I looked at two 1994 Chris Craft Crowne's back in 2003. They both suffered from the same problems. They leaked around the deck hardware, fill caps and windows. Both boats had severe moisture problems in the foredeck, transom and stringers. The surveyor I used did some research and told me that Chris Craft didn't seal the weep holes or the transom cutouts around this period (1994) which explained the moisture issues. I never even got far enough into the survey to take them for a test spin so I can't say how the 5.8's would perform. One thing I did look into at the time was the possibility of converting to Volvo drives. At the time, I was told that it can be done easily on that boat, but don't hold me to that. It was 4 years ago.
Needless to say, I didn't buy either of them and bought my 95 Regal 322 instead (see sig).
