The first picture seems to show the whole bearing housing having dropped down below the deck Joe, but I can't see the four projecting bolt bosses that are parts of that casting - they don't seem to be there in that picture. I want to see decent pictures of that bearing housing, and the deck around the hole it used to mount on. That way we'll find out whether the four bosses broke off the casting, or a chunk of the deck broke out and dropped down with the casting, or as you say the four bolts fell out and for some reason I can't see the bosses in that picture.
