that when I got in my truck to leave for work it said 28 degrees! I know It takes some time at freezing temperatures to freeze a block but I was was worried more about my heater core. Was happy to see everything drain normally on Monday.

A few years ago I did a test using the type of temp monitors we use to track refrigerated trucks and saw that the engine compartment temp lagged the outdoor temp by about 2 hours in weather with a high of @40 and low in the mid 20s (what we typically see in the fall).  I imagine the block temp would lag by more.  So if its not going to be below freezing for maybe 4 hours then you're fine.  How far below freezing would also effect the time so you would have more time if it only got down to 30 than if it got down to the low 20s.

LOL, like the old mercruiser single point drain/block cracking system?

Problem is that if a human does not see that water is actually flowing you have no idea if your drain(s) got plugged up without draining the water

Honestly why not tie all of the five drain points into one single line with a single point of drainage something like that to make it easier than crawling all around the boat

Agreed.  How difficult would it be to engineer a single and accessible drain point?

I would very much go for this.  I like the idea of being able to summerize early, winterize late, and be able to reliably drain during both times.   My '17 VLX does not seem to make this easy.

Or switch that controls about 5 valves.

Not that hard, but a bilge heater is so much easier and lets you keep the anti knock sensor.

You guys reinventing the wheel today? Do some searching on this forum. It's all been discussed. Petcocks, quick release heater hoses/caps. A product that was a bunch of pipes & valves so all you had to do was open the valves & it all drained. Globe impellers. Etc. Not quite as fancy as a switch, but it's been working for me for years over multiple boats.

Got tired of posting the info here & being told it'll never work. Well, it works. I know a handful of guys in Seattle & Portland who have been doing it for years too. I've already winterized mine a couple times this fall. I did it at the ramp, took less than 5 minutes. And no tools.

I mentioned above but as mentioned a possibile failure of valve not working leads to a big problem.. tie em all to one point one valve at end would be best so u can visualize and confirm water coming out. Bring em all together near tranny  and have one valve there and tranny bolt only two things then in same spot.. or add tranny bolt connector of some sort

as I said.  Mercruiser used to do that.  Problem was that one of the drains could clog at the source, you would never know and walla - cracked block.

After having to clear my drains out with a piece of coat hanger to get them to empty this year I can't imagine using an all in one valve would be safe, at least for me with an older motor.  

The simplicity would be great though.
