Unless you are applying force to the shaft it will stay where it is.
I said if you are not going sailing or getting towed it will not fall out. Are you putting in another engine
? Do you intend to move the boat
before you put in the new engine
? If so put a zinc on the inside of the boat to prevent the shaft from sliding out. In the boat is staying where it is now you don't need to worry.
