Maybe this is an odd question but I got to thinking about this the other day while driving.... if while parked outside rainwater gets in the exhaust opening in the lower half of the drive through the prop hub does it have a way to drain out or does this become a freeze hazard in the winter? Alpha 1, gen 2. Just curious as I know there are several boats that sit outside int he winter but I don't know that I ever see one covered so I guess it must not be a big issue typically?
