Ok, I am going to sound like an idiot here but oh well. * *We have a 10' avon RIB with a little evinrude outboard. *I want to mount the outboard on the aft rail since we only have weaver snap davits. *The dumb question is....winter is coming soon...I assume/think all the water drains out of the outboard as long as it is stored upright, yes? *I don't want to mount it on the aft rail only to realize I should have done something to keep from ruining it and having it crack due to a freeze. * *All boats have been inboards!
