    Well, to be honest, no gearcase can withstand the pressure that ice creates when it expands while freezing.

    The real issue, is owner/operator error and laziness.

    Ensure that gearcase is totally drained before winter, and those drains are free and clear.

    They are very often restricted and plugged. I have to drill many of them out to clear the path. Even had to remove owner installed plugging devices! Guys don’t like seeing their gearcases draining nasty sludge, but that is very normal, and protects them from the damage you describe.
