Using my boat in winter

[treysheek]

We have a boat with a four Stroke egnine & we wanna use it this winter on nice days. I have been told that the engine needs to be flushed with antifreese and I have been told that all the water drasins and it will not freze. Formerly what should I beleive?

I do not owe a 4 stroke but a 1983 Envinrude. I fish all year long mostly including in the winter. Although the lakes & bayous don't ice over we do occasionally have temperatures that will get down in the low 30's for several hours. It is enough to freeze over water in a bucket or hose. We I return from fishing, I always flush my motor with fresh water then lower it for about a half hour or so before raising it back to the ruefully tilted position.
I never had water freese in a motor.
