Guys,
I'd like ask for bit of advice.
My boat is currently winterized and I'll be heading for a 3 day fishing trip in a week and I'll have the option of leaving my boat tied up to a small, protected dock in the river overnight instead of launching and retrieving daily. Average overnight temperatures are expected to be around 24F with a daytime max of around 37-43F.
Would I have to drain my engine block at the end of each day if I were to leave my boat in the water or would it be safer to drain and leave it on the trailer each night? This will be much less desirable as I'll be launching and retrieving alone.
Thanks

While no pro, i would say you are always "safer" by draining it.....but dont forget, since it will be in the water your out drive will not freeze and it will absorb heat and transfer it to the engine....personally, i wouldn't go at all(to cold).... but if i did, i would leave it in the water, and maybe drain it after day two....

Why not leave it in the water and drain the block?

my fingers hurt just thinking of draining an engine at 24*F but that's what I'd do...drain the engine and manifolds and pull off the big hose on the circulating pump on the bottom and let that drain out to so the water in there doesn't freeze...finally I'd pull off the raw water intake hose from the thermo housing and drain it too (carefully since water can come in the boat depending on how low it is relative to the water line)...this is one of those situations where an outboard is just plain BETTER....

I would leave it in the water. No worries on the outdrive and just put a block heater in the engine compartment. Not going to take much. I was told by a marina/boat repair owner in Coeur d'Alene it is 6 hours below 32 degrees, you will hurt your block. I always worried if it ever dipped below 32 for any amount of time. If it is going to be that cold, you will need to do something every time(day) to combat the cold during that period it is below 32.

BTW, if it's that cold isn't it ice fishing?

24 deg is a hard freeze, drain it.

Well over the years of living in Montana and Wyoming and such.
That frost plug engine block heaters are standard Equipment on my boats.
That way if i run south to warmer waters for a get away and then come home to Utah now just plug them in and if I missed a little water I am Ok and they are way cheaper then a new BLOCK.

24F is fairly cold, but two other considerations are in order:
How long will it be at 24 F and what wind speed is expected?
A moderate wind will cool things off faster than if the boat is just sitting in dead air.

From the original post I felt there was no electric at the dock. A light bulb would do the job if there is.
I wouldn't take a chance on an expensive piece of iron. It is easy to drain an engine in the water.
Why take a chance?

You can buy explosion proof lights that are Hazmat approved. :arr.
Some put off some good heat and your boat will still be safe. :)

Thanks for your thoughts Guys.
I believe I'll have to play it safe. I'll retrieve daily and leave it overnight on the trailer with the engine drained, no matter how inconvenient it may be to do so alone.
I won't have access to electricity near the little makeshift "dock" which is on a remote part of the upper Columbia River. Its in the "high desert" in Eastern WA, where there are large differences between daytime and overnight temps. The river itself isn't freezing but the nearby lakes are frozen.

PS then when you do get it on the trailer and out where you are going to leave it tilt you outdrive down so it can drain out.

We used to visit the tri-cities to race our dirt bikes at Horn Rapid's in April...it used to get real cold at night even then, had to make sure we had anti-freeze in.
Probably best to take it out and drain. Maybe consider a closed cooling system in the future if this happens often.

Best advice I can give is buy some neopreme gloves - cuz my fingas don't work in the 20's. Removing the drains is like turning a door knob with chop sticks for me when it's that cold.

IMO - draining would be a must for you to get any sleep. I would constantly be wondering otherwise.

I'm with Doug.

I left mine in the water this year and took it out a couple of times.

On each return I drained and fogged the engine. No need for you to fog, however, but draining is no big deal and a REAL easy guarantee for a good nights sleep.

Just make sure you know the pathway of freeze-able water and get it all out.
