Hi All, This winter I changed the water punp in my alpha drive. After I refilled the oil, it sat in my basement for a couple months, no leaks at all. Last weekend, I mounted the drive on the boat, and now I have oil leaking from a little hole on the prop shaft housing towards the front starboard side. I had the drive lying on it's side for maybe 20 min before I mounted it. Before I drop the lower unit, what might be causing this? Again it sat in my basement for months with no leaks (??) Thanks!
