I know that the best way to leave an outboard in the water during freezing weather is to lower it in the water so all the water can drain out. I get that. But if I flush out the motor, lower it back down to drain and then trim it up again will I not have to worry about the water in the engine freezing? I just don't like leaving my motor in the water.

There will be water in the water pump, and you'll be screwed if you leave it up in freezing weather. Why don't u like leaving the lower unit in the water? That's where it belongs...

We keep the duck boats in the water all winter with the motors down to prevent freezing..spray lower unit with anti-fouling paint and put in fresh worries

Corrosion, especialy due to stray electric currents. Maybe I'm being too fanatic.....

The stray electric currents will be taken care of by the zincs and there will be less stray currents as more boats are out of the water.

Your biggest concern with freezing if you leave the engine tilted up will be the water that is in your "bullet". When you tilt the engine up the prop hub acts like a cup and scoops up water and fills the bullet of the lower unit, the exhaust chamber. If that water freezes it will crack the lower unit case, seen it happen a few times. You also don't want any water in your water pump freezing as was mentioned or any water that is in your gear lube.

Your best bet is to just flush the engine without tilting it up and then just leave it down, that way your powerhead will drain and your lower unit will just stay in the water.

after flushing why not add some antifreeze
and lower the engine to save the lower gear case

the Edit: Check what oil you need to have, I have a E-Teck and that needs the 100 oil for weather below 30
