I'm looking to buy a new (used) boat, and I noticed that there is a piece of the outdrive broken off. It's the very back corner on the bottom, most likely caused by a prop strike or something. It's probably only about a quarter of an inch in and maybe an inch long. Is there any reason why that would be considered a big issue? Only thing I could think of is that it might start rusting if not sealed off somehow. Any advice? Thanks
