The story on the damage.
The PO got ripped off and it was sold to him this way. He was not happy, which is why he was anxious to part with it.
Apparently, one time when he brought it into a shop (for leakage?) the mechanics recognized it and said they had replace the outdrive on it. That owner or the one before that, hit something destroying the OD. It was replaced with an SEI drive but the gel was never fixed. It leaked. I dont know who used it for how long that way. I know the guy I bought it from only had it out once or twice in the time he owned it, because it was taking on water.
